For mid -span termination cable entry, cut only those individual fiber bundle/strands needed (ring cut) for connection to the devices. For those fibers designated for trunk line communications, do not cut the fibers or install cables that require splices at lengths less than 2,500 feet.

Provide 2 paper copies and 1 electronic copy of the results immediately to the RE for review and approval. Clearly identify each fiber on the report. Ensure that the maximum splice loss does not exceed 0.05 decibels. If the 0.05 decibel value cannot be reached in 3 attempts, the RE may employ a third party vendor to redo the work. The Department will recover the cost as specified in 107.16. Provide the RE with certification from the equipment manufacturer that the splice machine was calibrated within 3 months of its use on the Contract. Recalibrate the splice machine at 6 month intervals from the initial calibration by the manufacturer.

Ensure that the maximum decibel loss for any single event is not greater than 0.3 decibels at 1,310 nanometers; however, ensure that the OTDR machine threshold is set to record events greater than or equal in absolute value to 0.05 decibels along the positive and negative axes. Events revealed by the OTDR machine bi-directional trace average to exceed 0.3 decibels are cause for the rejection of the cable. If directed, remove and replace the cable. Ensure that the net result of the bi -directional trace average at 1,310 nanometers across a splice event is not greater than 0.15 decibels. Redo splices revealed by the OTDR machine to be great er than 0.15 decibels up to 2 additional times in order to achieve 0.15 decibels or less. If the 0.15 decibels value cannot be reached in 3 attempts, the RE may em ploy a third party vendor to re do the work. The Department will recover the cost as specified in 107.16. Ensure that reflectance at each connector is better than −55 decibels. Ensure the fiber loss across each fiber segment is not greater than 0.4 decibels per kilometer when tested at 1,310 nanometers. Also test, and include in the report, the dark fiber segments that are not being utilized by the signal transmission equipment. Provide connectors as necessary to test unterminated fibers. Provide 2 paper copies and 1 electronic copy of the results immediately to the RE for review and approval. Clearly identify each fiber on the report.
