Fibre optic cable EFB Elektronik O0347.0,5

The EFB Elektronik O0347.0 fibre optic cable is a 0.5 m OM4 patchcord designed for high-speed data transmission in structured cabling systems. It features an ST connector on one end and an SC connector on the other, with a 50 µm core diameter suitable for multimode applications in data centres and high-performance networks. The cable conforms to fibre jumper definitions in ISO/IEC 11801 and is intended as the short link between passive interfaces and active device ports.

Advantages

Reinforced with aramid yarn for improved tensile strength and long-term stability, the cable uses an LSZH halogen-free, flame-retardant sheath compliant with IEC-60754-2, IEC-60332-1 and IEC-61034. Connectors meet quality grades B/2 for singlemode and A/1 for multimode per IEC-61753 series (draft references). Each patchcord is 100% tested and supplied with an individual test protocol.

Suitable for

• Interconnects in data centres and server rooms
• High-performance multimode network links (OM4)
• Connections between active devices and passive panels or patch panels
• Short-range optical links requiring ST to SC termination

How to use

Install the EFB Elektronik O0347.0 patchcord by inserting the ST connector into the corresponding ST port and the SC connector into the corresponding SC port, ensuring correct alignment and secure latching. Route the cable along intended cable management paths, avoiding sharp bends and excessive tension to preserve the aramid reinforcement and optical performance. Follow standard fibre handling procedures: keep connector endfaces clean, use dust caps when not connected, and inspect or clean endfaces before mating.

Recommendations

For reliable performance, use this OM4 patchcord for short to medium multimode links inside racks or between panels. Store and deploy within manufacturer-recommended bend radius limits, avoid exposing the LSZH sheath to direct heat sources, and refer to the supplied individual test protocol for insertion loss data when certifying links.
