Embodiment 2

[0043] The hybrid cable disclosed in embodiment 2 is an optical fiber coaxial hybrid cable, and its structure is as follows figure 2 As shown in , the hybrid cable is composed of a coaxial cable unit 10 and an invisible optical cable 20. The core of the invisible optical cable 20 is a covered optical cable 22, and a reinforcing member 21 is provided on both sides of the covered optical cable 22. The invisible optical cable 20 is composed of the wire optical cable 22 and the two above-mentioned strengthening members 21 wrapped in transparent nylon. The above-mentioned invisible optical cable 20 is arranged on the same side of the above-mentioned coaxial cable unit 10, and the structure of the above-mentioned hybrid cable is flat. The damage to the cables caused by laying construction.

[0044] The optical fiber coaxial hybrid cable adopts the access method of coaxial dual optical fibers, which not only meets the requirements of radio and television coaxial optical fiber doubl...

Embodiment 3

[0047] The hybrid cable in this embodiment is a coaxial air-blown hybrid cable, such as image 3 As shown in , it consists of a coaxial cable unit 10 and an air-blown micro-tube 30, the air-blown micro-tube 30 contains at least one core air-blown micro-cable 31, that is, the optical cable unit of the hybrid cable contains at least one core air-blown The microcable 31 , the air-blown micro-cable wraps the air-blown microtube 30 outside, and the coaxial cable unit 10 and the air-blown microtube 30 are wrapped by the outer sheath 1 . In addition, the coaxial cable unit 10 and the air blowing microtube 30 are arranged side by side, and the structure of the hybrid cable is flat.

[0048] The cable is used for coaxial access and the air-blown micro-pipe 30 is reserved in the cable. The one-time laying not only reduces the construction cost, but also provides pipeline resources for future FTTH. The fiber is sent to the user's home.

[0049] The hybrid cable is composed of a coaxial...

Abstract

The invention relates to a mixed cable containing a coaxial cable. The mixed cable comprises an internal structure of the mixed cable and an outer sheath coating the outer layer of the internal structure of the mixed cable. At least one ripping cord is arranged between the internal structure of the mixed cable and the outer sheath. The internal structure contains a coaxial cable unit and at least one optical cable unit; and after the coaxial cable unit and the optical cable unit are twisted into a cable unit, the outer sheath sleeves the cable unit. The mixed cable can be used as a transmission line in a broadband access network system and a novel access way is realized. The mixed cable is integrated with the fiber, the coaxial cable, and pair twisted cables; and problems of broadband access and signal transmission can be solved. The mixed cable can be mainly applied to a cable TV network and a broadband access network system. Moreover, different combination units of several kinds of transmission signal lines, various access modes of the broadcast and TV system can be realized.

Description

technical field [0001] The invention belongs to the technical field of communication, in particular to the optical fiber coaxial pair twisting hybrid technology, and in particular to a hybrid cable containing a coaxial cable. Background technique [0002] A coaxial cable is a cable composed of two conductors. The central wire of the coaxial cable is used to transmit signals. The metal shielding net plays two roles: one is to provide a current loop for the signal as a common ground wire for the signal, and the other is to provide a current loop for the signal. It is used as a shielding network for the signal to suppress the interference of electromagnetic noise on the signal. The central wire and the shielding net are interposed between the semi-foamed polypropylene insulating layer, which determines the transmission characteristics of the cable and effectively protects the middle wire. The reliable physical characteristics of coaxial cables can provide excellent audio and v...
