The present application relates to the technical field of communication, in particular to a miniature and easy-to-stripping butterfly-shaped photoelectric composite communication optical cable.
With the increasing demand for communication bandwidth and the development of mobile communication 5G, the scale of distributed base stations that the communication industry will continue to use will become smaller, faster, and lower cost. The traditional method usually uses an independent power cable to supply power to the RRU on the top of the tower, and uses an independent optical fiber for signal transmission. Although the above solution can meet the basic transmission requirements, since the cables for power supply and signal transmission are laid independently, multiple constructions are required, which cannot meet the needs of rapid and low-cost 5G construction, and the independent laying of cables takes up more pipeline resources, which is not suitable for tiny objects. There are also some cables that combine power supply and signal transmission cables, such as Chinese patent application CN201920907785.9. It discloses a self-supporting optical fiber cable, the optical transmission conductor part of this cable and the electric transmission conductor part are combined in the same sheath, the magnetic field generated by the electric transmission conductor when transmitting electricity affects the optical transmission part, and it is inconvenient to strip the optical fiber and the electrical transmission conductor from the photoelectric separation port for on-site application, and there is a risk of damaging the optical fiber when separating the electrical transmission conductor part.
