Definition of optical cable

Optical fiber cable (optical fiber cable) is manufactured to meet optical, mechanical or environmental performance specifications. It is a communication that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups Cable assembly.

Types of optical cables

1. Bend insensitive optical cable

Ordinary optical cables have weak resistance to bending, so protective facilities such as pipes are used to lay the optical cables when wiring indoors. In addition, the indoor space is small and the wiring environment is more complicated, and the transmission quality often deteriorates due to the bending of the optical cables. At the same time, wiring workers also need to be careful when laying optical cables, which will increase labor costs. In order to solve these problems, the bending-insensitive optical cable is produced. It conforms to the ITU-T G.657 standard and can generally support a bending radius of 7.5mm. With its help, many difficulties in indoor installation of optical cables will be solved.

2. Indoor and outdoor dual-purpose optical cable

Most of the indoor and outdoor dual-purpose fiber optic cable connection terminals are located in residential areas, streets, buildings or computer rooms. These places need to consider the flame retardant performance and waterproof performance of the optical cable, so indoor and outdoor dual-purpose optical cable products will use fire-resistant sheath materials and use water-swellable materials to achieve flame retardant and waterproof performance

3. Pipe fiber optic cable

Duct optical cables are generally laid in urban areas, and the environment is relatively good, so there are no special requirements for the optical cable sheath, and no armoring is required. This kind of optical cable generally adopts non-metallic sleeve, mostly 12-core design, usually loose tube, small sheath and other structures.
