Optical fiber is promoted to be used as the media of information of distance.Along with optic fibre manufacture process field and manufacture apparatus field further
Optimizing or development, existing fiber price reduces further, and optical fiber improves the most rapidly at the total proportion of signal communication cable.Light
Cable is that a number of optical fiber forms the cable heart according to certain way, is surrounded by outward sheath, and the also cladding outer jacket having, in order to realize light
A kind of communication line of signal transmission.Along with informationalized development, the conveying capacity of information increases rapidly, and optical fiber cable has obtained greatly
The application of amount.The cable configuration used at present is relatively simple, and this optical cable is by single tight tube fiber and is coated on single and tightly overlaps
The restrictive coating of optical fiber surface is constituted, and the production technology of this optical fiber is relatively simple, the bad mechanical property of optical fiber, in construction or use
During be easily caused the bending of optical fiber or fracture, ultimately result in the Transmission of optical signal, had a strong impact on fiber-optic transfer special
The long-time stability of property.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, there is the high mechanical properties optical cable of high tensile anti-pressure ability.
The present invention is achieved through the following technical solutions: a kind of high mechanical properties optical cable, including oversheath, is arranged on oversheath
In support member, the inner sheath being arranged between oversheath and support member, several fiber boots of being arranged in inner sheath

Described support member include several separate limit, several separate limits be integrated into hub-and-spoke configuration, inner sheath
It is arranged between separation limit and oversheath.
Described oversheath uses PE to make.
Cable cream it is filled with between described inner sheath and fiber optic protection sleeve pipe.
Described armor bonds together with support member.
Described armor is bonded together by epoxy resin adhesive with support member.
Waterproof gauze it is provided with between described inner sheath and armor.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) present invention is by arranging support member in oversheath, it is possible to will be divided into multiple region in sheath, in order to install many groups
Optical cable, and support member can play the effect of isolation, prevents inner sheath to tangle, and makes the easy branch of optical cable, by using
Support member can also play the effect of support, improves the resistance to compression of the present invention, bending resistance, improves the mechanical strength of optical cable, logical
Cross and armor is set, by increasing capacitance it is possible to increase the mechanical strength of the present invention, desirably prevent inner sheath deformation and oppress optical fiber, thus play
The effect of protection optical fiber, and also the anti-pressure ability of the present invention can be improved；
(2) by the present invention in that separate limit is integrated into hub-and-spoke configuration, be conducive to making the space decile in oversheath so that optical cable
Can uniform force, be conducive to making power disperse, thus improve the lateral pressure resistant ability of optical cable；
(3) by the present invention in that armor bonds together with support member, it is possible to increase armor and the bonding strength of support member,
Thus be conducive to improving the mechanical strength of the present invention, and increase tension, lateral compressive strength；
