Bore Tech Utilities & Maintenance Splicina, Enclosures and Patch Panels RFP 22-04-01 Fiber-optic cables will be installed without splices except where specifically allowed on the plans or described in these special conditions. The single -mode fiber-optic cables used for distribution will be spliced in pull boxes as shown on the plans or at aerial slack locations as shown on drawings. When splicing into a distribution cable, only those fibers associated with the count transferring onto the distribution cable will be severed. All other fibers shall remain intact. As the job progresses Engineer may allow additional splices between these specified locations. At no point will fiber cables, be severed out of the convenience of our installation. Splices will only be performed at planned locations. Situations where this cannot be accomplished will require be pre -approval prior to adding any additional splices to the network. Optical fibers shall be spliced using the fusion splice method and the insertion loss shall not exceed 0.20 dB of loss per splice when tested using a bi-directional average. All splice cases, trays and fiber termination panels will be properly labeled to identify cable size, fiber count and routing of each fiber strand. All closures shall include all necessary hardware items to support the cable adjacent to the closure. The fiber organizer trays will be supplied as part of the Splice Case Closure. Cable closures will be installed in accordance with the manufacturers instructions. Splicing will be performed in accordance with RUS Splicing Standard Bulletin 1753F- 401 (PC -2). Field splicing is permitted for the following: • Connection of cable reel sections. • Connection of a mainline service distribution cable to a service.drop cable or a breakout cable. • Connection of service drop cable or breakout cable to an optical fiber pigtail at cabinets or the patch panels. • Connection of the backbone cable to an optical fiber pigtail at a hub patch panel. We will not exceed the maximum number of field splices permitted indicated in the plans. Completed splices will be placed in a splice tray. The splice tray will then be placed in a watertight splice enclosure. Field splices will be conducted only at locations as shown in the plans as an approved splice location. All splices will be protected with a thermal shrink sleeve. All fibers will be labeled in the splice tray with permanent vinyl markers. Pigtail ends will also be labeled to identify the destination of the fiber. Pigtail ends will be labeled to identify the destination of the fiber. All splice cases used on this project will be CommScope FOSC 450 Gel sealed fiber- optic splice closure or approved equal. The following sizes shall be used: • FOSC 4508 — Holds up to 144 fiber splices • FOSC 450D — Holds up to 576 fiber splices 11
