Fibre optic cable EFB Elektronik LC-ST 50/125µ InfiniBand 0.5 m

The EFB Elektronik LC-ST 50/125µ fibre optic cable, 0.5 m, OM4, is designed for short interconnects in high-speed networks. It uses a 50 µm multimode core and supports full duplex data transmission, with LC and ST connector types on each end to interface equipment that requires these common connector formats. The compact 0.5 m length is suitable for patching between nearby devices in racks, switches, or InfiniBand-based systems where controlled link distance and signal integrity are required.

Advantages

The OM4 multimode fibre offers improved modal bandwidth and lower attenuation for short-range high-bandwidth links. Using LC on one end and ST on the other provides compatibility between devices with different connector types without additional adapters. The 50 µm core size is standard for multimode networking and supports InfiniBand applications, enabling reliable full duplex communication. The short 0.5 m length reduces excess cable slack in dense cabling environments and helps maintain tidy rack layouts.

Suitable for

• InfiniBand interconnects and short-range high-speed links
• Patch connections inside server racks and data closets
• Interfacing equipment with LC and ST fibre connectors
• Short multimode fibre links requiring OM4 performance

Key specifications

• Fibre type: OM4 multimode
• Core/cladding diameter: 50/125 µm
• Length: 0.5 m
• Connector A: LC
• Connector B: ST
• Transmission mode: Full duplex

How to use

Inspect connector endfaces for contamination before insertion and clean if necessary with appropriate fibre cleaning tools. Align and insert the LC connector into the corresponding LC receptacle and the ST connector into the ST port until it seats securely; the ST connector typically requires a twist-and-lock action. Route the cable to avoid tight bends and mechanical strain, keeping bend radius within the fibre manufacturer’s recommendations. Verify link status and signal integrity using optical testing or the host devices’ diagnostics after installation.

Usage recommendations

For reliable operation, store and handle the cable in a clean environment, avoid sharp bends, and use a dust cap on unused connectors. Choose the 0.5 m length for close-proximity patching to minimize excess slack; for longer runs select an appropriately rated multimode cable.
