User Guide E2O6CMRXP-1T9 drop fiber leg preparation E2O Drop is a F677TSVRXP drop cable combined with a 900 μm tight buffered, bend-insensitive, singlemode fiber. It is an indoor/outdoor cable with a CMR rating for use in riser applications. E2O Drop has an installation load limit of 250 pounds and a residual load of 75 pounds when the fiber and coaxial cable are joined. However, when the fiber is separated, the fiber leg has a load limit of 33 pounds and a residual load of 10 pounds. Installation load is defined as a short-term load that can be seen during installation, which, if exceeded, results in impairments to optical performance that would be permanent. Residual load is defined as a long-term load that remains with the cable post installation, which, if exceeded, results in impairments to optical performance that would be permanent. To provide perspective the normal tensile force, coaxial drop cable being pulled off a reel and through a section of conduit 200 feet long is 16 pounds of force or less. When used in riser applications, the cable has a maximum vertical rise limit of 1640 feet (500 meters). E2O6CMRXP-1T9 drop fiber leg preparation is performed using a jacket slitter and fiber stripper while following the simple process that is outlined here. Figure 1 commscope.com 1
The E2O6CMRXP-1T9 Drop fiber leg contains a 1.6 mm simplex fiber cable as shown in Figure 2. To access this cable, the over jacket that is used to couple the fiber leg to the coaxial cable must be removed. Figure 2 To remove the over jacket, a cable slit tool is used to slit open the over jacket. The tool has two opposing blades (Figure 3) to simultaneously slit the over jacket in two halves. Miller (Ripley) Tools www.ripley-tools.com 800-528-8665 400 Series Slitter for E2O Drop Part No.: 80964 Figure 3 Place the fiber leg into the cable slit tool, orienting the yellow tracer stripe so it faces towards the top of the tool with the tail end of the fiber towards the yellow handles as shown in Figure 4. Grasp the tool in one hand by placing the thumb and ring finger on the sides of the blocks and placing the index and middle finger on the back of the blocks; be certain to allow the fiber to pass between the index and middle finger without touching. Grasp the cable behind the tool in the other. With the fingers, apply a light amount of pressure on the blocks of the slitting tool; begin pulling the tool towards the end of the cable in a slow and steady motion while firmly holding the cable in the other hand. If too much pressure is applied, the cable jacket may stretch rather than slit; this will likely result in damage to the fiber. Figure 4 commscope.com 2
After completing the slit, carefully pull at the over jacket on the end of the cable to begin the separation (Figure 5). Figure 5 The two halves of the over jacket should pull apart like a banana peel (Figure 6). Figure 6 Carefully trim away the two halves of the over jacket from the cable with a pair of cutters such as scissors or sharp diagonal side cutters (Figure 7). Figure 7 commscope.com 3
The next step is to strip off the required amount of 1.6 mm simplex jacket from the fiber. Measure the length to be removed and mark it with some type of a marker. Use the large hole in a tri-hole fiberoptic stripper (Figure 8). This will expose the aramid yarns (yellow), two water-blocking cords (white), and the 900 μm fiber (blue). Figure 8 Miller (Ripley) Tools www.ripley-tools.com 800-528-8665 Tri-Hole Fiber-Optic Stripper FO-103-T-250-J Part No.: 80677 Figure 9 If necessary, trim the aramid yarns and water-blocking cords. Use the 900 μm stripping hole on the tri-hole fiber-optic stripper to strip off the 900 μm tight buffering to expose the needed length of the 250 μm fiber (Figure 10). Figure 10 The 250 μm fiber can now be stripped and prepared for slicing or connectorization. Figure 11 commscope.com 4
