Revision 1, 11.20.14
Installation Instructions INS-ACA035 2.0 Scope This Splice Box has the following advantages: 1. Capable of storing a minimum of 30 ft. of optical unit per ADSS and/or Unarmored Loose Tube cable inside of the (B8424) Splice Box for immediate or future splicing. 2. The (B8424) Splice Box can be premounted because of its internal unit storage capacity. Typically the Splice Box is mounted to the pole or tower 15-25 ft. (6.1 meters) from the ground. 3. Creates a neater installation of the routing of cables into the (B8424) Splice Box. This eliminates the necessity of coiling of extra cable onto the pole or tower. 3.0 Precautions 3.1 Health Optical fibers are very thin, fragile, and sharp. Therefore, careful handling is required to avoid either damage to the delicate glass fibers or, more importantly, injury to the technician or bystander. Small fiber scraps should be deposited on strips of adhesive tape, placed in a bottle or vinyl bag, properly disposed. Do not eat or drink when working with optical fibers as small pieces of glass may inadvertently be ingested. Never look directly at the end of a fiber unless certain that no Laser Light is being transmitted through the fiber. 3.2 Work Environment Handle optical fiber and fiber cable carefully, taking care to impose no damage by physical shock or sharp bends. During the actual splicing, care must be taken to keep hands and work area clean in order that the fibers may be kept clean. Dirty fibers mean poor splices! Keep all tools and equipment in their proper cases or storage pouches when not in use. Consideration should be given to the work area in which the splice box will be organized. A clean, snag free horizontal surface (protected from wind) is necessary. 4.0 Cable Preparation 4.1 After the stringing or pulling procedure there should be a minimum of a 100 ft. of ADSS and/or Unarmored Loose Tube cable from each pulling direction at the tower. The 100 ft. of ADSS and/or Unarmored Loose Tube cable is measured from the base of the tower. 4.2 When marking the ADSS and/or Unarmored Loose Tube cable use yellow or contrasting color tape to ad in visibility. Form the ADSS and/or Unarmored Loose Tube cable into drip loops where they will enter the connector body at the splice box. Mark the individual cables at these points. These Marks will be referenced to as Mark A. (See Fig. 1.) Fig. 1 SPLICE BOX IS NORMALLY MOUNTED 15-25 FT. ABOVE GROUND. B CABLE DRIP 15-25 FT.

Installation Instructions INS-ACA035 4.3 Measure 30 feet from each individual ADSS and/or Unarmored Loose Tube cable from mark A toward the Free End. This will give 30 feet of optical units for storage and splicing. NOTE: These measurements are based on the splice box being mounted 20 feet on the structure. 4.4 From point A measure 2 3 /4 inches toward the loose end of the cable and carefully ring cut the cable. The ring cut will point B (see Figs. 2 and 3). From the ring cut to the loose end of the cable remove the outside jacket/coating. Therefore, from the loose end, expose 4-6 inches of the rip cord. Then, grip the rip cord and pull to point B. Remove the jacket/coating. Fig. 2 Fig. 3 POINT A 2 3/4" POINT B 2 3/4" POINT A POINT B FIBER OPTIC UNDERGROUND CABLE 4.5 If Kevlar is present leave 20 inches from point B toward the loose end of the cable. Cut the Kevlar at this 20 inch mark and remove from that point to the end of the cable. Should the ADSS or Loose Tube cable have a inside jacket measure from point B out 7 ft. toward the loose end of the cable and mark with a contrasting tape (black may be poor choice). (See Fig. 4.) Call this new point, point C. Carefully ring cut at point C. DO NOT CUT the rip cord or nick the fibers bearing tubes. Fig. 4 POINT A POINT B 20" OF ARAMID YARN FREE END OF CABLE POINT C 7 FT. This is for the removal of the inner jacket to the loose end of the cable. Therefore at the loose end of the cable, expose 4-6 inches of the rip cord, pull this cord to Point C and remove this jacket. 4.6 Now remove the mylar tape and string binders. Remove short sections of the string binders from the loose end (a mono carbon cleaner works well). www.aflglobal.com or 800-866-7385 6 2011, AFL, all rights reserved. Revision 1, 11.20.14
Installation Instructions INS-ACA035 4.7 After all of the binders are removed, carefully roll out the FRP Central Member. Be very careful not to collapse the fiber bearing tubes. Remove the RFP about 1/2" (± 1/8") or 1/2" (± 5/8") from point C. Clean and dry the area around point C. (See Fig. 5.) Fig. 5 POINT C NO FRP OR STRING BINDER 5.5-6 FT. END OF CABLE 4.8 With the FRP member removed and point C dry, retape this area in a spiral manner with a 2 ½ to 3 vinyl tape i.e., from point C to about 5.5 to 6 feet from the cable end. (See Fig. 6.) Fig. 6 POINT C START TAPE END TAPE 5.5-6 FT. END OF CABLE 5.0 Cable to Splice Box Preparation The section will explain how to install the cable into the splice box. This should be performed when the individual ADSS and/or Unarmored Loose Tube cable has been properly prepared. 5.1 Position the proper size cable retainer against the tape at point A and put a wrap or two of tape at both ends of the cable retainer on the cable only. 5.2 Install this cable into the splice enclosure until the cable retainer is properly positioned and locked in the connector body. Always be careful to support the cable while inserting it into the splice enclosure so that the tubes are not damaged in any way. (See Fig. 7). Fig. 7 OPTICAL UNIT CABLE RETAINER 5.3 This procedure must be done to each of the type of cable installed in the enclosure. www.aflglobal.com or 800-866-7385 7 2011, AFL, all rights reserved.

