The purple jacket aids identification; suitable for data centres, server racks and short-range links.

## Long description

Fibre optic patch cable EFB Elektronik O0348.7 is a 7.5 m multimode OM4 ST–ST patchcord designed for short-range, high-speed fibre links. The cable uses 50 µm core diameter multimode fiber to support increased bandwidth and reduced attenuation. Its purple LSZH jacket provides easy identification and halogen-free, flame-retardant protection for use in data centres and server racks. Connectors on both ends are ST type, and each cable is 100% tested and delivered with an individual test report.
Advantages
The OM4 multimode fiber enables higher bandwidth for short-reach applications and improved performance compared with lower-grade multimode fibers. The cable core is reinforced with aramid yarn for better tensile strength and long-term stability. The LSZH (halogen-free, flame-retardant) sheath conforms to IEC-60754-2, IEC-60332-1 and IEC-61034 standards. Connectors meet IEC-61753 quality grades B/2 for singlemode references and A/1 for multimode, and each patch cord is factory-tested with an individual test protocol.
Suitable for
 Data centre trunking and rack-to-rack connections
 Server farm and switch-to-switch short-range links
 High-speed InfiniBand and fibre-optic network segments
 Patch panels and active device ports requiring ST–ST terminations

How to use
Route the OM4 ST–ST patch cable between the device port and the passive interface or patch panel, avoiding sharp bends and mechanical strain. Ensure ST connectors are properly aligned and inserted into ST sockets with a quarter-turn bayonet engagement. Keep bend radius within manufacturer recommendations and secure excess cable to prevent stress on connectors. Use the individual test report to verify insertion loss and return loss values before putting the link into production.
Usage recommendations
For reliable short-range performance, install this OM4 ST–ST patchcord in controlled environments such as data centres and server rooms, maintain bend radii, and handle connectors by the ferrule housing to avoid contamination. Store and clean connectors according to standard fiber-optic maintenance procedures.
