CompTIA Network+ (N10-009)Network ImplementationEasy
A technician is terminating a single-mode fiber run to connect a small form-factor SFP transceiver in a high-density patch panel. Which connector type is most commonly used for this application?
- AST connector
- BBNC connector
- CLC connector
- DRJ45 connector
Show answer & explanationAnswer & explanation
Correct answer: C. LC connector
The LC (Lucent Connector) is a small form-factor fiber connector widely used with SFP and SFP+ transceivers because its compact size allows higher port density on patch panels and switches.
Why the other options are wrong
- A. ST connectors are older, larger bayonet-style connectors, less common with modern SFP modules.
- B. BNC connectors are used for coaxial cable, not fiber optics.
- D. RJ45 connectors are used for copper twisted-pair Ethernet, not fiber.
LC Fiber Connector
A small form-factor fiber optic connector commonly paired with SFP/SFP+ transceivers for high port density.
- Smaller than SC and ST connectors
- Snap-in latch design
- Standard for modern SFP-based fiber links
Memory trick: 'LC' = Little Connector fits Little SFP slots.