Route the optical unit(s) so that they lay on the center shaft of the splice box during the feeding process. This will keep the optical unit(s) from kinking. 5.6 After all of the unit(s) have been fed into the enclosure insert the cable with the cable retainer into the connector body of the splice box. Make sure that the cable retainer is aligned properly and inserted completely. Tighten set screws. 5.7 Each fiber unit(s) should be supported and attached with duct tape to the outer diameter of the splice enclosure (see fig. 9) as soon as the cable has been secured into the connector body. This will secure the optical unit(s) to the splice box and prevent them from kinking. 5.8 If Dielectric Cables are being used, the connector body may have a conduit fitting attached to it. To verify the cable retainer on the Dielectric cable has been aligned properly, remove the top allen screw and visually align and tighten set screws. 5.9 Repeat all of these steps for the remaining cables that are to be installed into this particular splice location. Remember to prep only one cable at a time. 6.0 Anchoring the Optical Units 6.1 To anchor the optical thread the yarn through the eye-bolt and tying in a series of half-hitches. Make sure that the yarn is tied off in line and to the eye bolt in the proper position from where the individual cable enters the splice box. Repeat the following steps for the remaining cable(s). Tape the optical units together after they have been secured to the eye-bolts. (See Fig. 9.) Fig. 9 30 FT. (TO FREE END OF CABLE) DUCT TAPE TIE OFF THE YARN ROUTE OPTICAL UNITS BEHIND YARN ENTRY BUSHING RETAINING NUT NOTE: There should be 50 ft. of optical unit(s) prepped for each individual cable that is to be inserted into the Splice Box. The 50 ft. of optical unit(s) is broken down into two sections: 1. 20 ft. from splice box to ground, and 2. 30 ft. for storing and splicing. Should the Splice Box be mounted at a different height, then adjust the amount of cable to be prepped, stored and spliced to fit. www.aflglobal.com or 800-866-7385 8 2011, AFL, all rights reserved.

