The LC connector, short for Lucent Connector, is a small form factor fiber optic connector originally developed by Lucent Technologies (now part of Alcatel-Lucent).
Designed for high-density applications, the LC connector features compact size and efficient connectivity, particularly in data communications and telecommunication environments.
They connect SFP modules using an easy-to-operate modular jack (RJ) latch mechanism, commonly found in routers.
This push-pull design ensures easy handling while providing a secure, precisely aligned connection that meets TIA/EIA 604 standards.
Key Features
- Compact Design: LC connectors are a miniaturized version of the SC fiber connector, being 50% smaller. They feature a square plastic housing with a 1.25 mm ceramic ferrule.
- High Density: Using LC connectors increases the density of fiber connections in patch panels.
- Versatile Use: Typically, LC connectors are connect fiber to optical modules, often appearing as LC-SC or LC-FC pairs, rather than single LC patch cords.
Dominance in the Market
LC connectors are a versatile choice in the world of fiber optics, catering to a wide range of applications with different versions and options.
Whether you’re dealing with single mode or multimode fibers, there’s an LC connector to fit your needs.
Versions of LC Connectors
- Types: Available in single mode and multimode.
- Polishing: Two polishing types: UPC (blue housing) and APC (green housing with an 8° angle to minimize back reflection).
- Usage:
- Patch cord Connector: Used for simplex and duplex 1.6 to 2.0 mm cable. It features a trigger and standard latch for easy connection and disconnection. Commonly used in LANs, central offices, and patch cords.
- BTW Connector: Used for 0.9 mm fiber, typically on the back side of equipment. Features a finger catch and extended latch for ease of use.
Components and Accessories
The LC connector family includes adapters, attenuators, patch cords, connector modules, panels, and other accessories.
Design Notes
- Networking: Fits into standard SFP+/SFP28 form factors and can be used in QSFP+ or QSFP28 for 40GbE or 100GbE networking.
- Sealing: IP67/68 sealing and waterproof LC connectors are available.
- Attenuation Values: Between 1 and 30 dB.
- Options: Available in duplex, single mode, and multimode.
- Ferrule Size: 1.25 mm.
