7 Fibre Routing This joint is suitable for both dual and single fibre working practices and fibre circuits can be routed to any tray within the joint from any cable position. To allow circuits to be routed from one side of the joint to the other, fibre can be routed through the transfer port. Elements are to be routed and stored first, followed by single circuits. Fibres must be routed in number/colour from the lowest start position and store the fibres safely within the trays. Note: the element tubes from COF 200/COF 201 and the 3mm tube from a BF water block are both installed in the same way. Fibre Numbering Colour Scheme 1 Blue 2 Orange 3 Green 4 Red 5 Grey 6 Yellow 7 Brown 8 Violet 9 Black 10 White 11 Pink 12 Turquoise Note: all tubes require collets (I/C 006890). Warnings 1 Spare or dark fibres must be clearly identified and stored on separate trays. 2 Use pen marker No 1 (I/C 129408) to record the fibre, element and cable number on the trays. 3 Fibre must not be stored in the routing area. 4 Take care when routing fibres as existing fibres may be live. 7.1 COF 200/COF 201 Route the element tubes to the nearest/most convenient tube holder. Slide the element support tube 3A over the element tubes down to the cable butt and mark the length to just under the selected tube holder. Remove element support tube 3A, cut to length and re-install over the element tubes. Note: element support tube can be installed onto previously installed cable elements by carefully making a longitudinal cut with scissors. 7.2 Position the element tubes in the selected tube holder and mark the tubes between the two marks that are moulded into the tube holder. Remove from the tube holder and cut the element tubes to these marks. Degrease and clean the fibres ready for storage. 12
7.5 Route the fibre in the groove alongside the trays to the entrance of the required tray. Fibre must be routed in the groove below the hinge of the tray. 7.3 Install split colletts (Item Code 006890) as shown above. Re-install the tubes in the tube holder and slide in a tube holder cover with the slot facing up. Use the lowest position to secure all elements. Note: the tube holder must click into place. 7.6 Store fibre safely beneath the tabs and ensure that it is loosely coiled. Identify on tray. Note: the crossover in the centre of the tray can be used for reversing direction of fibre. 7.4 Different tubes can be put together beneath the same tube holder retainer. Position one or more loose tubes in the tubeholder and slide the tube holder retainer with the slot facing up in the lowest possible cavity above the loose tube(s). The tube holder retainer must click into place. 7.7 Alternative Routing Fibres can be routed to the other side of the joint through transfer port as shown in the diagram. Route in number/colour order from the lowest position and store fibres safely within trays. Note: fibres can be routed either side of the closure using the transfer port. Installation tip: use a short length of portex tube (or similar) as a fibre guide and remove when finished. 13
7.8 To allow full flexibility for routing purposes, fibres can be routed left to right and also right to left. 7.9 For the storage of fibre, route from the tube holders up to the splicing trays and store as required (SE tray shown as an example). Identify on tray. 7.10 Blown Fibre Routing Route the blown fibre tube to the nearest/most convenient tube holder. Install water block (I/C 006848) and transparent tubing (I/C 006849). Position in tube holder and mark the tubes between the two marks that are moulded into the tube holder. Remove from tube holder and cut tubing from this mark. Strip bundle and clean the fibres ready for storage. 7.11 Blown Fibre Distribution Route the required Distribution blown fibre to the required Primary input tray. Prepare fibre for jointing and store safely on tray when completed. Note: generally route Distribution fibres to the right-hand side of the tray. Alternative routing can be used, as shown in previous examples. 14
9 Closing the closure Ensure all fibres are identified on trays correctly. 7.12 Splice Holder positions 8 Cable grounding/shielding 9.1 Install tray lids including fibre guiding pins and tube holder covers on top trays. 8.1 All cable grounding/shielding wires must be connected to the nylon bolt along with the wire from the pressure relief valve, store safely in the base of the closure. Note: Moisture barrier connection is NOT required for Blown Fibre Tubing. 9.2 Replace the tray support onto the routing block cover and install over the routing block. Secure the hook and loop fasteners. Check position of O ring, place dome over closure and install clamp. Note: the legs on the clamp lever can be used to close the clamp. 15
