AI Technical Summary

Technical Problem

Existing fiber optic transceiver interface structures are prone to breakage due to external pulling, lack sealing protection, and have no anti-misinsertion design, leading to equipment failure, signal attenuation, and communication interruption.

Method used

The fiber optic transceiver interface protection structure with anti-misinsertion latch is adopted, including upper box, lower box, sealing mechanism and limiting mechanism. Through the cooperation of slot, sealing ring and anti-misinsertion latch, the interface is stably fixed, sealed and protected and prevented from misinsertion.

Benefits of technology

It extends the service life of the interface lines, prevents dust and moisture from entering, avoids the interface from falling off due to external force and mis-insertion, and ensures communication continuity.
