What is Indoor Optical Cable
Indoor optical cables are optical cables laid in buildings and are mainly used for communication equipment, computers, switches and end-user devices in buildings to transmit information.
Introduction
Indoor optical cables are classified according to the use environment of optical cables, as opposed to outdoor optical cables.
Indoor optical cable is a cable formed by optical fiber (optical transmission carrier) through a certain process. It is mainly composed of optical fiber (glass filament as thin as hair), plastic protective sleeve and plastic outer skin. There is no metal such as gold, silver, copper and aluminum in the optical cable, and generally has no recycling value.
Indoor optical cable is a kind of communication line in which a certain number of optical fibers form a cable core according to a certain method, which is covered with a sheath, and some are also covered with an outer sheath to realize optical signal transmission.
Indoor optical cables are mainly used for wiring in buildings and connections between network devices. No metal. Indoor optical cables generally have a short distance and can use multi-mode. The same multi-mode bandwidth can be used for gigabit and 10-gigabit optical cables. Generally, non-metallic reinforced cores are used, and aramid fibers are used. The communication unit will consider bending-resistant G657 optical fibers. There are butterfly cable (also known as leather cable) and so on.

Optical cable classification
Indoor optical cables are classified according to the use environment of optical cables, as opposed to outdoor optical cables.
Indoor optical cable classification, because the indoor optical cable is limited by the building environment, laying conditions, etc., the structural design of the indoor optical cable tends to be complicated, the materials used for optical fibers and optical cables are diversified, and the mechanical properties and optical properties of optical cables have their own emphasis.
a. Divided by usage environment and location
It can be divided into three types: indoor trunk cable, indoor distribution cable and indoor relay cable.
The indoor trunk optical cable mainly provides the channel between the inside and outside of the building; and the indoor distribution optical cable and the indoor relay optical cable are used to transmit information to specific locations respectively.
b. According to the number of fiber cores
Can be divided into single-core, dual-core and multi-core three.
Indoor optical cables usually contain 1-36 cores, and there are also large-core optical cables larger than 36 cores, and even ultra-large core-count high-density optical cables.
The optical fibers in the cable include single-mode optical fibers, multi-mode optical fibers, dispersion-shifted optical fibers and polarized optical fibers, and plastic optical fibers may also be used.
c. According to the shape of the fiber
Polarized (B), circular (E) and other indoor optical cables (different according to radiation environment requirements)
d. According to the position of the optical fiber in the cable or the structure of the optical cable
There are central bundle type, twisted type, skeleton type and stacked belt type indoor optical cable for overcoming difficulties.
e. According to the sheath material
There are flame retardant and non-extended combustion fiber optic cables.
Features
Indoor optical cable has low tensile strength, good bending resistance and poor protective layer, but it is also lighter and more economical.
As the name suggests, the indoor optical cable is generally suitable for indoor optical cable. It is generally divided into two types: indoor tight sleeve and branch. Because it is used indoors, it does not need a waterproof structure, so it has good flexibility and high bending performance. The transmission speed is fast, the signal is clear and stable, the interference is good, and the transmission flow is large.
Fiber optic cable application
Indoor optical cables are mainly used for wiring in buildings and connections between network devices.
