Abstract
The utility model discloses a flexible steel tube armour optical cable of 8 styles of calligraphy in two cores, including two single core optical fiber units, two single core optical fiber unit parallel arrangement, the optical cable cross -section is 8 styles of calligraphy, block water area (2), flexible nonrust steel pipe (3), aramid fiber pipe (4), silica gel sheath (5) and the aramid fiber yarn enhancement layer (6) of single core optical fiber unit are by interior and cladding in the outside of tight tube fiber (1) in proper order outward, and the aramid fiber yarn enhancement layer (6) of two single core optical fiber units is connected as an organic wholely. The utility model discloses a two single core tight tube fiber, make that the optical cable wholly has that the external diameter is little, light in weight, easily peel off, bending property is good, arrange characteristics such as compact easy wiring. Adopt inorganic high temperature resistant silica gel oversheath, the silica gel sheath is high temperature resistant 200-250 DEG C, promoted the high temperature resistance ability of optical cable. The silica gel sheath is equipped with aramid fiber yarn enhancement layer outward, has improved the mechanical properties such as tensile, resistance to compression of optical cable. Tight tube fiber's the outside is wrapped up by the area that blocks water, and the block -water performance of optical cable is excellent.
Description
Technical field
The utility model relates to a kind of optoelectronic composite cable, particularly relates to a kind of twin-core 8 font flexible steel pipe armored optical cable.
Background technology
Along with the arrival of information age, the conveying capacity of information is explosive growth, as the effective means of Large Copacity, long range propagation, optical fiber cable obtains extensive and a large amount of application, the application of optical cable also gradually by long distance line to Metropolitan Area Network (MAN), Access Network future development.
Existing cable configuration is comparatively simple, be made up of single core tight tube fiber and the restrictive coating being coated on single core tight tube fiber surface, there is following defect: the bad mechanical properties such as tension, resistance to compression, bend resistance, in use easily cause the broken skin of optical fiber even to rupture, cause the transmission of light signal lose or interrupt.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of twin-core 8 font flexible steel pipe armored optical cable, has the mechanical propertys such as good tension, resistance to compression, bend resistance, and have external diameter little, arrange the features such as compact easy wiring.
The purpose of this utility model is achieved through the following technical solutions: twin-core 8 font flexible steel pipe armored optical cable, and comprise two single-core fiber unit, two single-core fiber unit are arranged in parallel, and cable cross-section is 8 fonts; Described single-core fiber unit comprises tight tube fiber, waterstop, flexible stainless-steel tube, aramid fiber pipe, silica gel sheath and aramid yarn enhancement Layer, waterstop, flexible stainless-steel tube, aramid fiber pipe, silica gel sheath and aramid yarn enhancement Layer are coated on the outside of tight tube fiber from inside to outside successively, and the aramid yarn enhancement Layer of two single-core fiber unit connects as one.
Described flexible stainless-steel tube is double plastic-coated stainless-steel tube.
Described silica gel sheath is inorganic high-temperature resistant silica gel sheath.
The beneficial effects of the utility model are:
1) adopt two single core tight tube fibers, make optical cable entirety have the features such as little, lightweight, the easy stripping of external diameter, good bending property, the compact easy wiring of arrangement.
