Specifications include, but are not limited to: 1. Service Providers shall provide a minimum of 2 strands (one pair) of fiber. Optionally, vendors may quote additional fibers, incrementally in pairs up to twelve pair. The district will weigh the cost of additional pairs vs the cost differential of advanced optics (DWDM / 40G / 100G) and required equipment. 2. Service Providers shall provide a fiber path route maps detailing the cable routes for the proposed fiber links. 3. Service Providers shall not exceed 40km of total cable length between each site. 4. Preference for geographically diverse and lowest-cost fiber paths. While the district preference is for a ring architecture, vendors may propose additional architectures such as dual-hub and spoke, or a combination of ring and dual-hub. Single hub and spoke is not preferred. 5. Fiber/Cable Type a. Preference for non-dispersion compensated fibers consistently throughout the network. b. Service Providers must identify the fiber type they use in their response and provide specifications for the fiber and cable. c. The Agency anticipates lighting the Service Provider’s fiber with 10GBASE G.694.1 100Ghz DWDM optical modules with LC connectors. d. The fiber connectors and adapters shall be compliant with TIA/EIA 604 e. The fiber connectors shall have an average insertion loss of 0.3 dB or less. Service Providers should provide datasheets for the proposed SC fiber optic connectors and adapters. 6. Link Loss Budget a. Preference for link loss of 12 dB or less as measured using a double - ended loss test at 1310 nm b. Service Providers must identify in their proposal any links where the estimated link loss is estimated to exceed 12 dB. The estimated link loss shall be indicated for any exception. 7. Inside Building Cable Routing a. Intra-building cable routing shall be performed in accordance with all applicable local building codes. When required, the Service Provider must plan a splice point at the building entrance to transition from outdoor cable to indoor cable, or enclose the outdoor cable in metallic conduit or covered metal raceway. 8. Cable Slack for Repair or Relocation a. A small amount of slack cable (15 - 20 feet) shall be neatly stored in each MDF in the event that a cable repair or relocation is required. 9. Site Make Ready Work a. Any trenching and conduit placement from the street to the building entrance point must include all necessary pavement and ground repair . All pavement and other grounds must be returned to its original condition. All installation of cabling, pathways, etc shall be to BICSI specification and the design specifications of The Agency.
