NC-1000 FIBRE OPTIC CROSS-CONNECTION SYSTEM INSTALLATION MANUAL 1. General In optical distribution frames (ODFs) optical fibre cables are terminated and connected to other cables and equipment. The number of cables coming to and leaving from an ODF may be very high depending on the type and purpose of the ODF. Therefore it is very important that the ODF including all cable installations has been designed, planned and installed with appropriate skill and knowledge. NC-1000 fibre optic cross-connection system is an ODF that is designed according to the most critical requirements to reach a solution with easy installation, good functionality and high reliability. All important aspects are taken into account regarding cable assembly, fibre connections as well as addition of new cables and modifications. Modular and clear design, usage of pre-assembled patch panels and smart fibre management provide easy installation, changes, expansions and other maintenance practices during the entire lifetime of the system. The main features of NC-1000 are: high fibre capacity excellent fibre management modular and clear design access from the front side pre-assembled patch panels easy to install, upgrade and maintain dimensions according to ETSI standard patch cords can be guided directly between NC-1000 frames fibre splices may be located inside or outside of the frame cables can come to the frame either from bottom or from top NC-1000 technical data dimensions 600 x 300 x 2200 mm or 600 x 300 x 2000 mm capacity for up to 960 or 864 fibres (depending on the height of the frame) standard construction: turning inner frame, fibre and cable guides in inner frame and rack, front and back doors and side covers NC-1000 patch panels connector alternatives SC/UPC, SC/APC and LC/UPC includes the mounting frame are delivered pre-assembled with the defined length of pigtail cable suitable for both indoor and outdoor usage number of fibres in the pigtail cable is 24 or 48 the cable length is 5, 15, 25 and 50 m or it can be specified by the customer (A m) delivered with a connection card containing a coupling order and a colour coding system of the pigtail cable also available as 1x16, 1x32 and 1x64 splitter modules 4 5

3. Mounting of the frame NC-1000 frames are delivered separately protected with their own transportation pallet. In the installation site the frame is shifted to its place and fastened to the floor. Before fastening the frame shall be adjusted directly from its adjusting feets. If necessary, the frame can be also fastened to the wall from the top with an optional wall mounting kit. 4. Earthing of the frame If outdoor cables including metallic elements are brought to the frame, the frame shall earthed. Make the earthing by connecting the frame to the equipotential or earthing terminal of the equipment room by using min. 16 mm2 copper wire. Adjust the earthing bar of the frame to the suitable height and connect the copper wire to the bar. 5. Termination of outdoor cables to NC-1000 frame There are two principle ways of outdoor cable termination: 1. 2. Outdoor cables are jointed to pigtail cables within the NC-1000 frame. Outdoor cables are jointed to pigtail cables outside the NC-1000 frame within a joint closure or a splice cabinet. These termination methods are handled separately in the following chapters. 5.1 Termination of outdoor cables to pigtail cables within the NC-1000 frame 5.1.1 Installation of the splice tray holder Take the splice tray holder with its mounting accessories from its package and turn it in the right way for mounting to the inner frame. Install the basket nuts of the splice tray holder to the followig mounting places of the inner frame: upper nuts: 43 cm from the bottom of the inner fame lower nuts: 23 cm from the bottom of the inner fame Fix the splice tray holder with its screws to the inner frame. 43 cm 23 cm 8 9

