Abstract

The utility model relates to an optical communication carrier, and particularly discloses an optical cable for providing power supply. The photoelectric composite cable comprises an optical unit and a flame-retardant sheath covering the optical unit; the flame-retardant sheath is internally provided with two symmetrical power units; each power unit comprises a conductor and a coating insulation layer outside the conductor, and an aramid yarn reinforcement piece is filled between the optical unit and the flame-retardant sheath; and the flame-retardant sheath is made of chlorinated polyethylene (CPE). According to the optical communication carrier, optical signals can be transmitted; power supply for the equipment itself can be completed; dual investment and installation cost for laying wire and cable at the same time can be reduced when the wire and the cable are laid; as the aramid yarn serves as the reinforcement piece, the tensile modulus is high, the optical fiber ribbon is not likely to break and is high in stability; and as the cross section of the flame-retardant sheath is rectangular, installation and fixing are easy.

Description

A kind of optoelectronic composite cable

Technical field

The utility model relates to a kind of optical communication carrier, has been specifically related to a kind of optical cable that supply of electric power can be provided.

Background technology

Along with scientific and technical progress and development, the high speed of information transmission has become inexorable trend, and especially clean room and clean room need more information fast and accurately.Yet present stage, optical signal transmission equipment needed power supply, especially clean room and clean room need more optical signal transmission equipment and power supply, make clean room and clean room need a lot of optical communication transmission lines and power line, easily cause repeatedly laying of cable and blocking up of pipeline, urgently a kind of appearance of optoelectronic composite cable, can transmitting optical signal, can complete again the power supply of equipment of itself.

Utility model content

For solving the problems of the technologies described above, we have proposed a kind of optical cable that supply of electric power can be provided, its object: in the time of transmitting optical signal, complete the power supply of equipment of itself.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of optoelectronic composite cable, comprise light unit and be coated on the fire retardant jacket outside light unit, described fire retardant jacket contains two symmetrical power units, described power unit comprises the coated insulation layer outside conductor and conductor, between described light unit and fire retardant jacket, is filled with aramid yarn reinforcement; The material of fire retardant jacket is haloflex (CPE material), and the cross section of fire retardant jacket is rectangle.

Preferably, described light unit is fibre ribbon.

By technique scheme, can transmitting optical signal, can complete again the power supply of equipment of itself, when laying cable, reduced dual investment and the mounting cost of laying wire and optical cable simultaneously.With aramid yarn as reinforcement, because its stretch modulus is high, fibre ribbon easy fracture not like this, stability is high.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the structural representation of a kind of optoelectronic composite cable disclosed in the utility model.

Numeral and the represented corresponding component title of letter in figure:

1. smooth unit 2. fire retardant jacket 31. conductor 32. coated insulation layer 4. aramid yarn reinforcement

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

Below in conjunction with schematic diagram, embodiment of the present utility model is described in further detail.

As shown in Figure 1, a kind of optoelectronic composite cable, comprise fibre ribbon 1 and be coated on the fire retardant jacket 2 outside fibre ribbon 1, fire retardant jacket 2 contains two symmetrical power units, described power unit comprises the coated insulation layer 32 outside conductor 31 and conductor 31, between fibre ribbon 1 and fire retardant jacket 2, is filled with aramid yarn reinforcement 4.

The material of fire retardant jacket 2 is haloflex (CPE material), makes fire retardant jacket have good weather resisteant, resistance to ozone, chemical-resistant resistance, ageing-resistant performance and anti-flammability.

The cross section of fire retardant jacket 2 is rectangle, installs easily fixing.

In the utility model, fibre ribbon 1 is as light unit transmitting optical signal, in fire retardant jacket 2, include the effect that two power units have played equipment self power supply simultaneously, when laying cable, reduce dual investment and the mounting cost of while laying wire and optical cable, prevented from occurring the jam of pipeline.At fibre ribbon 1 coated aramid yarn reinforcement 4 around, because its stretch modulus is high, fibre ribbon 1 easy fracture not like this, stability is high.

Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
