## Long description

The EFB Elektronik LC‑ST 50/125µ InfiniBand 3 m fibre optic cable is a 3‑metre duplex patch cable designed for high‑performance network links. It uses OM4 multimode fibre with a 50 µm core diameter and terminated with LC and ST connectors to provide reliable, low‑loss optical connections for InfiniBand and other high‑speed communication systems. The cable supports full duplex data transmission and is intended for short‑to‑medium range metropolitan, data centre and enterprise environments where low latency and high bandwidth are required.
Advantages
The OM4 multimode fibre construction offers improved bandwidth and lower modal dispersion compared with lower OM grades, enabling higher data rates over the specified distances. The combination of LC and ST connectors allows compatibility with a wide range of transceivers and legacy equipment, while the duplex configuration supports simultaneous transmit and receive channels. The 3 m length provides a balance between flexibility and signal integrity for rack‑to‑rack and equipment interconnects.
Suitable for
 InfiniBand high‑performance computing interconnects
 Data centre server and switch connections
 Storage area network (SAN) links
 Telecommunication equipment and lab test setups
Key specifications
 Fibre type: OM4 multimode
 Core/cladding diameter: 50/125 µm
 Connector A: LC
 Connector B: ST
 Length: 3 m
 Configuration: Duplex, full duplex optical link
How to use
Inspect connectors and ports for dust or debris before connecting; clean with appropriate fibre cleaning tools if necessary. Align the LC connector with the LC port and insert until it clicks, then align and insert the ST connector by engaging its bayonet coupling. Ensure the cable is routed without tight bends; maintain the manufacturer’s minimum bend radius to avoid increased attenuation. Verify link status and data throughput after connection using network management tools or device indicators.
Usage recommendations
Store and handle the cable in a dry environment and avoid sharp bends or crush loads. Use dust caps when connectors are not in use, and perform regular visual inspections and cleaning to preserve signal quality and prolong service life.
