Abstract
The invention relates to a photoelectric hybrid cable for wireless radio remote. The photoelectric hybrid cable is formed by optical unit portions, an electrical unit portion, a center reinforcement member, a shielding layer and an outer sheath. The center reinforcement member is arranged in the center of the hybrid cable; the optical units and the electrical unit as well as a possible filling rope are subjected to SZ stranding to form a cable core with the center reinforcement member as the center. The cable core is externally wrapped with a wrapping belt, the shielding layer and the outer sheath in sequence. Each optical unit is formed by a tight tube fiber, a helix tube armor, a reinforcement member and an optical unit sheath. The tight tube fiber is formed by a coated fiber and a tight tube coating layer wrapped outside the coated fiber. The tight tube fiber is arranged in the center of the optical unit. The tight tube fiber is externally wrapped with the helix tube armor, the reinforcement member and the optical unit sheath longitudinally and sequentially. The electrical unit is formed by a conductor wrapped by an insulating layer. The shielding layer is formed by one or more metal tapes, one or more metal braided layers, or a combination structure of the metal braided layer and the metal tape.
Description
Technical field
The present invention relates to communications optical cable field, particularly relate to a kind of remote radio head photoelectric mixed cable being applied to Wireless distributed base station.
Background technology
Along with the fast development of wireless access, China so all greatly developing 3G and 4G all over the world, this needs to build a large amount of Wireless distributed base stations to allow wireless signal can cover each corner, signal between past base station connects by coaxial cable, there is transmission bandwidth capacity little, volume is large, the shortcoming of price, the needs of smart antenna in 3G and 4G antenna in the future can not be met, simultaneously RRU as far-end active module embedded therein away from calculator room equipment, its powerup issue will become the focus in networking, a kind of light harvesting fiber communication and electric power transfer is researched and developed imperative in the remote radio head photoelectric mixed cable of one under such environmental background.
Summary of the invention
The object of the present invention is to provide a kind of light harvesting fine with transmission of electricity copper cash in the remote radio head photoelectric mixed cable that one, good mechanical property, good bending property, anti-flammability are strong and anti-lightning strike, meet and between adaptation base station and base station and requirement.
Solution of the present invention is: a kind of remote radio head photoelectric mixed cable, be made up of light cell mesh, electric unit part, central reinforce member, screen, oversheath, central reinforce member is arranged on mixing cable center, light unit and electric unit and presumable gasket for packing " SZ " centered by central reinforce member are twisted into cable core, cable core outer coated band, screen, oversheath successively, light unit is made up of tight tube fiber, helix tube armouring, reinforcement, light unit sheath.Tight tube fiber is made up of coated fiber and the tight cover coating be coated on outside coated fiber, and tight tube fiber is arranged on light unit center, tight tube fiber longitudinally coated helix tube armouring, reinforcement and light unit sheath successively outward.Electric unit is made up of the conductor of coated insulation layer.Screen can be made up of the combining structure of one or more metal tapes, one deck or multiple layer metal braid or wire sheathing and metal tape.
Owing to adopting such scheme, advantage of the present invention is: the present invention adopts screen, reduces the induced current grade that lightning produces, minimizes the general electromagnetic noise that conductor brings simultaneously; Light unit and electric unit twisted synthesizing cable, can solve the problems such as broadband access, equipment electricity consumption, Signal transmissions; Light unit adopts helix tube armouring, for light unit provides excellent stretch-proof and lateral pressure resistant ability.
