Home-entrance connected optical cable

Abstract

The invention discloses a home-entrance connected optical cable. The optical cable comprises a glass optical fiber located in the center, a cladding wrapping an external portion of the glass optical fiber, a soft protection layer wrapping an external portion of the cladding and a hard protection layer wrapping an external portion of the soft protection layer. An external portion of the hard protection layer possesses a heat preservation and antifreeze filling layer. An external portion of the heat preservation and antifreeze filling layer possesses an outer rubber sheath layer. A plurality of tensile wires are arranged in the outer rubber sheath layer along a peripheral direction. Each tensile wire comprises a center nylon wire and a plurality of thin steel wires wrapping an external portion of the center nylon wire. Through the above mode, the structure is simple and reasonable; the optical cable possesses heat preservation and antifreeze performance and is suitable for being used in a cold rural region.

Description

technical field [0001] The invention relates to the technical field of optical cables, in particular to an optical cable for connecting households. Background technique [0002] Optical fiber network communication is entering people's daily life. It has the advantage of fast transmission rate, and the old cable transmission has been gradually eliminated. The buildings in the city are all equipped with optical cables in each unit and room during the construction process. After people move in, they only need to apply for a simple opening to use optical fiber communication. [0003] At present, optical fiber communication projects have also begun to spread to the vast rural areas. The rural areas are all single-family small courtyards. To pull optical fiber, you need to connect the incoming optical fiber from the optical fiber pile on the roadside, and then pull the incoming optical fiber to the home. Some such home-entry optical fibers have poor frost resistance, and the opti...

[0003] At present, optical fiber communication projects have also begun to spread to the vast rural areas. The rural areas are all single-family small courtyards. To pull optical fiber, you need to connect the incoming optical fiber from the optical fiber pile on the roadside, and then pull the incoming optical fiber to the home. Some household optical fibers have poor frost resistance, and the optical fibers tend to become brittle at low temperatures, which is prone to breakage. The existing household optical fibers are not suitable for use in cold rural areas.