5.1.2 Bringing cable to the frame Either the top entry or the bottom entry can be used. Cables are brought to the frame outside of the back side where they are earthed if necessary and from where the fibres are brought to the inner frame and to the splice trays in their protection tubes. It is worth of noting that the cables are not fixed permanently to the frame until they have been spliced. Cables are brought to the frame as follows: Release the locking of the inner frame from its bottom and turn it out as much as it goes. Draw the cable ends through the frame below its lowes fixing plate. Draw the cable ends enough out from the frame over their stripping lenght. The stripping length is about 250 cm. Measure about 250 cm stripping lengths of the cables starting from the sheath removal points and cut away the extra lenghts. Remove all protective layers over the fibre tubes. Separate the fibre tubes and the possible fillers from each other. Cut the central element and the possible fillers at the point where the sheath has been cut. Note, if the cable has metallic central element cut it to the length of about 20 cm. Straighten the fibre tubes by using a hot air blower or hot water. If you use a hot air blower, be careful that the fibre tubes dont t get too hot. Connect the connector of the earthing conductor to the possible aluminium laminate or corrugated steel tape. Protect the connection point with an insulating tape. 5.1.3.2 Central loose tube cable Expose the strength elements on both sides of the cable and turn them up to the sheath removal point marked before. Cut them to the length of about 20 cm and bend them on both sides. In the case of a cable with aluminium laminate or corrugated steel tape remove the sheath and other protective layers up o the distance of 50 mm from the sheath removal point. Remove the cable sheath in several parts. In the case of non-metallic cable remove the sheath and protective layers up to the sheath removal point. Remove the sheath in several parts. Remove the sheath from the possible aluminium laminate or corrugated steel tape with a hot air blower and pliers. Use e.g. a steel brush or a knife to remove also the possible plastic coating from the laminate or steel tape in order to ensure the electrical contact for earthing. In the case of metallic strength elemens turn them to the same side of the cable and then at the distance of about 30 mm from the cable towards the cable end. Try to get them as straigth as possible and also near each other that they can be easily guided to the earthing connector. Cut them to the same length as the aluminium laminate or corrugated steel tape. 5.1.3 Preparation and earthing of cables Remove the cable sheaths starting from the sheath removal marks. Prepare and earth the cables according to the instructions of the cable supplier. Two examples are described in the chapters 4.1.3.1 and 4.1.3.2. It should be noted that these are only examples. In every case the instructions of the cable supplier shall be carefully followed. 5.1.3.1 Stranded loose tube cables Cut the cable sheath from the sheath removal point marked before. Remove the cable sheath about 10 cm from the cable end and find the rip cords. Split the cable sheath with rip cords to the sheath removal point and about 30 mm over it. Cut the parts of the cable sheath from the sheath removal point. 10 Cut the central tube at the distance of 30 mm from the aluminium laminate or steel tape and in a case of non-metallic cable at the distance of 30 mm from the cable sheath. Cut the central tube by making first a scratch around the tube and then bending the tube carefully at the both sides until it breaks. Take a hold from the fibres with fingers and pull the central tube away. 11

Clean the fibres from the filling compound. Push the fan-out part of the installation kit (accessory) over the central tube and at the same time guide the fibre bundles along their own slots of the fan-out part. Fasten the fan-out part with the clamp to the end of the central tube. If the fastening is not tight, use the small adjusting parts of the kit under the clamp. Draw the bundled fibres into the protection tubes of the installation kit by using the pulling wire included the kit. The minimum length of the tubes is 110 cm. Push the protection tubes to the slots of the fan-out part and guide the fibres at the same time directly from the central tube to the protection tubes. Mark the ends of the protection tubes with numbers 1,2, 5.1.4 Fibre entry to the splice tray Remove the cover of the splice tray Measure the fibre lenghts to the splice tray. If using Nestor NC-48 splice tray the fibre lengths shall be about 120 cm. Bring the ends of the fibre tubes to the left side of the splice tray (seen from the top) and put them parallel so that the outermost tube is the first and innermost tube the last tube. Fix the tubes with nylon ties. If you are terminating stranded loose tube cable cut the tubes about 25 mm from the fixing point and clean the tubes from the filling compound. If you are using Nestor NC-48 splice tray, loop the fibres going to the two uppermost splice holders one full turn around the tray and then to their splice holders from the left. The fibres going to two lowest splice holders loop fibres first to other side of the tray from the halfway of the tray, then one full turn around the tray and finally to their own splice holders from the right, see the picture below. Make the appropriate markings on the splice tray. Reattach the cover to the splice tray. 5.1.5 Installation of the splice trays to the splice tray holder Draw the cable backwards to the back side of the frame so much that the cable sheath is outside of the frame. Fix the cable temporarily to the frame. Install the splice tray into its appropriate position for waiting the splicing process. Guide the fibre tubes below the splice trays on the hinge side of the inner frame to the back of the frame. The fibre tubes shall be positioned considering the following: Bending radius of fibres Movement of the inner frame Possibility to remove each splice tray separately from the splice tray holder 5.1.6 Installation of NC-1000 patch panel Open the panel package and lift the panel out from the package with its pigtail cable. Take the basket nuts from the accessory kit and mount them to the right places of the inner frame. Install the first panel of the frame into the highest place of the inner frame and the next panels under the earlier panels. Pull the panel frame out from the panel and fasten it to the inner frame from its lowest fixing holes. Loop the fibres to the splice tray. Loop each fibre bundle one full turn on the tray and take each fibre bundle to its own splice holder from the left side Cut away the extra lengths of fibres. 12 13

