Characteristics of outdoor fiber optic cable
- Sep 07, 2018 -

Water-resistant Belt longitudinal package prevents longitudinal seepage of optical cable.

Two parallel wire to ensure the tensile strength of the cable The tensile strength of the outdoor cable is larger, the protective layer is thicker, and usually armored (that is, metal skin wrapped).

Outdoor optical cables are mainly used for interconnection between buildings and remote networks. Generally speaking, outdoor optical cable is only filler, strengthen components, sheath, etc. choose different materials. such as: Outdoor cable directly buried, it is advisable to choose armoured cable.

When overhead, a black plastic outer sheath with two or more reinforcing ribs can be selected.

Outdoor optical cable because its use environment is outside, so it must have waterproof function, the general use of the outer sheath is made of PE material, and then its internal structure is generally divided into central tubular structure and layer twisted structure.

From the naked eye, the indoor outer sheath is generally yellow or orange PVC material, outdoor is a black PE sheath, from the model to distinguish the outside generally have Gy words.

Outdoor Optical Cable: Outer packing thickness, with pressure, corrosion resistance, tensile and other mechanical properties, environmental characteristics.

Indoor optical Cable: Mainly used in indoor, the main features to have easy to bend characteristics, can be used in the corner and other narrow places, followed by fire-retardant, anti-tensile, soft and other external characteristics. Outdoor optical cable is a kind of communication line to complete optical signal transmission.

By a certain number of optical fiber in accordance with a certain way to form the core of the cable, outsourcing has a sheath, and some also cover the outer layer. The outdoor fiber optic cable is mainly composed of optical fiber (thin hair glass wire) and plastic maintenance casing and plastic sheath, there is no metal such as gold, silver, copper and aluminum in the cable.
