InLine Fiber Optical Duplex Cable LC/ST 50/125µm OM3 0.5m

The InLine Fiber Optical Duplex Cable LC/ST 50/125µm OM3 0.5m is a short-length multimode fiber patch cable designed for full-duplex data transmission between networking devices. It combines an LC connector on one end and an ST connector on the other to allow connections between equipment with different port types. With a 50/125µm core/cladding diameter and OM3 multimode grading, the cable supports high-speed links in data centers, LAN backbones, and network closets over short distances.

Advantages

This duplex fiber cable provides low insertion loss and stable transmission for multimode networks. The OM3 specification enables higher bandwidth and reliable performance for 10 Gbps applications at short range, while the LC and ST connector combination offers flexibility for connecting modern transceivers and legacy equipment without adapter modules. The compact 0.5 m length reduces excess slack and improves cable management in dense racks and patch panels.

Suitable for

• Short-distance fibre links in data centers and server rooms
• Connecting switches, routers, media converters, and transceivers with LC or ST ports
• LAN backbone and horizontal patching where multimode OM3 is specified
• Environments requiring tidy cable management and minimal bend radius stress

Key specifications

• Fiber type: Multimode OM3
• Core / cladding diameter: 50/125 µm
• Connector A: LC (duplex)
• Connector B: ST (duplex)
• Cable length: 0.5 m
• Duplex configuration for simultaneous transmit and receive
• Typical application: Short-range high-speed multimode links (e.g., 10 Gbps)

How to use

Identify the LC and ST ports on the devices to be connected and ensure both ends are clean and free of dust before mating. Insert the LC connector into the LC port until it clicks, and align and push the ST connector into the ST bayonet socket, twisting the connector sleeve until it locks. Route the 0.5 m cable to avoid tight bends and secure it in the rack or patch panel to prevent strain on the connectors. Verify link status on connected equipment and run appropriate diagnostics if required.

Recommendations

Handle fiber connectors with care: always use proper cleaning tools and protective caps when connectors are not in use. Avoid bending the cable beyond the manufacturer’s minimum bend radius and limit exposure to mechanical stress. For critical or long-distance links consider matching fiber grading and connector types at both ends to maintain optimal signal performance.