Open the pigtail cable loop and straighten it. Mark the end of the pigtail cable by the identification number of the panel. Push the pigtail cable through the panel frame and guide it to the management hooks in the right side of the inner frame. Do not fix the cable to the loops leave it as loose as possible. Push the panels separately to their places and lock them with finger screws. 14 15

5.1.7 Bringing of pigtail cables for splicing Bring the pigtail cable to its splice tray loosely below the splice tray and from the front side (seen from the front). Make a cutting marks on the cable to such lengths that the sheath length on the splice tray is about 30 mm and the fibre length is at least 110 cm. If using Nestor NC-48 splice tray the fibre lengths shall be about 120 cm. Cut away the extra length from the pigtail cable. Remove the splice tray from the splice tray holder and set it on the splicing table. 5.1.8 Construction, colour coding and the main properties of the pigtail cable The construction and materials of the pigtail cable is described in the picture below. The colour coding system of the pigtail cable is as follows: Fibre tubes: - 24 fibre cable: blue, red - 48 fibre cable: blue, white, yellow, red Fibres: No. 1 blue No. 7 red No. 2 orange No. 8 black No. 3 green No. 9 yellow No. 4 brown No. 10 violet No. 5 grey No. 11 pink No. 6 white No. 12 aqua (turquoise) The main installation properties of the pigtail cable are as follows: Bending radius: min. 120 mm Pulling force: 1000 N Temperature range - Installation: min. -15 - +70 C - Operation: -40 - +70 C 5.1.9 Preparing the pigtail cable for splicing Remove the pigtail cable from the management hooks of the inner frame. Cut the sheath at the point of the cutting mark. Remove the sheath at the length of about 10 cm from the cable end and find the rip cord. Split the cable sheath by using the rip cord and remove the sheath. Cut all the binding yarns, tapes, fillers and the central element at the point where the cable sheath was cut. Loose buffer tube with 12 colour coded singlemode fibres and filling compound. Dry cable core. Central element (FRP) Filler Swellable tape Rip cord Black UV-resistant outer jacket, FRNC, od. 7,5 mm Fasten the end of the cable sheath with nylon ties to the side of the splice tray which is opposite to the side where the fibre tubes of the outdoor cable are fastened. Cut the fibre tubes at the distance of about 10 cm from the point where the sheath was cut and clean the fibres from the filling compound. Note. Try first the stripping of the fibre tubes before the actual work to make sure that you have a suitable stripping tool and the tool has the right adjustments. A wrong tool or a wrong adjustments of the tool can cause damages or even cut the fibres. 16 17