Installation Instructions INS-ACA035 6.2 Tape (duct tape is recommended) the units to the top outside radius of the box. (See Fig. 9.) This will help support the units and prevent damage of the units at the bushing. Also explained in Section 5.6. 6.3 Tighten the retaining nut so that the bushing is sealed around the units. 6.4 Tape the optical units together every 2 feet. Stop taping the optical units 6 feet from the free end. Tape each individual optical unit(s) 4 ft. 10 inches from the free end. Remove the yarn and tape from the optical unit(s) from the 4 ft. 10 inch section from the free end. 7.0 Optical Unit Preparation 7.1 Starting at the Free End of one of the units, separate the individual colored units one at a time by unlaying them back to the 4 ft. 10 inch tape mark (This only applies to the multiple unit configurations). Now proceed to the other cable units and repeat the same steps. 7.2 Mark the individual colored unit(s) 4 ft. from the free end with a permanent marker. In case of multiple units pair the like colored buffers together. (For example: Match the blue units from each of the cable units. Orange to orange, green to green, etc.) 7.3 With a buffer tube cutter, ring cut the tube at the 4 ft. mark. One or two revolutions will score the tube enough. Remove the buffer tube cutter. Grip the buffer tube on either side of the scored area and bend tube back and forth until it breaks. Remove the buffer tube slowly exposing the fibers. 7.4 Remove the gel from the fibers. 7.5 Then verify that all fibers are identified. 7.6 After the like cable optical units (blue to blue) have been prepared, cleaned and separated, tape the blue units together by placing a piece of double-back tape 1 /4 inch back from the end of the outer jacket material of the optical units. Place the double-backed section of the blue units onto the splice tray and secure them to the splice tray with tie-wraps. (See Fig. 10.) If multiple units exist, follow the same steps for the remainder of the like-colored units. NOTE: The felt serves to cushion the optical units from the tie-wraps to be applied. Fig. 10 CLEANED FIBERS PLACE THE FELT 1 /4 IN. FROM THE END OF THE OUTER JACKET MATERIAL TIE-WRAP OVER FELT INSIDE UNIT UNITS OUTSIDE UNIT 7.7 When cutting fibers to length wrap the four feet of fibers of the inside unit around the tray in a counterclockwise direction. Cut the fibers so that the splice section will fit into the splice-protector-holders. Be sure that the fibers are cut and positioned in COLOR CODE ORDER. Prepare the outside unit in the same manner. The first six fibers will be shorter than the last six fibers in the outside unit (See figure 11). The inside unit, the first six fibers will be longer than the last six fibers (this figure is based on a 12-fiber unit design). Place the splice tray cover onto the splice tray making sure that all of the fibers are wrapped inside of the splice tray.

Installation Instructions INS-ACA035 7.8 Prep all trays in the same manner as in (Fig. 12) before any splicing is performed. This may vary due to fiber count configurations. Lay the fibers across their appropriate Splice Protector Holder and then cut the fibers at the mid-point of the Splice Protector Holder. Fig. 12 CUTTING THE FIBERS TO LENGTH OUTSIDE UNIT FIBERS 7-12 OUTSIDE UNIT FIBERS 1-6 CUT FIBERS HERE INSIDE UNIT FIBERS 7-12 8.0 Splicing Fibers When splicing, follow these steps: INSIDE UNIT FIBERS 1-6 CUT FIBERS HERE 8.1 Splicing will be easier if the splice tray is level with the top of the splicer. 8.2 Lay out only enough fiber to cleave and place into the splicer. 8.3 Slide splice protector sleeve over one of the fibers BEFORE STRIPPING, CLEANING, CLEAVING AND LOADING INTO SPLICER. 8.4 After splicing is completed and the splice has been accepted by the splicing technician, slide the splice protector over the spliced area and place in the tube heater. Once the splice protector has cooled and has become rigid, place and center it into splice protector holder in the tray. 8.5 After all of the fibers have been spliced, protected and positioned, make sure that all fibers are stored on the inside of the splice tray. Place the splice tray cover onto the splice tray. Secure the splice tray cover to the splice tray by wrapping both ends of the splice tray with electrical tape. (See Front View, Fig. 12a, on following page). 8.6 If multiple splice trays are present, work only with one splice tray at a time. Make sure that Step 8.5 is completed before continuing to the remaining trays. 8.7 Place the splice tray(s) on the mounting plate bolt. If multiple splice trays are present, be sure to stack all splice tray(s) on the same side of the mounting plate. Place the tension nut on the bolt and tighten it down snug. This will keep the splice tray(s) secured to the mounting plate. www.aflglobal.com or 800-866-7385 10 2011, AFL, all rights reserved. Revision 1, 11.20.14

OPTICAL UNITS ELECTRICAL TAPE TIE-WRAP UNITS OVER FELT TO THE BACK. 8.8 Place felt around the mylar tape on both units and tie-wrap as shown on the Front View in Fig. 12a above. 9.0 Installing Mounting Plate to Splice Box 9.1 Using double-back tape, secure the optical units to the back side of the mounting plate. Tie-wrap the optical units (snug) as shown in Fig. 12b above. 9.2 Coil the optical units in a counter-clockwise direction on to the back side of the mounting plate. Coil just enough of the optical units so that the mounting plate would lie on the ground. (The reason for this is to prevent a tremendous mechanical shock to the optical units in the event that the technician drops the mounting plate while coiling the optical units as he climbs the tower.) 9.3 After coiling as much of the optical units (while on the ground, tie-wrap the units snug, but not too tight), continue to coil the optical units around the back side of the mounting plate about 1 inch from the edge until the splice box has been reached. Remove the duct tape from the top front rim of the splice box. Proceed to coil the small section of optical units in a counter-clockwise direction and by aligning and positioning the mounting plate to the center shaft. NOTE: Coiling the optical units should be done by rotating the mounting plate. This avoids twisting and stressing the fiber units. (See Back View, Fig. 12b, above). 9.4 When all of the slack is coiled and stored behind the mounting plate, align the mounting plate and secure it to the center shaft by placing the spacer on the center shaft and installing the outside retaining clip ring (See Fig. 13).

