Development of optical drop-cable suitable for wiring through the conduit run (sewer system, buildings, etc.)

摘要

As demand for high-speed Internet increases, the use of FTTH (Fiber To The Home), capable of high-speed and large-capacity transmission is rapidly diffusing. As one of the means to realize FTTH, techniques for using sewage systems have been developed. We have developed thin, light and flexible loose tube type optical drop cables that are suitable for wiring in conduits and most appropriate for FTTH using sewage systems. The loose tube type optical drop cables can be used not only for wiring in conduits, but also for indoor LAN (Local Area Network) wiring when multi-mode fibers are used as housed core wires and flame-retardant polyethylene sheaths are used for cable sheathing.
