Description
Technical field
The utility model relates to the indoor type photoelectric mixed cable that one is applicable to wireless radio remote unit (RRU), belongs to optical fiber cable field.
Background technology
Along with the development of data communication and multimedia service, the requirement of mobile subscriber to digital mobile device communication speed, speech quality and intelligent behaviour etc. improves constantly, and rapidly increases, directly promoted the 3G even extensive commercialization of 4G technology to the requirement in broadband.The distributed base station of application Remote Radio Technique is a large feature of 3G network, the Base-Band Processing of traditional macro base station is separated with radio frequency part, be divided into Base-Band Processing and remote radio two equipment, adopt Fiber connection between, RRU volume is little, RRU can solve the long range propagation loss problem of feeder, improves the flexibility of Plan and design.
My company proposes a kind of indoor type photoelectric mixed cable of applicable wireless radio remote unit under above-mentioned background, radio base band control RS and remote radio RRU passes through Fiber connection therebetween, feeder loss can be reduced, reduce the power requirement of power amplifier, thus reduce base station equipment cost; This cable has two electric units simultaneously, and pulling out power line by inside of base station is that RRU powers, and this cable can reduce material and laid down cost, reduces to lay difficulty, avoids feeder line too much, the drawback of wiring confusion, will become the first-selection connecting near-end machine and remote termination.
Utility model content
The purpose of this utility model is the indoor type photoelectric mixed cable providing wireless radio remote unit, meets the user demand of radio base band control RS and radio frequency remote unit RRU dragging optical cable therebetween, simultaneously for radio frequency remote unit RRU is powered.
The technical solution adopted in the utility model is: the indoor type photoelectric mixed cable of wireless radio remote unit, be made up of cable core and the part such as the band that blocks water, braid, oversheath be coated on outside cable core, cable core is made up of single fiber cable, copper conductor, water resistance aramid fiber, cable core adopts the stranded mode of spiral, block water band, screen is coated on outside cable core successively, be respectively optical cable provide block water, shielding action, sheath adopt flame retardant polyolefin jacket material.
Of the present utility modelly to have the following advantages:
The indoor type photoelectric mixed cable of 1, described wireless radio remote unit adopts single fiber cable as Optical Fiber Transmission unit, in single fiber cable structure, play the hard-pressed bale layer of cushioning effect and the sheath of single fiber cable and all adopt low smoke and zero halogen material, and use aramid fiber to strengthen single fiber cable unit, thus ensure that the fire resistance of cable core, make it have good mechanical performance and environmental performance simultaneously.
The indoor type photoelectric mixed cable of 2, described wireless radio remote unit adopts single fiber cable as Optical Fiber Transmission unit, and single fiber cable is easy to construction and continues, and has good defencive function to optical fiber.
The indoor type photoelectric mixed cable of 3, described wireless radio remote unit, electric unit adopts and meets the 5th kind of flexible conductor in GB/T3956-2008, makes this cable have very little bending radius.
The indoor type photoelectric mixed cable of 4, described wireless radio remote unit, adopts water resistance aramid fiber to fill cable core gap, ensures the tension of this cable, lateral pressure resistant, block-water performance.
The indoor type photoelectric mixed cable of 5, described wireless radio remote unit, the outer outer cladding one deck of cable core blocks water band, ensures the block-water performance of this cable.
The indoor type photoelectric mixed cable of 6, described wireless radio remote unit, blocks water between band and outer jacket and has layer of metal screen, is mainly used to reduce the induced current grade that lightning produces, also can be used to minimize the general electromagnetic noise that conductor brings.
The indoor type photoelectric mixed cable of 7, described wireless radio remote unit, protective cover material adopts flame retardant polyolefin jacket material, makes it have good fire resistance.
