Embodiment 1

[0021] Embodiment one: referring to shown in accompanying drawing 1, a kind of shielded photoelectric broadband hybrid cable comprises a shielded six types of copper cables (STP Cat.6), and this shielded six types of copper cables are separated by four pairs of twisted wires 2 and four pairs The cross skeleton 3 of the twisted pair wire 2 and the shielding layer 8 and the outer sheath 1 wrapped around it from the inside to the outside in sequence. The placement of the four pairs of twisted wires 2 meets the standard Category 6 copper cable standard. The shielding layer 8 is specifically made of metal braided mesh and metal-plastic composite tape, and each pair of twisted wires 2 is composed of a core 4 and an insulating layer 5 . Moreover, a central hole 6 is opened in the center of the cross frame 3 along the axis (ie, along the length direction of the cable), and two optical fibers 7 pass through the central hole 6 . The cross frame 3, the insulating layer 5 and the outer s...

Embodiment 2

[0024] Embodiment two: referring to shown in accompanying drawing 2, a kind of shielded photoelectric broadband hybrid cable, differs from embodiment one in that: it includes a shielded seven types of copper cables (Cat.7STP), this shielded seven types of copper cables The arrangement of the four pairs of twisted wires 2 meets the standard seven-category copper cable standard. Others are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The present invention relates to a kind of shielding photoelectric broadband hybrid cable. The cable includes a six-or-seven-kind shielding copper wire which further includes four pairs of twisted-pair wire[2], cross frames[3]to isolate the four pairs of twisted-pair wire and shielding layers[8] and external sheath[1] covering the wires from inside to outside; the every twisted-pair wire[2] is composed of wire core[4] which is covered of shielding layer; the cable has following characters: the said cross frame[3] has a central hole[6] along its axis, and the central hole[6] is threaded of fiber[7] or fiber core. The present invention can transmit both electric signals and optic signals, which will not interfere the transmission of each other. The present invention also has the advantages of simple and unique structure, less material consumption, small volume, combustion and combustion-supporting invalid and high continuous-working temperature.

Description

technical field [0001] The invention relates to a photoelectric broadband hybrid cable, which is a hybrid cable of a shielded six-category copper cable (STP Cat. 6) or a shielded seven-category copper cable (STP Cat. 7) and an optical cable, and can simultaneously transmit optical signals and electrical signals. Background technique [0002] With the continuous development of information communication, the demands of users for information are increasing rapidly, such as multimedia communication using computers, video telephony and video conferencing. At present, users mainly access broadband through twisted-pair copper cables, but the limitations of its transmission capacity have been exposed. Therefore, high-capacity fiber-to-the-home is an inevitable choice for future broadband services. But at present, the price of optical fiber and the compatibility and cost of matching terminal equipment are still high, so it will take some time to realize all fiber-to-the-home. Theref...
