Fibre optic cable EFB Elektronik O0348.20 — OM4 multimode, ST–ST, 20 m

EFB Elektronik O0348.20 is a 20 m OM4 multimode fibre optic cable with ST connectors on both ends. It uses 50 µm core multimode fibres designed to support high-bandwidth short- to medium-range links such as data center interconnects, InfiniBand and other high-throughput fiber-optic connections. The cable conforms to structured cabling principles for fibre jumpers and is built with an LSZH sheath and aramid reinforcement for mechanical stability and flame retardance.

Advantages

The OM4 multimode construction provides increased bandwidth and reduced modal dispersion compared with lower multimode grades. ST–ST connectors offer reliable bayonet-style coupling for legacy and industrial equipment. The cable features aramid yarn reinforcement for improved tensile resistance and long-term stability, and an LSZH (halogen-free, flame-retardant) sheath meeting IEC-60754-2, IEC-60332-1 and IEC-61034 requirements. Each patch cord is 100% tested and supplied with an individual test protocol.

Suitable for

• Data centre links and rack-to-rack connections
• InfiniBand and high-throughput short-range applications
• Network backbones and aggregation where OM4 performance is required
• Environments requiring halogen-free cabling and enhanced mechanical strength

How to use

Inspect connectors and cable for damage before installation. Route the fibre jumper between the device port and the passive interface following the shortest practical path to minimize bending and stress. Use appropriate cable management and bend-radius protection; avoid sharp bends and tensile loads beyond the aramid-reinforced design limits. Plug the ST connectors into compatible ST ports using the bayonet coupling until they lock, and verify link status and signal quality using appropriate testing equipment and the supplied individual test report.

Usage recommendations

For best performance, use this OM4 ST–ST patch cord for short- to medium-range high-bandwidth links in controlled environments such as data centres and equipment rooms, maintain bend radii greater than the manufacturer’s minimum, and consult the supplied test protocol to confirm connector loss values before deployment.
