Loss Performance of Standard Single Mode Fibre Cables In the Wavelength Region 1200-1750nm

摘要

In this paper, we provide measurement results of installed standard single mode fibre cables, which reveal the wavelength dependence of the fibre loss from 1200 nm to 1750 nm. Old cables as well as new cables have been investigated. Values of measured fibre cable loss at different wavelengths are given, and characteristics of the observed loss behaviour are outlined. We also reveal the wavelength dependence of additional losses due to temperature, tension and crush for cable samples under test. The field measurements and the cable tests indicate that the average loss in recently installed cables should be less than approximately 0.40 dB/km in the entire wavelength range 1260 nm - 1675 nm.
