Description

Technical Field

[0001] This application relates to an adapter and connector assembly. Background Technology

[0002] Traditional SFP socket connector modules typically include an SFP socket terminal assembly and a metal shielding cage assembly. The metal shielding cage assembly forms a mating cavity for the insertion of the optical module plug connector. When the SFP socket connector module fixed on the circuit board inside the electronic device is uniquely determined, the size and length of the mating cavity are also fixed. Therefore, it can only mate with an optical module plug connector that uniquely matches its length. When a shorter optical module plug connector exists, mating cannot be completed. Therefore, improvements are necessary to address this issue. Summary of the Invention