Loop the fibres on the splice tray. Loop each fibre bundle one full turn on the tray and take each fibre bundle to its own splice holder from the right side. Cut away the extra lengths of fibres. If you are using Nestor NC-48 splice tray, loop the fibres going to the two uppermost splice holders one full turn around the tray and then to their splice holders from the right. The fibres going to two lowest splice holders loop first to other side of the tray from the halfway of the tray, then one full turn around the tray and finally to their own splice holders from the left, see the picture below. 5.1.10 Splicing of fibres Take the fibre bundles out from the splice holders and place them on both sides of the splice tray in their order. Splice the fibres of the outdoor cable to the fibres of the pigtail cables bundle by bundle with a fusion splicer. Loop the spliced fibres on the splice tray and place the fibre protection sleeves to the holders according to the fibre order. Take care in looping the fibres that you don t leave the fibres under their minimum bending radius (min. 40 mm). When all the fibres have been spliced check still that the installation of all the fibres on splice tray has been made properly. In the following pictures there are examples of the splice trays after all fibres have been spliced. Fasten the cover of the splice tray. Mount the splice tray into its position in the splice tray holder. 5.1.11 Fastening and earthing of cables Place the outdoor cables after splicing in the backside of the frame to their right positions and fasten them to the fixing plates with nylon ties. The fastening and positioning should take into account the possibility of adding new cables in the future. Connect the metallic elements of the cables to the earthing bar of the frame. In the following picture the fibres have been prepared for splicing by using an alternative splice tray LT-48. 5.1.12 Fastening of the fibre tubes Guide and manage the fibre tubes leaving the splice trays from the hinge side of the inner frame to the back of the frame. Loop and bundle the fibre tubes and fasten the bundles to the fixing plates in the back of the frame. As fastening the tubes note the movement of the inner frame. E.g do not fasten the tubes to the lowest fixing plate because at this place the tubes shall have a possibility for slight movements. If necessary the fibre tubes at the back side of the frame can be protected with e.g. a spiral type protection tube. 18 19

5.1.13 Finishing the termination Close the inner frame to its normal position and fix it with the lock that is on the bottom of the frame. Check still that the fibre tubes run from splice trays to the back of the frame in a well managed way and are not subject to pressure, sharp bendings or any other risks. 5.2 Termination of cables when outdoor cables are spliced to pigtail cables outside the NC-1000 frame Outdoor cables can be spliced to pigtail cables outside of the NC-1000 frame in a splice cabinet or joint closure that can be inside or outside of the building. If the splices are outdoor, the pigtail cables have to be brought to these splice points in duct pipes, not directly in the ground because the construction of the pigtail cables does not withstand the direct installation in the ground. In this chapter it is handled more exactly only the points that differ from the working steps described in the chapter 4.1. 5.2.1 Bringing the outdoor cables to the splicing point Bring the outdoor cables to the point (frame, rack, cabinet or closure) where the splicing will be made. Measure the stripping lengths of the cables and cut away the extra lengths. Note that the fibre lengths on the splice trays shall be at least 110 cm. If using Nestor NC-48 splice tray the fibre lengths shall be about 120 cm. Prepare the cables for splicing as described in the chapter 4.1.3. Fasten and earth the cables. Bring the fibres to the splice trays as described in the chapter 4.1.4. In the following picture fibres of the outdoor cable have been brought to Nestor NC-48 splice tray. Make the appropriate markings on the splice tray. Place the splice trays to their positions for waiting the splicing process. 5.2.2 Installation of the NC-1000 patch panel Release the locking of the inner frame from its bottom and turn it out as much as it goes. If the pigtail lengths are not long (less than 25 m) you can do directly the working steps as described in the chapter 4.1.6. Note. If the pigtail cables are long or rather long (over 15 m) they are quite troublesome to straigthen or handle near the frame and especially in the case of many pigtail cables. In these cases the installation of the panels can be made on the alternative way as follows: Loosen the loops of the pigtail cables near the panels about 2 m. Take the cable loops one by one under the lowest fixing plate to the back side of the frame and bring the panel through the inner frame to the front side of the frame. Lift the panel near its right position to the front of the inner frame and at the same time lift the panel frame to its position and fasten it to the frame from its lower fixing holes. Push the panel to its position and lock it with two finger screws. 20 21

