Explanation

SC/PC connectors are the standard fiber interface on the Huawei MA5680T's GPBD (GPON OLT) board. SC (Subscriber Connector) is a push-pull square-body connector widely adopted in telecom/PON deployments, and the PC (Physical Contact) polish provides sufficient return loss performance for GPON line-side interfaces on this platform.

Why the distractors are wrong:

• A (LC/PC) - LC is a smaller "little connector" form factor; the GPBD board physically uses SC-sized ports, not LC.
• B (FC/PC) - FC is a threaded, screw-on connector primarily found in lab/test equipment, not in OLT line boards.
• D (LC/APC) - Wrong on two counts: incorrect body size (LC instead of SC) and APC (angled ferrule) is not the polish spec on the GPBD's SC ports.

Memory tip: Think "Standard Choice for OLT" - SC/PC is Huawei's go-to connector for GPON board ports on the MA5680T family. If you see LC, think "lab or small SFP"; if you see FC, think "field test gear" - neither belongs on a GPBD slot.
