The 4G era is coming, anti-rat, lightning-proof, long-distance optical cable into cable enterprises to explore the direction

With the advent of the 4G era, the number of base station construction is increasing, and the use of remote optical cables for outdoor coverage is also increasing
.
In this deployment scenario of remote communication, in order to ensure the normal transmission of optical cable channels, how to create remote optical cable components with both rat-proof and lightning protection functions has become the direction
explored by cable enterprises.

At present, the remote cable technology generally adopts a distributed base station architecture, and optical fiber connections
are required between RRU (radio remote module) and BBU (baseband processing unit).
The distance is generally 100~300 meters, one end is located in the base station, and the other end is located in the
bureau.
In this deployment scenario of remote communication, mice and other rats will inevitably cause harm
to the normal transmission of optical cable channels.

Under the current technical conditions, the design of rat-proof optical cables generally uses steel armored pipes
.
It is usually placed in the optical cable sheath, but such a design will also introduce a new problem: because the armored tube can conduct electricity, the transmission tower may be received by the optical cable assembly after the introduction of lightning, so as to transmit along the armored pipe in the optical cable, eventually destroy the optical cable or other equipment, and in severe cases, cause fire
.
Therefore, how to create a remote optical cable assembly with both rat and lightning protection functions has become one of the key exploration directions in the industry in the
future.
