Problems solved by technology

The optical-electrical hybrid cable for RRU in YD / T 2289.3 is suitable for indoor and outdoor short-distance vertical deployment. It uses tight-buffered optical fiber as the optical unit, and has no advantages in field termination, cost, and laying efficiency.
The indoor distributed antenna system uses the feeder line, which has large size, complex lines, difficult network monitoring and management, and large transmission loss at medium and high frequencies

Abstract

The invention discloses a photoelectric hybrid cable for small base stations, which comprises an outer sheath, two butterfly optical cables and two power wires. The two power wires are arranged in parallel; one butterfly optical cable is arranged on one side of the two power wires in a recess of the contact part of the two power wires, and the other butterfly optical cable is arranged on the otherside of the two power wires in the recess of the contact portion of the two power wires; the two butterfly optical cables and the two power wires are covered with the outer sheath. The photoelectrichybrid cable is suitable quickly and simply deploying 4G and 5G small base station networks, and allows digital coverage of indoor wireless signals and dense coverage of outdoor wireless signals.

Description

technical field [0001] The invention relates to a photoelectric hybrid cable, in particular to a photoelectric hybrid cable for a small base station. Background technique [0002] With the maturity of 4G technology and the development of 5G technology, more and more small base stations are used for wireless signal coverage in the field of wireless communication. At this time, a photoelectric hybrid cable is needed to connect the baseband processing unit and Radio frequency remote unit. At present, macro base stations are used for outdoor wireless signal coverage, and photoelectric hybrid cables for wireless radio remote units as specified in YD / T 2289.3 are used in macro base stations. This product uses tight-sleeved optical fibers as optical units; indoor wireless signal coverage A distributed antenna system is used, and a feeder is used in a distributed antenna system. This product has a large size and has a large transmission loss at medium and high frequencies. The op...
