Indoor optical cable is an optical cable laid in a building. It is mainly used to connect communication equipment in the building in order to transmit information. It is mainly divided into backbone optical cable (vertical optical cable), horizontal optical cable (distribution optical cable) and work There are several types of regional optical cables (flexible optical cables, jumpers, etc.). Because indoor optical cables are restricted by the construction environment, laying conditions and user choices, the structural design of indoor optical cables tends to become more complicated and special. The selected materials for optical fibers and optical cables Diversification, specialization of optical cable testing methods, etc.
Inner cable characteristics
The typical structure of indoor optical cable has single core, double core and multi core.
Optical cables usually contain 1 to 36 core optical fibers, and there are also high-density optical cables with a large number of cores and even a large number of cores greater than 36 cores. For example, 72 cores and 144 cores are also used more, but most of them are below 12 cores; indoor optical cables Most of the performance requirements are the same as outdoor optical cables, but due to the influence of various factors such as the use environment, laying conditions, optical cable materials and user choices, indoor optical cables have their unique characteristics and requirements.