5.2.3 Bringing the pigtail cables from the NC-1000 frame Guide the ends of the pigtail cables from the lower part of the inner frame and bring them outside the frame below the lowest fixing plate and on the hinge side of the inner frame. Note. Do not fasten the cables to the lowest fixing plate because at this place the cables shall have a possibility for slight movements. If the pigtail cables are routed from the frame downwards under the floor, they are looped behind the frame in such a away that the cables are first brought upwards and then downwards on the right side of the frame (seen from the front) and towards the floor. Cables are bundled and fastened to the fixing plates of the frame. If the pigtail cables are routed from the frame upwards e.g. to the cable shelf, make first a small loop to the left (seen from the front) and fasten cables to the fixing plates of the frame. As routing and fastening the pigtail cables note the bending radius of the cables and the movement of the inner frame. 5.2.4 Finishing the termination in the NC-1000 frame Close the inner frame to its normal position and fix it with the lock that is on the bottom of the frame. Check still that the pigtail cables run from the inner frame to the back of the frame in a well managed way and are not subject to pressure, sharp bendings or any other risks. 5.2.5 Bringing the pigtail cables to the splicing point Bring the pigtail cables to the splice cabinet or joint closure. Measure the pigtail cables so that the sheath length on the splice tray is about 30 mm and the fibre length is at least 110 cm. If using Nestor NC-48 splice tray the fibre lengths shall be about 120 cm. Make the cutting marks on the cables and cut away the extra lengths Remove the first splice tray from its holder and set it on the splicing table. 5.2.6 Construction, colour coding and the main properties of the pigtail cable See the chapter 4.1.8 5.2.7 Preparing pigtail cable for splicing See the chapter 4.1.9 22 23

5.2.8 Splicing of fibres See the chapter 4.1.10 In the pictures below the fibres of the outdoor cables have been spliced to the fibres of the pigtail cables as using Nestor NC-48 splice tray, upper picture or alternative splice tray LT- 48, lower picture. 24 25

6. The installations of the patch cords 6.1 Patch cord installations into the NC-1000 patch panels Bring the patch cords directly to the patch panels without threading through any fibre guides and connect them to the adapters after cleaning (using e.g. a cleaning cassette) After connections guide the patch cords to the right or left to the cabling space of the frame according to the instructions in the chapters 5.2 and 5.3. If you have to make or change connections in fully loaded patch panels, the handling of the connectors and specially disconnecting of the connectors can be quite difficult. For these cases Nestor Cables can deliver special tools for handling very common SC type connectors, product code LV1256, see pictures below. 6.2 Patch cords inside the NC-1000 frame Take the patch cords to the right side of the turnable inner frame. Guide the patch cords through the right side guides of the panels and to the front part of the cabling space of the inner frame. Bring the patch cord loops in the cabling space of the inner frame around the nearest guide to keep them in order. The following installation cases are described in the next chapters: Patch cord installations into the NC-1000 patch panels Patch cord installations inside the NC-1000 frame between patch panels Patch cord installations between the NC-1000 frame and equipment racks Patch cord installations between the NC-1000 frames 26 27

If the patch cords are too long to be stored in the cabling space of the inner frame, guide all extra patch cord lenghts to the cabling space on the left side of the frame and further to the bottom of the frame, if needed. The bottom of the frame works as a storage for patch cords. Guide all extra patch cord lengths to the cabling space on the left side of the frame and further to the bottom of the frame, if needed. The bottom of the frame works as a storage for patch cords, see the earlier chapter. Take care of the appropriate protection of the cabling between racks. If the patch cords are thin single fibre cords or zipcords, it is recommendable to place them to e.g. fibre optic shelfs that have been developed for these purposes. 6.4 Patch cords between the NC-1000 frames Patch cords can be brought from one frame to another directly through the basements of the NC-1000 frames that work also as cabling conduits between the frames. If the NC-1000 frames are placed side by side, the small hatches between the frames shall be removed before fastening the new frame against the older one. When the NC-1000 frames are side by side, patch cords can be brought from one frame to another through those openings between the frames. 6.3 Patch cords between the NC-1000 frame and equipment racks Bring the patch cords to the left side of the patch panels and to the cabling space of the frame. Bring the patch cords first in the cabling space of the frame downwards at the right side of the guides in the back of the frame. Turn the patch cords to the left side of cabling space and further upwards along the back of the frame and through the opening at the top of the frame. The appropriate turning point depends on the lengths of the patch cords. If the NC-1000 frames are situated back to back, patch cords can be brought from one frame to another directly through the openings of the bottom plates in the NC-1000 frames. 28 29
