Optical-electrical composite cable is suitable for use as a transmission line in broadband access network systems. It is a new type of access method that integrates optical fiber and power transmission copper wire, and can solve the problems of broadband access, equipment power consumption and signal transmission.

[0003] The technical solution commonly used in the prior art for composite optical cables is to glue the branch cables together with glue or sheath ropes, and then directly tear them off when in use. When the optical cable branches are torn off, the sheaths of the adjacent optical cable branches may be torn off, or uneven barbs may appear at the torn ends, which wastes resources. When a different type of cable needs to be replaced or the corresponding cable is damaged, the entire composite optical cable needs to be replaced, which is relatively cumbersome. In addition, the round composite optical cable in the prior art is relatively soft, and is easy to bend when the electrical conductors need to be laid through a pipe, and is not easy to pass through the wire pipe.
