With the continuous development and improvement of 5G communication technology, the optical cable used between the traditional mobile communication base stations is no longer applicable in the face of new mobile communication technology standards. The 5G communication technology constructs an ultra-dense network, which requires that the power requirement of transmission equipment of each large 5G communication base station is increased, and the transmission equipment and a core network area are increased to transmit electric signals. Conventional outdoor communication cables are: the GYTS type and the GYTA53 type can only transmit optical signals, cannot transmit electrical signals, and cannot meet the requirements of the 5G communication technology. In a traditional mobile communication network, the transmission of photoelectric signals between macro base stations is separated, and network deployment, operation and maintenance are completed mainly by a manual mode. However, this has the following disadvantages:

(1) corresponding labor cost and technical cost are consumed for manual network deployment and operation and maintenance. Particularly, when the optical cable and the electric unit are separated, the cost is high.

(2) Increasing the raw material cost. Under the same condition, the raw material cost for separating the optical cable and the electric unit is more than that of the photoelectric composite cable.

(3) Network and power optimization is also not ideal. The optical cable and the electric unit are separated, and the running cost is increased.

In order to ensure the reasonable utilization of pipeline resources and the transformation planning of future communication base station equipment in the 5G construction process and save the construction cost, the reduction of the outer diameter of the optical cable is important under the condition of limited pipeline space.
