.e e 2. The OTDR test will be used to determine the quaiity of the fiber link along its length. A capable OTDR must be used to detect events on the fiber. There are two types of events: reflective and non-reflective. These events must be marked by the OTDR and the data for each event must be retrievable. Acceptance testing should involve the following tests: Link distance, Event Loss and Event Return Loss. IBM will provide an OTDR trace for each fiber link in each direction. Test documentation has to be stored on a floppy disk and printed with all test results labeled. 3. For system acceptance from the OTDR data, individual splice losses will not exceed 0.15 dB. Individual splice loss will be determined by the average of the indicated loss from each direction of an individual splice. 4. The maximum optical attenuation per each mated connector pair shall not exceed 0.75 dB 5. Testing with the Link Loss Test Set will be done to measure the actual end to end loss of the fiber link. The Link Loss Test will be documented with the source transmitting down each direction of the fiber link at both 1310 and 1550 run. The results of the Link Loss Test for each set of fiber links will be provided in a table on paper and as a spreadsheet file. Fiber Link Testing criteria: a) Link loss for 1310 run not to exceed 0.35 dB per kilometer, plus 0.15 dB per splice, plus 0.75 dB per termination. b) Link loss for 1550 nm not to exceed 0.30 dB per kilometer, plus 0.15 dB per splice, plus 0.75 dB per termination. c) No individual splice loss will exceed 0.15 dB. d) No anomalous loss or event will exceed 0.1 dB. 1. All testing is to be done through connectors. 2. Any fiber that fails testing must have appropriate corrective action taken to rectify the situation. 3. The single mode connectors return loss shall be not less than 55 dB. .' C.6.2 System Acceptance 1. All of the fiber optic cabling has been installed and testing has been successfully completed. 2. The construction area above ground will be inspected to see that the following: · Restoration has been accomplished. · Permanent markers have been installed immediately beside the cables. · Road bores, if used, are properly completed and will not collapse a portion of the road. · Debris and trash have been removed from the site. · Other instructions specific to the installation have been completed to the project manager's specifications.
