What is the indoor cable

Indoor cable, indoor fiber optic cable is mainly used for indoor wiring and the indoor variety of communications devices, equipment and instruments, the connection between the meter and the meter.

Fiber to the home is believed to be the future direction of development of the access network. To achieve this goal, people had various efforts, indoor fiber optic cable in the future there will be huge demand.

With the advent of the information age, people's increasing demand for information. China's eight vertical and eight horizontal layers of high-speed fiber optic networks and broadband access networks have been built, the increasing popularity of computer networks, continue to meet the people's increasing demand for communication bandwidth. With fiber to the client continue to extend the application of more and more indoor fiber optic cable, the market demand has heated up. From the vertical cabling system and fiber to the home of the inevitable trend of development and transmission room, all-optical switching network demands, the demand for indoor fiber optic cable the same cable as telephone wiring, cable lines must demand no less. In particular, fiber to the user, fiber to the desktop program gradually, the demand for indoor cable bears great potential for growth, is expected to eventually occupy the national fiber about 50% of total demand.
Indoor wiring cable is mainly used for indoor and indoor variety of communications devices, equipment and instruments, the connection between the meter and the meter. Because it is used indoors, so they are dry most of the use of fiber optic cable structure. In addition to indoor cable should meet the necessary performance of optical transmission, mechanical properties, but also must have a burning feature requests. In order to prevent fires, and now most of the indoor fiber optic cable using LSF or LSZH jacket.

Currently, the assessment of indoor combustion characteristics of the cable is divided into three parts, namely, flame-retardant properties, corrosion resistance and smoke density. Normal use of the indoor cable flammability rating is based on user requirements for different levels of flame retardant to the classification; corrosion by measuring the optical combustion gases and the PH value to determine the conductivity, the combustion gases of PH value should not be less than 4, the conductivity should be less than 100μs/cm; concentration of smoke produced by cable combustion smoke to determine the transmittance of not less than 50%.

Indoor fiber optic cable is currently used mostly single and multi-core cable aramid fiber reinforced soft. Single-core cable is mainly used for indoor optical devices and optical distribution frame optical jumper jumper, multi-core is generally used for building vertical jumper wiring system.
