3 General precautions 3.1 3.2 3.3 Do not use damaged sleeve nor trim heat-shrinkable sleeve before installation. The FOSC-400D5 closures can be installed at temperatures between -1°C and +45°C. Generators used should have enough capacity for the hot air gun utilisation. Optical fiber infrastructure network elements may contain end of optical fiber attached to the optical output when the device is operational. Laser radiation can seriously damage your eyesight. Please follow your local safety guidelines.
4.4 Slide the cables through the opened oval port. Prepare cables as described in section 5 (cable preparation). 5 Cable preparation 5.1 Remove the cable sheath (and shield if present) over a length as required by locally approved practice (e.g. 1,5 meters). Clean filling compound from fiber tubes and cut central strength member at a distance of 230 mm from outer jacket. Note. For the ribbon cable the maximum striplength is 1.5 m. Strength member Buffer tubes 5.
5.4 Align cable ring cuts with edge of base. Slide strength members into clamps and tighten. Cut away the excess length of strength member. 5.5 If required, connect shield continuity wire of both cables with shield continuity clip. Talk pairs, if present, will be connected together according to the local procedures. 6 Sealing of oval outlet 6.1 Thoroughly clean oval port and cable sheath with the cleaning tissue over a distance of 100 mm from the edge of the port. 6.
6.3 Place oval seal over the oval port and cable. Mark the sleeve length onto the cable. 6.4 Match the blue line of the aluminium cable protection foil with the marks on the cables. Wrap aluminium cable protection foil around cable. 6.5 Slide the oval cable seal over the oval port. Install the branch-off clip. Check that the heat-shrinkable sleeve butts up against the FOSC-base and the branch-off clip is completely inserted. Tape the two cables together. 6.
6.7 Shrink down the end of the sleeve on the cable side. Heat until the sleeve shrinks down on the cables and take care that the green thermo-indicating paint is converted to black. Postheat the clip on both sides till the adhesive shows a proper flow on the clip between the two cables. Wait until the sleeve is cool to the touch before moving the cables. 7 Positioning the transportation tubes and fibers 7.1 Lift the top tray to expose the bottom tray, which should be filled first.
7.5 Secure the transportation tubes to the tray with tie wraps as shown. 7.6 Arrange the fiber around the tray for storage until the fiber is to be spliced. 7.7 When all fibers to be stored in this tray have been arranged, replace the tray cover. 7.8 Repeat steps 7.1 through 7.7 for each tray until all fiber has been stored in a tray. 8 Add or remove splices trays 8.
9.2 Place appropriate intertray identification markers on a transportation tube. (Intertray ID markers are marked “1TO” through “8TO” and “1” through “8”, to indicate which tray the jumper came from and which tray it is going to.) 9.3 Guide the desired fibers through the marked transportation tube (now called the intertray jumper). 9.4 Secure one end of the intertray jumpers to the originazing splice tray with two tie wraps.
10.6 Secure all trays to the bottom tray bracket with the Velcro strap as shown. 11 Velcro strap Splicing of ribbon cable 11.1 Identify each ribbon. Split each ribbon into individual fibers. Follow the manufacturer’s recommendations for the splitting ribbons. Splice and organise the fibers as explained in section 10. Ribbon 12 Dome installation 12.1 Open and remove the desiccant bag from its package and place the desiccant bag on the upper tray.
12.3 Place the dome carefully over the trays onto the base. Put the clamp around the base/dome interface. Close the clamp. 13 13.1 Re-entry Remove the clamp. 13.2 Remove carefully the dome and the sealing ring. Keep the sealing ring and seal area of the closure free of dirt. (If needed rinse with clear water). 13.3 The dome may be reinstalled by following the procedure as described in section 9. Replace the 75 grams of desiccant. The sealing ring has also to be replaced if damaged.
14.2 Remove any dirt, mud or other contaminants from the cable sheath for approximately 2 meters with a clean cloth. Take the cable seal sleeve from the kit FOSC-B/DCSEAL-1-NT and slide it over the cable. The noncoated edge of the sleeve and the arrows should be pointed to the base of the closure. 14.3 Prepare the cable as outlined in section 5 “Cable preparation”. 14.4 Slide the prepared cable through the opened entry port and install the transportation tubes described in section 5. 14.
14.7 Abrade port and cable sheath circumferentially on the cleaned area with the abrasive strip. Remove any abraded material with a clean cloth. 14.8 Place cable seal over the drop outlet of FOSC base. When cable seal butts against the base, mark the sleeve length on cable sheath. 14.9 Match the blue line of the aluminium cable protection foil with the marks on the cables. Wrap the aluminium cable protection foil around cable. 14.
14.11 Shrink down the end of the sleeve on the cable side. Heat till the sleeve shrinks down onto the cable and the green thermo-indicating paint is converted to black. A ring of red adhesive should be visible at the cable on the end of the sleeve. Wait until the sleeve is cool to the touch before moving the cables. 14.13 Re-install the sealing ring, the dome and the clamp (see section 12). 15 Additional cable installation 15.1 For each added cable use a FOSC-B/D-CSEAL-1-NT.
