## Long description

EFB Elektronik O0321.7 is a 7.5 m multimode fibre optic cable designed for short-range high-speed links and equipment interconnects. The cable uses OM2 multimode fibre with a 50 µm core diameter, features an LC connector on one end and an ST connector on the other, and provides full duplex transmission. The orange jacket denotes multimode use and helps with quick visual identification in patch panels and cable trays.
Advantages
The cable provides reliable full duplex data transfer suitable for InfiniBand and other fibre applications that require bidirectional channels. OM2 multimode fibre enables cost-effective short-distance high-bandwidth links with stable attenuation characteristics. The combination of LC and ST connectors offers compatibility with common networking equipment and legacy devices, while the 7.5 m length covers typical rack-to-rack and equipment-to-equipment runs without excess slack.
Suitable for
InfiniBand interconnects and short-range cluster links
Server-to-switch and switch-to-switch connections within server rooms
Laboratory and test-bench fibre connections requiring mixed connector types
Patch panel and cable management where multimode identification is needed
Key specifications
Fibre type: OM2 multimode
Core diameter: 50 µm
Length: 7.5 m
Connectors: LC (one end) to ST (other end)
Transmission mode: full duplex
Jacket colour: orange (multimode identification)
How to use
Inspect connector endfaces for dust or damage before installation and, if necessary, clean with appropriate fibre cleaning tools. Plug the LC connector into the LC-compatible port and the ST connector into the ST-compatible port, ensuring each connector is fully seated and the latch or bayonet coupling is secure. Route the cable through cable management systems or trays to avoid tight bends and excessive tension; maintain manufacturer-recommended bend radius for OM2 multimode fibre. Verify link status and perform any required optical power or continuity tests to confirm correct installation.
Usage recommendations
Store and handle the cable in a dry, dust-free environment; avoid sharp bends and kinks. Use fibre-specific cleaning products on connector endfaces before mating, and periodically inspect connections in high-use environments. For optimal performance in short-range multimode networks, pair OM2 fibre with compatible transceivers and equipment designed for multimode operation.
