A uni-directional test will be conducted on all pigtail splices with no greater than a. 8 dB after 5 repeated attempts results in the replacement and re-splicing of that pigtail. To be able to judge whether a fiber optic cable plant is good, one does a insertion loss test with a light source and power meter and compares that to an estimate of what is a reasonable loss for that cable plant. Factors causing fiber loss are various, such as intrinsic material absorption, bending, connector loss, etc. This is inherent in all fiber types and happens even under ideal conditions. When the single-mode fiber pigtail is less than 50M and the multi-mode fiber pigtail is less than 10M, the loss of the pigtail itself can be ignored, and the measured data at this. Built to meet the rigorous demands of modern telecommunication and data center networks, each Unisol fiber optic pigtail offers excellent performance in terms of insertion loss, return loss, and long-term mechanical reliability.
