EXHIBIT B Fiber Specifications/Acceptance Testing 1. Fiber Specifications. a. The maximum bi-directional average splice loss shall not exceed 0.15 dB. b. All splices shall be sealed in waterproof splice enclosures. c. Attenuation at 1310 nm = 0.35 dB/km max d. Attenuation at 1550 nm = 0.25 dB/km max e. Connector loss shall not exceed 0.5dB per connector. f. Fiber will meet or exceed Corning Single Mode Fiber SMF-28 Specifications g. Event Reflectivity (Minimum ORL) should not exceed 27 dB. 2. Fiber Acceptance Testing. CITY Contractor will conduct the following tests as part of its Acceptance Test Plan: • Non-destructive Attenuation Tests (End to End) • Optical Time Domain Reflectometer Tests (OTDR) Fiber acceptance testing will be performed to ensure that the fibers will operate within the parameters of the Specifications set forth in this Exhibit B. a. More specifically, fiber acceptance testing will include the following: • Continuity Uniformity Tests: All fibers shall be tested bi-directionally at 1310 nm or 1550 nm, as applicable, with an OTDR; the subsequent traces shall be inspected for end-to end continuity and for uniform attenuation. These traces will be attached to an email or contained on a removable storage drive. • Optical Length: The OTDR will be used to determine the end-to end optical length of the cable. • Splice Loss: Splice loss will be measured bi-directionally with an OTDR using the Splice Loss average method. • End-to-End Loss: Using a light source and a power meter, the bi-directional, connector-to-connector attenuation will be measured for each fiber at 1310 nm and 1550 nm,as applicable. The acceptance average attenuation per kilometer on a per span basis shall be the attenuation set forth by this agreement. a. The end-to-end value as measured with an industry-accepted laser source and power meter should have an attenuation rating of less than or equal to the following: (1) At 1310 nm: (0.35dB/km x km of cable) + 21
