Description

Waterproof box for optical cable Technical Field The utility model relates to the technical field of optical cable switching, in particular to an optical cable waterproof box. Background In the prior art, fiber optic cables are widely used. The optical cable mainly realizes the transmission of optical signals, and plays a key role in a plurality of fields as a communication transmission medium. The optical cable has wide application fields, utilizes the optical fiber to transmit optical signals, converts the optical signals into optical pulses, transmits the optical pulses in the optical fiber in a total internal reflection mode, and converts the optical signals back into electric signals after reaching a destination, thereby realizing quick and reliable information transmission. The optical cable has the advantages of high bandwidth, long transmission distance, low loss, strong anti-interference capability and the like, so that the optical cable becomes the first choice technology of modern communication. But in some situations, the cable needs to be switched during use. Such as long haul transmission relays and single multimode fiber optic conversions, etc. The optical fiber or the connector is exposed at the switching position, so that the optical fiber or the connector is easily damaged due to the influence of external environment, and particularly, the performance of signal transmission and the like can be greatly influenced after the optical fiber or the connector is contacted with water, so that the optical cable waterproof box is required to protect the switching position. Disclosure of utility model The present utility model aims to solve at least one of the technical problems existing in the prior art.
