Abstract

The utility model relates to a photoelectric composite drop cable for FTTH (Fiber To The Home), which comprises a cable core and a jacket layer coating the cable core, wherein the cable core comprises a butterfly-shaped optical cable unit positioned in the center of the cable core and insulating single wires arranged at two sides of the butterfly-shaped optical cable unit; the jacket layer comprises a water-blocking tape wound and coated on the periphery of the cable core, an aluminum tape coated on the periphery of the water-blocking tape and a low-smoke zero halogen outer jacket on the periphery of the aluminum tape by extruding molding. According to the photoelectric composite drop cable, by adopting a mode of combing the butterfly-shaped optical cable unit with the insulating single wires, the power transmission and the optical signal transmission can be carried out simultaneously; and in addition, the whole cable is more flexible, the requirements for different occasions of laying wires indoor and outdoor can be met.

Description

FTTH uses up to reply by cable and closes the introducing cable

Technical field

The utility model relates to a kind of communication cable, relates in particular to the communication cable in the Access Network that is applied in that Fiber to the home (FTTH).

Background technology

In Fiber to the home FTTH uses, butterfly optical cable and more and more used as the optical cable of cable core peripheral hardware sheath by butterfly optical cable, but, above-mentioned cable only possesses the transmission of light signal, there is not the electric power transfer function, in order to satisfy low-carbon environment-friendly, reduce overlapping investment, also can respond simultaneously the energy-saving and cost-reducing requirement that country proposes, four networks one platform is put on the agenda day by day, therefore, can not only carry out the transmission of room light signal to the requirement of cable, also requirement can be carried out signal of telecommunication transmission, and the application just is being based on above-mentioned purpose and the design carried out.

The utility model content

The utility model purpose provides the transmission of a kind of current collection power and optical signal transmission and is suitable for FTTH in one and uses up to reply by cable and close the introducing cable.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of FTTH uses up to reply by cable and closes the introducing cable, it comprises cable core, coat the sheath of described cable core, described cable core comprises the butterfly optical cable unit that is positioned at the center, be arranged on the insulated single wire of both sides, butterfly optical cable unit, described butterfly optical cable unit is by optical fiber, cross section is the low smoke and zero halogen sheath of butterfly, the non-metal reinforcement member that is arranged in the low smoke and zero halogen sheath and is positioned at the optical fiber both sides is formed, described every eradication edge single line is by copper conductor, the insulator that is coated on the copper conductor periphery is formed, and described sheath comprises wrapped waterstop in described cable core periphery, be coated on the aluminium strip of waterstop periphery and extrusion molding low smoke and zero halogen oversheath in the aluminium strip periphery.

Described insulated single wire is arranged on the both sides of butterfly optical cable unit symmetrically.

Also be filled with aramid yarn between the waterstop of described sheath and butterfly optical cable unit and the insulated single wire.

The copper conductor diameter of described insulated single wire is 1 millimeter.

Because technique scheme utilization, the utility model compared with prior art has following advantage: the mode that the utility model communication cable adopts the butterfly optical cable unit to combine with insulated single wire, can carry out electric power transfer and optical signal transmission simultaneously, and whole cable is soft, can satisfy the connect up demand of different occasions of indoor and outdoor.

Description of drawings

Accompanying drawing 1 is the compound introducing cable of a utility model photoelectricity viewgraph of cross-section;

Wherein: 1, cable core; 11, butterfly optical cable unit; 111, optical fiber; 112, low smoke and zero halogen sheath; 113, non-metal reinforcement member; 12, insulated single wire; 121, copper conductor; 122, insulator;

2, sheath; 21, waterstop; 22, aluminium strip; 23, low smoke and zero halogen oversheath; 24, aramid yarn.

Embodiment

Below in conjunction with accompanying drawing, the utility model preferred embodiment is elaborated:

The compound introducing cable of photoelectricity as shown in Figure 1, it mainly is made up of cable core 1, the sheath 2 that is coated on cable core 1 periphery.Wherein, cable core 1 comprises the butterfly optical cable unit 11 that is positioned at the center, the insulated single wire 12 that is arranged on 11 both sides, butterfly optical cable unit.Butterfly optical cable unit 11 by optical fiber 111, cross section be butterfly low smoke and zero halogen sheath 112, be arranged in the low smoke and zero halogen sheath 112 and the non-metal reinforcement member 113 that is positioned at optical fiber 111 both sides is formed.Every eradication edge single line 12 is made up of copper conductor 121, the insulator 122 that is coated on copper conductor 121 peripheries.The diameter of copper conductor 121 is 1 millimeter, and in the present embodiment, two thoroughly do away with the both sides that edge single line 12 is arranged on butterfly optical cable unit 11 symmetrically.

Described sheath 2 is by wrapped waterstop 21 in cable core 1 periphery, the aluminium strip 22 that is coated on waterstop 21 peripheries and the extrusion molding low smoke and zero halogen oversheath 23 in aluminium strip 22 peripheries.In order further to increase the tensile characteristics and the lateral pressure resistant ability of cable, between waterstop 21 and cable core 1, also be filled with aramid yarn 24.

The present embodiment optoelectronic composite cable, in the stranding process, positioning appears in the position for fear of insulated single wire and butterfly optical cable unit, and preforming is carried out in three positions before advancing head that insulated single wire is corresponding with butterfly optical cable, guarantees the distribution of position behind three position strandings.

Use among the utility model composite rope is suitable for that Fiber to the home the FTTH, its solved existing optical cable stretching resistance, lateral pressure resistant power poor, etc. problem, and response country proposes energy-saving and cost-reducing slogan, registering one's residence only needs the single line cable just can solve the demand of home-use electric power transfer, IPTV, voice, network, has bigger application value.

The foregoing description only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this; can not limit protection range of the present utility model with this; all equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection range of the present utility model.
