Fibre optic cable EFB Elektronik LC-ST 50/125µ 7.5 m

The EFB Elektronik LC-ST 50/125µ 7.5 m fibre optic cable provides a 7.5 metre duplex link built on OM4 multimode fibre with a 50 µm core. Terminated with an LC connector on one end and an ST connector on the other, this cable supports high-speed data transmission over short to medium distances and is compatible with networking equipment that accepts LC and ST interfaces. The construction is designed for stable optical performance and consistent signal transfer in structured cabling and point-to-point installations.

Advantages

This LC‑ST fibre optic cable uses OM4 50/125 µm multimode fibre to deliver enhanced bandwidth and reduced modal dispersion compared with lower OM classes, which helps maintain signal integrity at higher data rates. The combination of LC and ST connectors enables flexible connectivity between modern LC-equipped transceivers and legacy ST ports without adapters. The 7.5 m length provides a balance between reach and manageable cable routing in racks, cabinets, or cross-connects. The cable is assembled and terminated to industry connector types to support full-duplex communication.

Suitable for

• Connecting LC-equipped network switches or transceivers to ST ports on existing equipment
• High-speed data links in data centres, server rooms, and telecom closets
• Fiber backbone or horizontal cabling in office and enterprise networks
• Point-to-point links between network devices requiring multimode OM4 fibre

Key specifications

• Fibre type: OM4 multimode
• Core/cladding diameter: 50/125 µm
• Connector A: LC (ferrule optical connector)
• Connector B: ST (bayonet-style connector)
• Length: 7.5 m
• Mode: Multimode, full-duplex capable

How to use

Identify the LC and ST ports on the devices you intend to connect. Align and insert the LC connector into the LC receptacle until it clicks, then align and push the ST connector into the ST port and secure it with the bayonet twist if required. Route the cable to minimize sharp bends and avoid tight loops; maintain the manufacturer’s recommended minimum bend radius for multimode fibre to prevent attenuation or damage. Verify link integrity and transceiver settings after connection and test signal levels or link status using appropriate network diagnostics.

Recommendations

Handle the OM4 fibre with care: keep connector endfaces clean using appropriate fibre cleaning tools before connection, avoid excessive bending or tension on the cable, and store or route the cable in protected pathways. Use the cable for short to medium multimode runs consistent with OM4 performance guidelines and pair it with compatible transceivers and patch panels to ensure reliable operation.
