answer:
1. Common fiber optic connectors
LC 、SC 、FC 、ST、 MPO
LC （Lucent connector）
Small square port, often used to connect SFP optical modules and pre-terminated module boxes
SC ( Subscriber Cable)
Snap-in square (large square port), often used in fiber optic transceivers and GBIC optical modules, advantages: standard square connector, direct plug-in, easy to use. Using engineering plastics, high temperature resistance, not easy to oxidize. Cons: Connectors fall out easily
FC（ferrule contactor）
Round threaded, often used for fiber distribution frame&#x
