<br />City of Sunny Isles Beach |Request for Proposal No. 22-04-01 36 <br /> <br />cable will not experience a measurable increase in attenuation when subjected to the rated residual <br />tensile load, 890 N (200 lbf). The repeatability of the measurement system is typically ± 0.05 dB or less. <br />The cable shall be capable of withstanding a bending radius of 15 times the cable diameter under tensile <br />loading and 10 times the cable diameter under a no-load condition <br />4. Splicing <br />4.1 General Guidelines <br />This section describes minimum requirements for splicing and connecting of the specified optical fiber <br />cables. <br />Fiber-optic cable shall be installed without splices except where specifically allowed on the plans or <br />described in these special conditions. The single-mode fiber-optic cables used for distribution shall be <br />spliced in pull boxes as shown on the plans or at aerial slack locations as shown on drawings. When <br />splicing into a distribution cable, only those fibers associated with the count transferring onto the <br />distribution cable shall be severed. All other fibers shall remain intact. The Engineer may allow additional <br />splices between these specified locations. <br />At no point shall cables be severed out of the convenience of the installation contractor. Splices shall only <br />be performed at planned locations. Any situation where this can be accomplished shall be pre-approved <br />prior to adding any additional splices to the network. <br />4.2 Labeling <br />All splice cases, trays and fiber termination panels shall be properly labeled as to identify cable size, fiber <br />count and routing of each fiber strand. <br />4.3 Splicing <br />Optical fibers shall be spliced using the fusion splice method and the insertion loss shall not exceed 0.20 <br />dB of loss per splice when tested using a bi-directional average. <br />All closures shall include all necessary hardware items to support the cable adjacent to the closure and <br />to terminate the lashing wire (if aerial). The fiber organizer trays shall be supplied as part of the Splice <br />Case Closure. <br />Cable closures shall be installed in accordance with the manufacturer’s instructions. Splicing shall be <br />performed in accordance with RUS Splicing Standard Bulletin 1753F-401 (PC-2).
