fiber optic cable to ensure the service life of more than 20 years
in the long-distance optical cable communication system, optical fiber transmission characteristics should be stable for a long time, especially long-distance mains directly buried cable and submarine cable system, long life put forward higher requirements for fiber optic cable. the general land cable service life and hope to have more than 20 years of safe-use period, for submarine cable, insist on the service life is increased to more than 25 years, the average time between failures for 10 years. therefore, how to extend the service life of the cable, how to properly use fiber optic cable, is an important technical issues people care about, from the aspects of the structure of the cable under the talk about how to prolong the service life of the cable.
of the three major factors affecting the service life of optical fiber in optical fiber cable
optical fiber is
