The invention relates to a photoelectric composite cable, which combines optical fibers and coaxial-cables and can transmit optical signals and electric signals in the same cable at the same time. A central conductor of the photoelectric composite cable is used for transmitting the signals, and an insulation layer is used for insulating the central conductor from N layers of shielding layers; the central conductor, the insulation layer, the N layers of shielding layers and an insulation sleeve form an integral coaxial cable. The optical fibers are used for transmitting the signals, and insulating filler plays the role of fixing the optical fibers; therefore, the coaxial cable, the optical fibers, the insulating fillers and the insulating sleeve form the photoelectric composite cable.
Description
technical field [0001] The invention belongs to the technical field of cable broadcasting and television, and is a photoelectric composite cable in which an optical fiber and a coaxial cable are combined together, which can simultaneously transmit optical signals and electrical signals in the same cable. Background technique [0002] At present, various regions are actively promoting the integration of the three networks. Radio and television is using the broadband advantages of the original coaxial cable and adopting various technologies to carry out network transformation. However, it is necessary to transmit the signal downward and transmit the signal back on a coaxial cable, which will reduce the carrying capacity of the network and affect the quality of signal transmission. [0003] The advent of the photoelectric composite cable has reduced the transmission pressure of the coaxial cable, solved the problem of signal transmission in the access network, and made full pre...
