EXHIBIT E METROPOLITAN (LOCAL LOOP) NETWORK FIBER ACCEPTANCE TESTING PROCEDURES AND STANDARDS The intent of this Exhibit is to identify the fiber acceptances testing procedures and standards used -within the Zayo's metropolitan networks. Deviations from these specifications may occur if Zayo acquires a portion of the Zayo System from a third party pursuant to the Agreement. 1. All splices shall be fusion spliced. Mechanical splices are only allowed during temporary restoration and will be replaced with fusion splices. 2. After end-to-end connectivity on the fibers has been completed, bi-directional OTDR span and power meter testing will be completed. Zayo shall perform tests after the fiber cable is installed and the splicing enclosures have been completed and are in their final resting configuration with the cable vault or hand hole covers closed. This ensures that no micro or macro bending problems with the cable or fiber strands will contribute to the loss/attenuation measurements. 3. Power meter tests shall be completed to verify and insure that no fibers have been crossed at any of the splice points within the network. Zayo shall test and record power level readings on all fiber strands in both directions of transmission (bi- directionally) using the 1310 & 1550 nm wavelengths. 4. All OTDR and power meter tests shall be completed as follows: a. All OTDR traces shall be taken from both ends of a section (between adjacent locations) and recorded using the 1310 nm & 1550 nm wavelength. Loss/attenuation measurements for each splice point from both directions shall be taken and recorded. b. The end-to-end loss 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: (0.35 dB/km x km of cable) + (number of connectors x 0.50) + (0.15 x number of splices). (2) At 1550 run: (0.25 dB/km x km of cable) + (number of connectors x 0.50) + (0.15 x number of splices). .c. Zayo's loss/attenuation objective for each fiber optic splice is 0.15 dB when measured in one direction with an OTDR test set (excluding connector loss, which is typically 0.50 dB per mated connector pair). If after three attempts this parameter is not met, the splice will be marked as Out -Of -Spec (OOS) and the Splice will remain provided the average Loss/attenuation value of all splices- on an individual fiber basis shall not exceed 0.15 dB for the entire ring or subsystem. d. For bi-directional OTDR testing, the distance from Location "A" and Location - "Z" shall be recorded for each splice point. The loss/attenuation at each splice point shall be recorded at both wavelengths (1310 nm & 1550 nm) in each 64 • Anoka County Master Fiber IRU 8.14.10
