Fiber Optical Duplex Cable InLine 88639P 20m LC/SC 50/125µm OM4

The InLine Fiber Optical Duplex Cable 88639P 20m LC/SC 50/125µm OM4 is a multimode duplex cable designed for high-speed data transmission over short to medium distances. With LC connector on one end and SC connector on the other, 20 metres of OM4 graded 50/125µm fiber provides low attenuation and enhanced modal bandwidth for modern LAN, data centre and enterprise networking environments. The cable supports full duplex communication and is suitable for use in patching, equipment interconnects and structured cabling systems.

Advantages

This OM4 multimode fiber cable delivers higher bandwidth and improved signal integrity compared with lower-grade multimode fibers, allowing reliable 10 Gigabit and higher-speed connections where distance and performance demands are significant. The duplex configuration enables simultaneous transmit and receive channels, while the LC-to-SC connector combination offers compatibility with a wide range of switches, transceivers and patch panels. The 20 m length provides flexibility for rack-to-rack and room-to-room installations without the need for splices.

Suitable for

• Data centre patching and horizontal cabling
• Network equipment interconnects (switch to transceiver)
• Server room and telecom wiring where LC and SC ports are present
• Short to medium distance multimode links supporting 10 Gbps and above

Key specifications

• Fiber type: OM4 multimode
• Core/cladding diameter: 50/125 µm
• Connector types: LC (one end) to SC (other end)
• Configuration: duplex (two fibers)
• Length: 20 m
• Typical use: indoor patching and equipment interconnect

How to use

Inspect both connectors and the cable jacket for visible damage before installation. Align the LC and SC connectors with the corresponding ports and insert until a secure click or seating is achieved; do not force connectors if resistance is encountered. Route the cable to avoid sharp bends and maintain the manufacturer’s recommended minimum bend radius to preserve optical performance. For permanent installations, use appropriate cable management and strain relief to prevent stress on the connectors and fiber.

Recommendations

Handle connectors by their bodies and always replace protective dust caps when connectors are not mated. Clean fiber endfaces with a suitable fiber cleaning tool before connecting to minimise insertion loss. For links carrying high-speed signals, verify link performance with appropriate test equipment after installation and ensure compliance with system transceiver specifications and channel loss budgets.
