[0002] The SFP optical module is a hot-swappable small-package module with an SFP package. The maximum rate can reach 10.3G and the interface is LC.

[0003] The unlocking structure of the SFP optical module on the market is composed of a handle, a lock tongue and a spring. The handle drives the spring to extend and contract, and then the spring drives the lock tongue to pop out and contract. In daily use, the contraction and extension of the spring are unstable, resulting in unsatisfactory pop-up and contraction effects of the lock tongue. After the handle is turned to the specified position, the spring does not move, the lock tongue is not retracted into the SFP optical module, and the SFP optical module cannot be removed from the chassis. The unlocking structure using a spring has a high failure rate. Utility Model Content
