Which term refers to a compact transceiver used to connect fiber optic links, commonly installed in switches and routers?

• A. Small Form-factor Pluggable Transceiver
• B. USB-C Transceiver
• C. RJ-45 Module
• D. Optical Transceiver

Answer: (A)

The main idea is the compact, hot-swappable transceiver that plugs into switches and routers to connect fiber links. This is the Small Form-factor Pluggable Transceiver. It’s designed to be inserted into a dedicated SFP slot on network gear, and it enables fiber connectivity with the flexibility to swap modules for different fiber types and distances (for example, SX for short-range multimode, LX for long-range single-mode). Because of its small, plug-in form factor, it’s widely used to modularly extend and customize fiber connections across devices. Other terms don’t fit as precisely: a USB-C transceiver is for USB data paths, not standard fiber networking; an RJ-45 module is for copper Ethernet through twisted-pair cables; an optical transceiver is a broad term that doesn’t specify the compact, pluggable form factor used in routers and switches.
