## Summary description

The EFB Elektronik LC-ST fibre optic cable is a 1 m long OM4 type cable with a core diameter of 50 µm. It features LC and ST connectors, ensuring full duplex communication. Ideal for high-speed data transmission, this cable is designed for reliable performance in InfiniBand applications.

## Long description

The EFB Elektronik LC‑ST 50/125µ OM4 fibre optic cable is a 1 m duplex patch cable designed for high‑speed data links and short‑reach multimode applications. With a 50 µm core diameter and OM4 grading, the cable supports increased bandwidth and improved modal performance compared with lower OM classes. The cable terminates with an LC connector on one end and an ST connector on the other, enabling compatibility between devices and transceivers that use these connector types in InfiniBand and Ethernet networks.
Advantages
This OM4 multimode cable provides higher bandwidth and lower attenuation for short to medium distances, which helps maintain signal integrity in dense server, switch and storage environments. The LC connector offers a compact form factor for high‑density ports while the ST connector provides a bayonet style connection commonly used on legacy equipment. Duplex construction supports simultaneous transmit and receive channels for full‑duplex data transfer required by InfiniBand systems. The 1 m length reduces excess slack in patching scenarios and simplifies cable management in racks and cabinets.
Suitable for
Short‑reach multimode fibre links in data centre racks and server rooms
InfiniBand interconnects between switches, host channel adapters and storage arrays
Connections between LC‑terminated transceivers and ST‑terminated panels or devices
High‑density patch panels and equipment requiring duplex multimode cabling
Key specifications
Fibre type: Multimode OM4
Core diameter: 50 µm
Cladding diameter: 125 µm
Connector A: LC (single duplex connector)
Connector B: ST (bayonet duplex)
Length: 1 m
Transmission mode: Duplex, full‑duplex capable
Typical use: Short‑reach high‑speed links (InfiniBand, Ethernet)
How to use
Inspect connectors and cable for visible damage before installation. Align the LC connector with the LC duplex port and press until it clicks, ensuring correct orientation. Insert the ST connector into the ST receptacle and rotate to engage the bayonet locking mechanism. Use gentle handling and avoid tight bends; maintain the recommended minimum bend radius for multimode fibre to prevent increased attenuation. Route the 1 m cable through the intended patching path, secure with appropriate cable ties or Velcro straps, and avoid compressing the cable when closing patch panels or cable management hardware.
Usage recommendations
For optimal performance, keep endfaces clean using proper fibre cleaning tools before mating connectors, and verify link performance after installation. Use this OM4 50/125µ cable for short‑reach, high‑throughput applications; for longer runs consider singlemode or higher‑graded multimode solutions. Store and handle the cable to avoid kinks and excessive tension.
