City of Sunny Isles Beach |Request for Proposal No. 22-04-01 39 Optical fiber connectors shall satisfy all interface parameters of equipment components as may be defined by the transmission equipment specifications. All optical fiber connector assemblies shall be machine angle polished for low back-reflection and low insertion losses at both 1310 nm and 1550 nm wavelengths. Single-mode pigtails shall be provided with factory pre-connectorized single-mode connectors of the "LC Angle-PC" type. Connectors shall have maximum insertion loss of 0.5 dB or better. Connectors shall have a composite barrel with a “push-pull” connection design, ceramic (zirconia) ferrule. Each connector shall be capable of 200 repeated matings with a total maximum additional increase in insertion loss after 200 matings limited to 0.30 dB. Each connector shall have a return loss (back reflection) equal to or better than .50 dB. All connectors shall be factory-assembled and tested. There shall be no fabrication of connectors in the field. All unmated connectors shall have protective caps installed. 4.8 Couplers Couplers shall be made of nickel-plated zinc or a glass reinforced polymer that is consistent with the material forming the associated lC connector body. The design mechanism for mounting the coupler to the connector panel may be flanged or threaded but shall coincide with the connector panel punch-outs. All coupler sleeves shall be ceramic of the split clamshell or clover leaf design. The temperature operating range for couplers shall be the same as that specified for the SC connectors. 4.9 Pigtails Pigtails shall be of simplex (one fiber) construction, in 900 µm tight-buffer form, surrounded by Aramid for strength, with a connector on one end. The outer jacket shall be yellow PVC with a nominal diameter of 3 mm, marked with the manufacturer’s identification information. All pigtails shall be of adequate length for the intended connection purpose, but not less than two meters in length. Pigtails installed in conduit shall follow the installation procedures outlined for fiber-optic cables, except that the pulling tension shall not exceed 500 N (110 lbf.). 4.10 Fiber Termination Panels Fiber terminations shall be housed in a rack mounted fiber termination panel, sized appropriately for the cable size installed. All materials including fiber panel housing, pigtails, splice cassettes, trays, connector panels and all other materials required for a complete working system shall be provided by the Contractors and shall be included in Contractor pricing.
