Abstract
The utility model relates to a self-supporting bow-type optical cable in the field of photoelectric communication. The self-supporting bow-type optical cable comprises a bow-type optical cable and a wire suspending piece, and is characterized in that an external protecting layer wrapping and connecting the bow-type optical cable and the wire suspending piece; cable separation yarns are arranged between the external protecting layer and the bow-type optical cable; the bow-type optical cable comprises a constant-section bow-type sheath; and an optical fiber unit is wrapped in the middle of the bow-type sheath. According to the utility model, the bow-type optical cable is well protected outdoors, and the weatherability and the mechanical properties of the optical cable are improved; the cable separation yarns arranged between the external protecting layer and the bow-type sheath facilitate stripping off the external protecting layer and separating the bow-type optical cable, thereby bringing convenience for independent home-entry of the bow-type optical cable, and facilitating maintaining the shape and the dimensional precision of the bow-type optical cable and quickly interlinking a cold joint and the field, and therefore, the use is facilitated; and as parallel reinforcers are arranged in the external protecting layer and the optical cable, the bow-type optical cable has improved mechanical properties and uniform stress.
Description
Technical field
The utility model relates to a kind of self-bearing type butterfly optical cable that is used for the photoelectric communication field.
Background technology
Along with the development of photoelectric communication to FTTB (Fiber To The Building), FTTO (Fiber-To-The-Office), FTTH directions such as (fiber-to-the-home front yards), butterfly optical cable is used in Access Network in a large number.Be to simplify construction maintenance, a kind of self-bearing type butterfly optical cable that can use at indoor and outdoors simultaneously is widely used: outdoor section its can be used as that self-support cable is built on stilts to be used; Before optical cable is registered one's residence, the messenger wire element cut off and be fixed on the dedicated fixed device, the residue optical cable removes and becomes butterfly optical cable behind the messenger wire element and introduce indoorly, cooperates fast connecting joint or optical fiber cold connector to use.
Butterfly optical cable is as the optical cable of registering one's residence, and its fire resistance is had relatively high expectations, and the butterfly sheath mostly is to be processed by halogen-free low-smoke flame retardant material, though have a fire resistance preferably indoor, the adding of flame-retardant additive also causes the deterioration of performances such as sheath physical mechanical.Therefore butterfly optical cable partly is prone to the impaired situation of sheath cracking when the self-bearing type butterfly optical cable is hung outdoor use for a long time, thereby influences the transmission performance and the serviceable life of optical cable.
Summary of the invention
The utility model technical matters to be solved is the deficiency that exists to above-mentioned prior art and proposes a kind of modified self-bearing type butterfly optical cable; It can not only improve the weather resistance of optical cable; Strengthen optical cable transmission performance reliability and serviceable life, and easy to use.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is:
Include butterfly optical cable and messenger wire spare, it is characterized in that being provided with the outer jacket that coats butterfly optical cable and messenger wire spare and both are linked, between outer jacket and butterfly optical cable, be provided with out the cable yarn.
Press such scheme, described butterfly optical cable includes prismatic butterfly sheath, in the middle of the butterfly sheath, coats fiber unit.
Press such scheme, described butterfly sheath is processed by halogen-free low-smoke flame retardant material or other fire proofing.
Press such scheme, the upper and lower sides in said butterfly sheath inner fiber unit is provided with parallel reinforcement respectively.
Press such scheme, the described cable yarn of opening is 2, is separately positioned on the outer both sides of butterfly sheath.
Press such scheme, described fiber unit is for separating optical fiber, fibre ribbon, tight tube fiber or fibre bundle.
Press such scheme, described parallel reinforcement is sub-thread or strands of metal wire, or aramid yarn, or non-metallic rods.
Press such scheme, described outer jacket is processed by tygon or the good macromolecular material of other weather resistance.
The beneficial effect of the utility model is: 1, outer jacket coating butterfly optical cable and messenger wire spare are set and both are linked into one, butterfly optical cable is well protected out of doors, improved the weather resistance and the mechanical property of optical cable; 2, between oversheath and butterfly optical cable, be provided with and open the cable yarn and can be convenient to opening separating of stripping and butterfly optical cable of outer jacket; Being convenient to butterfly optical cable registers one's residence separately; Be beneficial to the maintenance of butterfly optical cable shape and size precision, be convenient to do cold junction and on-the-spot fast link, bring convenience to use; 3, because the setting of parallel reinforcement in outer jacket and the cable improves the butterfly optical cable mechanical property, stressed evenly.
Description of drawings
Fig. 1 is the radial structure sectional view of first embodiment of the utility model.
Fig. 2 is the radial structure sectional view of another embodiment of the utility model.
Embodiment
Further specify the embodiment of the utility model below in conjunction with accompanying drawing.
First embodiment is as shown in Figure 1, is a single core self-supporting butterfly optical cable, includes butterfly optical cable; Described butterfly optical cable includes prismatic butterfly sheath 3, and the butterfly sheath is processed by LSZH, PVC or other halogen-free low-smoke flame retardant material, in the middle of the butterfly sheath, coats fiber unit 5; Described fiber unit is that single core separates optical fiber, and the upper and lower sides of butterfly sheath inner fiber unit is provided with parallel reinforcement 6 respectively, and described parallel reinforcement is an elementary wires; Messenger wire spare 1 is set above outside the butterfly sheath, and messenger wire spare is steel wire or fiber rod, messenger wire spare and butterfly sheath parallel interval; At the butterfly sheath with messenger wire spare is coated with outer jacket 2 and two outer jackets are linked into one; Outer jacket is processed by tygon, between outer jacket and butterfly optical cable, is respectively arranged with out cable yarn 4 in the groove of butterfly sheath both sides, opens the cable yarn and vertically lays along groove; Opening the cable yarn can be aramid yarn or other silvalin so that outer jacket open stripping.
Second embodiment such as Fig. 2, the difference of itself and first embodiment is that optical communication element is the four-core fibre ribbon, other structure is identical with first embodiment.
