What types of connectors are used in fiber optic patch cords?

Common connector types for fiber optic patch cords include LC, SC, FC, ST, MPO, MTRJ, MU, E2000, DIN, and others. Each connector differs in structure, dimensions, and application scenarios.

• LC Connector: 

Compact size, easy insertion/removal, widely used in SFP optical modules and high-density data centers.

• SC Connector: 

Square housing with push-pull insertion, commonly used in routers, switches, and GBIC optical modules.

• FC Connector: 

Metal sleeve with screw-locking mechanism, frequently employed in optical distribution frames (ODF) and surveillance systems.

• ST Connector: 

Circular housing with bayonet-style twist-lock, prevalent in optical distribution frames and legacy equipment.

• MPO Connector: 

Multi-fiber connection, suitable for high-density cabling, commonly used in 40G/100G networks and data centers.

• MTRJ Connector: 

Transceiver-integrated, dual-fiber transmission, primarily used in telecommunications and data network systems.

• MU Connector: 

Miniature design, suitable for high-density connections.

• E2000 Connector: 

Features a dust cover, high security, often used in high-end equipment.

• DIN connectors: 

Less common, primarily used in specific industrial equipment.

These connectors are typically selected based on device interface requirements and are not directly interchangeable.