Installation Instructions INS-ACA035 5.0 Routing of Optical Fibers Fig. 6a Fig. 6b 5.1 Route all of the fibers into the tray by using the following procedure: (36F on Left / 36F on Right) 5.1.1 A length of 6.5 feet of fiber is used in order to complete two full wraps within the splice tray. 5.1.2 Each set of optical fibers should be separated by unit and individually measured and cut to length. EXAMPLE: If cutting the fibers to length within the blue units, one of the two units would be measured from the top left side of the manifold facing down with the other unit being measure from the bottom left side facing up. All fibers should be stacked in sequence with the lowest number being placed on the bottom. Fibers 1-36 are to be placed on the left hand side of the tray with fibers 37-72 being placed on the right. NOTE: Each tray assembly contains eight, twelve fiber manifolds. Of the eight manifolds, only six are used in the splicing process with the remaining two manifolds being placed in the top positions to help secure the fibers within the tray. 6.0 Fiber Splice Sleeves Fig. 7 6.1 AFL recommends using the Fujikura 60 mm (#500065) splice sleeves for this application. 6.1 NOTE: To ensure that the recommended sleeves are being used, all contractors should check the tightness of their splice sleeves within each of the manifolds used. If necessary, a small bead of RTV can be placed and spread evenly over the splice sleeves to help secure them in place. If this method is used, allow a few minutes for the RTV to begin curing so that the manifolds will not stick together within the tray. www.aflglobal.com or 800-866-7385 18 2011, AFL, all rights reserved.

These methods and instructions are intended as guidelines only, as each installation will be influenced by local conditions, customers existing procedures and requirements. Information such as minimum separation and clearance, sag tables, and specific cable data are found in other documents provided by AFL. This information is generally provided to customers based on specific applications of ADSS fiber optic cable, and can be obtained by contacting AFL. Installation equipment or methods not mentioned in this practice are not approved for use with ADSS and its use without specific approval by AFL shall be at the risk of the customer. Please contact your AFL representative with questions about any specific method or for specific equipment recommendations. Methods used for placement of aerial, all dielectric, self-supporting, ADSS fiber optic cable are essentially the same as those used for placing power utility phase conductors. Refer to ANSI/IEEE Std. 524-2003, IEEE Guide to the Installation of Overhead Transmission Line Conductors for additional detail on installation techniques. 2.0 SAFETY ISSUES Crew safety is of the utmost importance when placing any fiber optic cable. When in question, follow the precautions and safety requirements of the respective company, and take no unnecessary risks. When placing ADSS, all precautions and safety requirements of the respective company shall be followed. When required, use of warning signs and traffic warning cones shall clearly define the work area to safely channel the traffic. On streets or highways, always place the cable in the same direction as the traffic flow and use flagmen to control traffic. Page 2 of 24 All Dielectric Self-Supporting Installation Instructions - 2011 Edition
WI-0301 REV. 0 Legacy Document Number: ACS-WI-812 Effective Date: Sep 6, 2013 All crew members should have the appropriate tools and personal protective equipment to properly perform the job. Installation of the cable without the proper equipment may place personnel and the cable at risk. When placing ADSS on active structures, or structures involving power crossings, observe the safety precautions outlined in your company s applicable procedures. When pulling up and tensioning self-supporting cable, observe the same precautions used when pulling up and tensioning metallic phase conductors or any other aerial cables. When aerial lift equipment is used for placing self-supporting cable, all precautions outlined for placing phase conductors, as well as the instructions covering the equipment must be observed. Although ADSS is an all-dielectric cable, some conductivity can result from moisture on the cable and in the surrounding air. As a precaution in high voltage environments, it is recommended that the installed cable and metallic attachment hardware are grounded prior to touching. For cables installed in other situations, the National Electric Safety Code (NESC) should be consulted for recommendations. The cable can be classified as either a fiber optic-supply or fiber optic-communications cable, and meets the requirements for an effectively grounded neutral as defined in NESC rule 230E1. The precautions in the following paragraphs must be observed to assure safety during and after the cable installation. Leakage current can be