Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an optical/electrical composite core wire with a connector.

In a conventional optical/electrical composite cable, as shown in FIG. 1, a former fiber cable unit 2 in which a plurality of optical fiber cores 1 are assembled, and an electric cable unit 4 in which a plurality of electrical core wires 3 are all assembled. It had a structure in which a plurality of units were twisted 9 around a central tensile strength member 5, and a cable sheath 7 was coated on the outer periphery of the twisted unit with a pressing layer 6 interposed therebetween.

When such an optical/electrical composite cable is used for relatively short distance wiring such as inside a device, the signal transmission system includes electrical connections at both ends of each optical fiber core 10, as shown in Figure 2. - Connect an optical converter (hereinafter referred to as an ``converter'') 8 and an optical/electrical converter (hereinafter referred to as an OA converter) 9, and connect these E10 converters 8 and O/E converters 9. In some cases, the driving power source 10 is installed at either the transmitting end or the receiving end, and power is supplied to the far end via the electrical core wire 3. This is because there is an advantage that the power source IO only needs to be installed in one location.

In such a structure, the number of V is equal to the number of optical fibers l.
The O converter 8 and the OA converter 9 are required 9, and the power supply system for driving these converters 8 and 9 is to connect all Elo converters 8 and OA converters with one cable using one power supply line. A batch power supply method that supplies power to the device 9 all at once, and a paired V
Each pair is supplied to O converter 8 and 07A converter 9 individually.
There are two types of individual power supply systems.

However, in the case of the batch power supply method, the driving error
Variations in the number of 10G converters 8 and 0β converters 9 require adjustment of the supply voltage or supply current, which is a technically difficult drawback.

On the other hand, in the case of the individual power feeding method, the above-mentioned problems are eliminated, but separate power feeding lines are required, and therefore, wiring for the optical fiber core wire and wiring for the electrical core wire for power feeding are required. There is a drawback that the wiring is congested. Further, in this case, there is a drawback that the number of mutual connections of optical fibers I, δ, and V and the number of mutual connections of electrical core wires increases, resulting in a congestion of connection ends.

An object of the present invention is to provide a connector-side optical/electrical composite core wire that can solve problems of voltage/current fluctuations and congestion of wiring and connection parts.

The optical/electrical composite core wire with a connector according to the present invention has one core in the center.
The core optical fiber is arranged and two wires are placed on both sides or around it.
