Optical patch cable duplex LC–SC 50/125 µm OM3 20 m

Duplex multimode optical patch cable with LC connector on one end and SC connector on the other, designed with a 50/125 µm core/cladding and OM3 classification. At 20 m length, this LC–SC patch cord supports laser-optimized multimode transmission for high-speed short-reach links in local area networks, data centers and telecommunication patching. The cable provides duplex connectivity for transmit and receive channels and is suitable for interconnecting active equipment, patch panels and distribution frames where OM3 performance is required.

Advantages

This OM3 duplex LC–SC cable delivers consistent multimode performance for short-reach high-bandwidth signals while maintaining compatibility between LC and SC interface types. The 50/125 µm fiber core supports laser-optimized wavelengths, reducing modal dispersion for improved bandwidth over typical multimode links. The duplex configuration ensures reliable transmit/receive pairing, and the 20 m length covers common rack-to-rack and room-to-room patching distances without additional splices or intermediate connectors.

Suitable for

• Short-reach multimode connections in data centers and server rooms
• LAN backbone and inter-rack patching
• Connecting equipment with LC and SC ports (switches, transceivers, patch panels)
• Telecommunication patching cabinets and distribution frames

Key specifications

• Fiber type: Multimode, 50/125 µm core/cladding
• OM rating: OM3 (laser-optimized multimode)
• Connector configuration: Duplex LC to SC
• Length: 20 m
• Polish/type: Factory-terminated multimode connectors with standard ferrule polish
• Application: Short-reach high-bandwidth links (LAN, data center, telecom)

How to use

Verify that both ends are clean and free of dust before insertion. Insert the LC connector into the LC-style port and the SC connector into the SC-style port until each connector latches or seats securely. Route the cable to avoid sharp bends and maintain the minimum bend radius recommended for 50/125 µm multimode fiber. For duplex operation, ensure the correct orientation of transmit and receive channels on connected devices. When removing the cable, unlock or unlatch connectors first and pull from the connector bodies rather than the fiber jacket.

Usage recommendations

Use a fiber inspection scope and dry lint-free wipes to clean connectors prior to connection. Avoid tight coils and protect the cable from crush or abrasion. For optimal performance in data center environments, pair OM3 multimode patching with compatible multimode transceivers and verify link performance with appropriate fiber test equipment after installation.