induced onto ADSS and attachment hardware even when the cable is a relatively long distance from the phase conductors. AFL Telecommunications can calculate the leakage current based upon the cable position relative to the phase conductors and to the ground, the transmission voltage and the surface resistivity of the cable jacket. The cable surface resistivity is dependent on the moisture and contaminants on the cable. A clean, dry cable has a surface resistance of 10 14 Ω/ft and a dirty, wet cable has a surface resistance of 10 6 Ω/ft, therefore, DO NOT INSTALL CABLES ON ACTIVE TOWERS DURING WET ENVIRONMENTAL CONDITIONS. When the cable is too close to the phase conductors, scintillation can occur through the air from phase conductors to the cable. This scintillation from a phase conductor to ADSS cable can occur only when the resistance of the cable sheath to the grounding location is low enough to lower the induced voltage. In the worse case condition, the cable resistance is zero, at which time it will be similar to a grounded metal rod. A grounded rod configured in air has a flashover voltage of 15kV/in. for large gaps. Hence, the safe approach distance to keep the phase conductors away from the ADSS cable can be calculated by: SD = E/15 where, SD = distance (inches), and E is the phase-to-ground voltage (kv). Note: The work rules of the NESC Section 43 and 44 should be used to determine safe approach to live systems. Specific safe approach distance to active phase conductors are defined in the National Electrical Safety Code (NESC) Work Rules sections. The safe approach distance is different for electrical personnel and telecommunications personnel. The values listed in this section should be the minimum safe approach distances to active phase conductors. Page 3 of 24 All Dielectric Self-Supporting Installation Instructions - 2011 Edition
WI-0301 REV. 0 Legacy Document Number: ACS-WI-812 Effective Date: Sep 6, 2013 When splicing ADSS cable during wet/rainy conditions near active high voltage phase conductors, it is advised to ground the cable between the work area and the spans (such as at the attachment hardware). This will prevent dangerous leakage currents and transients from flowing through personnel. In dry weather there is little induced charge on the cable; however as a personnel safety practice, the cable should be grounded between the work area and the spans. During Routine Maintenance: a. Dry Weather Conditions. When the cable is suspended by insulators or on wooden poles, a voltage potential maybe induced in the metal suspension grips and support hardware. To avoid dangerous electrical shock, GROUND THE METAL GRIPS BEFORE TOUCHING. The cable can be touched anywhere when it is dry, because there is little charge induced on the small area that is touched. b. Wet Weather Conditions. When the cable is wet, the resistance to ground is low near the tower or grounded structure, so there is little voltage potential on the metal grips or cable at these points. However, at distances of 10 to 15 feet or further from the metal grips, a voltage potential may exist. To avoid dangerous electrical hazards, GROUND THE CABLE WITHIN 3 TO 5 FEET ON BOTH SIDES OF THE AREA TO BE TOUCHED. Adequate electrical protection must be established at all work sites. The method required, and the equipment used, will be determined by the degree of exposure to electrical hazards and the soil conditions at the site. All metallic equipment, hardware, anchors and structures within such work sites must be common bonded together, and then grounded to assure worker safety. 3.0 CABLE-RELATED PRECAUTIONS Upon receipt of the cable reels, remove all reel lagging and packing material from the reel and inspect the lagging, reel, and outer coils of cable carefully for any shipping damage. Check the inside edges of the reel for any sharp edges of the reel for any sharp edges or obstructions that may have occurred during shipment and could potentially damage the cable sheath, or interfere with turning the reel and the cable deployment. Prior to starting construction, use an optical time domain reflectometer (OTDR) to verify that the cable has not been damaged during shipment. Readings obtained may be useful later for comparison with test acceptance data and as part of a records package that will assist in emergency restoration. ADSS fiber optic cable is very strong and robust. However, care must be taken to assure the cable is not mishandled or installed improperly causing subsequent damage. Ensure that the cable is not kinked or that the minimum bend radius (typically 20 times the cable diameter plus 2 inches for dynamic (installation) conditions, and 10 times the cable diameter for static situations, (such as cable stored in a vault) is not exceeded. Take all precautions that the cable is never crushed or twisted. Any such damage will alter the transmission characteristics of the fiber and may require replacement of that cable section.
