Description

The hybrid fiber optical cable

Technical field:

The utility model relates to the optical fiber cable that a kind of photosignal transmission field is used.

Background technology:

At present, optical cable and cable have been widely used in every field.But all there are a defective in existing optical cable or cable, promptly can only distinguish transmitting optical signal or electric signal.And when many occasions need be carried out the transmission of light signal and electric signal simultaneously, can only insert separately optical cable and cable respectively, need to increase corresponding separately light, electric equipment/module etc. simultaneously.Therefore system complex, huge is not easy to the miniaturization of system and integrated.

For example along with the development of optical communication technique, the application of optical fibre device more and more widely, optical fibre device now is in the system of reality uses, particularly between jumbo optical cross-connection equipment, debug, when safeguarding, in the face of thousands of optical fibre devices, the position, another port of finding same optical fibre device quickly and accurately is one of key that improves system works efficient.Therefore for existing optical fibre device, need provide a kind of mode of electric system to cooperate location and conversation.And simple lead-in cable, problem such as can cause system cost to rise and equipment is various.This is that system operator is difficult to accept.

Summary of the invention:

The purpose of this utility model is exactly to provide a kind of hybrid fiber optical cable in order to overcome the above problems, and carries out the transmission of light signal and electric signal simultaneously, is easy to the miniaturization of system and integrated.

The utility model realizes that the scheme of above-mentioned purpose is: a kind of hybrid fiber optical cable; comprise cable outer sheath and at least one optical fiber that is positioned at cable outer sheath; the center of optical fiber is a fibre core; the skin of fibre core is a covering; it is characterized in that: also have at least two conductor wires in the cable outer sheath, there is insulating protective layer in the outside of conductor wire.

Adopt the beneficial effect of above scheme: optical fiber can transmitting optical signal, and conductor wire can transmit weak electric signal and low-voltage power supply, and the system of can be provides a kind of media of photoelectric interaction; And optical fiber, electric wire is in the same cable, and system is simple, is easy to integrated.

Description of drawings:

Fig. 1 is the cross sectional representation of hybrid fiber optical cable;

Fig. 2 is the longitudinal section synoptic diagram of hybrid fiber optical cable;

Fig. 3 is the situation synoptic diagram when inserting photodiode.

Embodiment:

Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.

Embodiment one: see shown in Fig. 1 or 2 that a fibre core 5 is arranged in the cable outer sheath 1 of this hybrid fiber optical cable, the fibre core 5 outer covering oversheaths that are with optical fiber, 2 is the covering of optical fiber among the figure, 5 is the fibre core of optical fiber, and optical fiber can be single-mode fiber, also can be multimode optical fiber; The optical fiber that comprises in the optical cable can be single, also can be many.3 is intermediate protective layer.Conductor wire 6 is a kind of micro metal electric wire among Fig. 1.4 is the insulating protective layer of metal cords.

This optical cable very easy to use, with the joints of optical fibre is example, if light emitting diode 16 is inserted at the two ends at two terminal adapter place conductor wires 6, during use conductor wire 6 is linked to each other with power supply 36, then light emitting diode can be luminous, then can recognize the lit fiber device easily, be exactly the optical patchcord made from this hybrid fiber optical cable as shown in Figure 3, and wherein 14 is joints of optical fibre.Equally, if connect with the mains/communication module, both sides can converse.

The utility model comprises multiple single fiber or multiple fiber cables such as layer-stranding cable, slotted core cable, optical fiber ribbon cable and beam tube type cable applicable to various inside cables, outdoor optical cable.
