Full-dry high count armour indoor and outdoor optical cable

Abstract

The invention relates to a full-dry high count armour indoor and outdoor optical cable comprising a reinforcement, a plurality of unit cables, an inner sheath, a metal armour cover and an outer sheath, wherein the reinforcement is arranged in the center, a plurality of unit cables are arranged on the periphery of the central reinforcement in a twisting mode, the inner sheath is covered on the periphery of unit cables, the metal armour cover is sheathed on the periphery of the inner sheath, the outer sheath is covered on the periphery of the metal armour cover, and each unit cable comprises a loose tube and a plurality of tight-coated fibers arranged in the loose tube. Because the optical cable of the invention is provided with the metal armour cover, the steel cable has certain side pressure proof performance, moist resistance performance and rat damage resistance and can be applied indoors and outdoors. The optical cable of the invention has small weight, does not contain liquid such as ointment and the like and is the full-dry optical cable, so that the optical cable is convenient to lay and continue.

Description

technical field [0001] The invention relates to a communication optical cable. Background technique [0002] In the application of Fiber To The Home (FTTH, Fiber To The Home), the fiber optic cables between buildings mainly adopt such as figure 1 and figure 2 shown for use with fiber optic cables where, figure 1 The shown optical cable has a strengthening member 10 in its center, and a plurality of unit cables 20 are twisted and arranged on the outer periphery of the strengthening member 10, and a sheath 30 is coated on the outer periphery of the unit cables 20, and a plurality of optical fibers are arranged in each unit cable 20 201. This kind of optical cable is mainly used as an optical connection between buildings. When it is connected to the room, it needs to use figure 2 In the optical cable shown, the center of the optical cable is still a strength member 100, and two layers of tight-buffered optical fibers 200 are twisted and arranged on the periphery of the str...

[0002] In the application of Fiber To The Home (FTTH, Fiber To The Home), the fiber optic cables between buildings mainly adopt such as figure 1 and figure 2 shown for use with fiber optic cables where, figure 1 The shown optical cable has a strengthening member 10 in its center, and a plurality of unit cables 20 are twisted and arranged on the outer periphery of the strengthening member 10, and a sheath 30 is coated on the outer periphery of the unit cables 20, and a plurality of optical fibers are arranged in each unit cable 20 201. This kind of optical cable is mainly used as an optical connection between buildings. When it is connected to the room, it needs to use figure 2 In the optical cable shown, the center of the optical cable is still a strength member 100, and two layers of tight-buffered optical fibers 200 are twisted and arranged on the periphery of the strength member 100, and finally covered by an outer sheath 300, that is to say, in FTTH applications, it is necessary to Only two types of optical cables can complete the wiring, and the construction is troublesome, and for figure 2 When the optical cable shown is used for pipeline laying, due to its soft material, it is not suitable to be laid in places with corners. At the same time, its ability to resist lateral pressure is poor, and it will affect the optical fiber when it is trampled on the road. transmission performance
