Abstract
The utility model relates to a frame type optical fiber band and loose double-pipe mixed optical cable used for light transmission line of optical telecommunications network, comprising a frame, a water-blocking member and an outer sheath. An optical fibre band groove and an optical fibre band are arranged around the frame. The difference is that a casing groove is also arranged in the circular direction of the frame and the casing groove is coated with a loose pipe sheathed with an optical fibre. The utility model has the advantages that both the optical fibre band and a separable optical fibre are arranged in the optical cable by simultaneously arranging the optical fibre band and the loose pipe in the frame type optical cable. The mixed optical cable composed by the method is more suitable for matching in construction with originally coated optical cables and optical fibre distributing frames (ODF frame). Users can continuously connect by the band type optical fibre in the optical cable or the separable optical fibre according to requirement when users meet branching. The utility model is convenient for the optical cable construction under complicated states. In addition the band type optical fibre in the inner frame can also be used for long-distance transmission. The loose pipe in SZ strand in the outer frame can be used in access networks, and the optical cable does not need to be cut when users meeting branching so that the utility model is convenient.
Description
Technical field
The utility model relates to a kind of skeleton and loose sleeve pipe layer-twisted type mixed type optical cable that is used for the fiber optic communication network optical transmission line.
Background technology
Existing slotted core fiber ribbon cable is made of skeleton, the fibre ribbon, waterstop, moisture barrier and the oversheath that are installed in the skeleton grooves, and the big characteristics of fibre ribbon amount that intensity is good owing to having, structure is provided with rationally, can place are widely used.Yet, existing slotted core fiber ribbon cable only is placed with fibre ribbon and does not have and separate fine (simple optical fiber), joins with former laying optical cable and fibre distribution frame (ODF frame) when it in practice of construction, need be when difference when separating fibre and continue, can't realize easily, bring trouble to construction.
Summary of the invention
Technical problem to be solved in the utility model be to overcome the deficiency that prior art exists and provide a kind of when construction, be convenient to fibre ribbon with separate the skeleton and loose sleeve pipe layer-twisted type mixed type optical cable that fibre continues.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: include skeleton 1, water-blocking component and oversheath 9, being circumferentially with fine trough of belt and installing fibre ribbon 3 of skeleton, its difference is to be laid with loose sleeve pipe 4 in the periphery of skeleton cable core, is set with optical fiber 5 in the loose sleeve pipe.
Press such scheme, described skeleton middle part is installed on central reinforce member 7; Described water-blocking component is a waterstop 2, is coated on the periphery of skeleton cable core periphery and the loose sleeve pipe of layer strand respectively; Can coat moisture barrier outside layer twists the waterstop of loose sleeve pipe periphery, described moisture barrier is moistureproof metal tape 6; Described oversheath 9 is common or fire-retardant PE oversheath.
The beneficial effects of the utility model are by fibre ribbon and loose sleeve pipe are set in optical cable simultaneously, make that existing fibre ribbon has separation optical fiber again in the optical cable, constitute the mixed type optical cable thus, more be applicable in construction and the cooperating of former laying optical cable and fibre distribution frame (ODF frame), the user can continue with fibre ribbon in the cable or separation fibre when difference as required, bring convenience to the optical cable construction under the complex state, also can reduce the cost of fiber cable laying.Also the fibre ribbon in the inner framework can be used for long-distance transmission in addition, separate optical fiber in the stranded loose sleeve pipe of outer SZ and be used for Access Network, need not to cut off optical cable during difference, very convenient.The utility model also has the characteristics that intensity is good, structure is provided with rationally, consumptive material is few and cost of manufacture is low.
Description of drawings
Fig. 1 is the radial section structural drawing of an embodiment of the utility model.
Fig. 2 is the radial section structural drawing of another embodiment of the utility model.
Embodiment
An embodiment of the present utility model as shown in Figure 1, include the skeleton 1 that extends to two of a uniform cross section, make by high density polyethylene, the skeleton middle part is installed on central reinforce member 7, central reinforce member is the metal center reinforcement, circumferentially offer fine trough of belt at skeleton, fine trough of belt shape or SZ shape in the shape of a spiral extends forward, in fine trough of belt, lay the fibre ribbon 3 that is formed by stacking, constitute the skeleton cable core thus, fibre ribbon is lined up flat by optical fiber communication and is formed with UV curing acrylic resin-coating or bonding, can be 4 cores, 6 cores or 8 core fibre bands have waterstop 2 in the wrapping of the periphery of skeleton cable core; The stranded one deck pine of the waterstop periphery that is coated at skeleton cable core sleeve pipe, be set with optical fiber 5 in the pine sleeve pipe 4, be extruded into sleeve pipe with plastics in outside of fiber and form, simultaneously fill greasy for preventing water between loose sleeve pipe and optical fiber, loose sleeve pipe shape or SZ shape in the shape of a spiral extends stranded forward; Loose sleeve pipe periphery wrapping in layer strand has waterstop 2, the moistureproof metal tape 6 of vertical again bag outside waterstop, and moistureproof metal tape can be moistureproof aluminium strip, outermost layer coats oversheath 9, oversheath can be the PE oversheath, can install in the oversheath and tear rope 8, constitutes a kind of mixed type optical cable of half dry type structure.
Second embodiment of the utility model as shown in Figure 2, the difference of it and a last embodiment is to set up the moistureproof metal tape of one deck outside the waterstop 2 that the skeleton cable core is wrapped up, coat inner sheath 10 outside moistureproof metal tape again, inner sheath can be the PE inner sheath.All the other structures are identical with a last embodiment.
The fine trough of belt of the utility model skeleton and loose sleeve pipe number should be earlier according to contained fibre ribbon in the cable with separate how many designs of optical fiber, for example, this optical cable can form and comprise 96 core fibre bands and add 144 cores and separate the optical fiber structure of totally 240 cores.Each groove size of skeleton is by the corresponding requirements design, and its diameter then determines according to the requirement of loose casing layer strand.
During the utility model stranding fibre ribbon routinely technology put into fine trough of belt, wrapped waterstop, according to circumstances wrap up moisture barrier and coat inner sheath, then with this cable core be the center strengthen the unit with loose sleeve pipe routinely technology carry out stranded, to guarantee that by structural design and Tension Control optical fiber all obtains suitable surplus length in fibre ribbon and the sleeve pipe, carry out the processing and the making of outer waterstop, moisture barrier and oversheath then successively.
