A New Photoelectric Composite Cable

technical field

The utility model relates to a cable, in particular to a novel photoelectric composite cable.

Background technique

Today, the requirements for communication distance and capacity are getting higher and higher, and the traditional pure copper cable solution is becoming more and more challenging in terms of transmission distance and transmission capacity.

The new type of photoelectric composite cable has derived many applications, such as long-distance communication power supply system, home audio and video high-definition transmission, etc.; in these applications, because the copper cable is only responsible for power transmission and low-frequency signal transmission, the electromagnetic interference can be ignored, and high-speed signals pass through the optical fiber. Transmission, so the photoelectric composite cable does not require special treatment for copper cables, and the signal transmission specifications in each copper wire do not have clear requirements. Such a structure will cause serious electromagnetic interference when the copper wire also needs to transmit high-frequency signals, which is not conducive to the extension of the transmission distance.
