Did you know that indoor optical cables are classified according to the environment in which the optical cables are used

Indoor optical cables are classified according to the environment in which the optical cables are used, as opposed to outdoor optical cables.

The classification of indoor optical cables. Due to the limitations of the building environment and laying conditions, the indoor optical cables have become more complicated in structural design, the materials used for optical fibers and optical cables are diversified, and the mechanical and optical properties of optical cables have different emphasis.

a. divided according to the use environment and location
It can be divided into three types: indoor backbone optical cable, indoor distribution optical cable and indoor relay optical cable.
Indoor backbone optical cables mainly provide channels between inside and outside of buildings; indoor distribution optical cables and indoor relay optical cables are used to transmit information to specific locations, respectively.

b. Divided by the number of optical fiber cores
It can be divided into single core, double core and multi core.
Indoor optical cables usually contain 1-36 cores, and there are also large-core optical cables larger than 36 cores, and even high-density optical cables with extra large cores. The optical fibers in the cable include single-mode optical fibers, multi-mode optical fibers, dispersion-shifted optical fibers and polarized optical fibers. Plastic optical fibers may also be used.

c. According to the shape of the optical fiber, there are partial (B), round (E) and other shapes of indoor optical cables (different according to the requirements of the radiation environment)

d. According to the position of the optical fiber in the cable or the structure of the optical cable, there are a central beam tube type, a twisted type, a skeleton type and a stacked tape type indoor optical cable for crossing the storm.

e. According to the sheath material, there are flame-retardant and non-flame-retardant indoor optical cables.
Indoor optical cables have low tensile strength and poor protective layer, but they are also lighter and more economical. Indoor optical cables are mainly suitable for wiring in buildings and connections between network equipment. No metal.
The indoor optical cable is generally not long, you can use multimode, the same multimode bandwidth can use Gigabit and 10 Gigabit optical cables, generally non-metallic reinforced core, using aramid, etc., the communication unit will consider bending G657 type optical fiber There are butterfly-shaped optical cable (also known as leather cable) and so on. As the name implies, indoor optical cables are generally suitable for indoor optical cables. He is generally divided into indoor tight sleeves and branches. Because it is used indoors, he does not need a waterproof structure, so the softness is better and the bending performance is high. The transmission speed is fast, the signal is clear and stable, the interference is good, and the transmission flow is large.
