Fibre optic cable EFB Elektronik O0348.1 1 m ST Purple

The EFB Elektronik O0348.1 is a 1 m OM4 fibre optic cable with ST connectors on both ends. With a 50 µm core diameter and OM4 multimode specification, this purple fibre jumper (patchcord) is designed to provide a short, reliable optical connection between a passive interface and an active device port in structured cabling environments that follow ISO/IEC 11801.

Advantages

The cable uses aramid yarn reinforcement for improved 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 quality grading for multimode applications (grade A/1 according to IEC-61753 series). Each unit is 100% tested and supplied with an individual test protocol.

Suitable for

• Short multimode links between switches, transceivers and patch panels
• Data centre trunking and rack-to-rack connections
• LAN and campus network fibre links requiring OM4 performance

How to use

Connect one ST connector to the device port or transceiver and the other ST connector to the passive interface or patch panel port. Ensure connectors are clean before mating to avoid signal loss. Route the cable without sharp bends and avoid tension beyond the specified limits; the aramid yarn reinforcement improves tensile resistance but standard cable handling practices should be followed. Use the supplied test protocol to verify insertion loss and continuity after installation.

Recommendations

Store and handle the cable in a clean environment. Clean connectors with appropriate fibre cleaning tools before each connection. For permanent or long-distance links, verify that OM4 multimode is suitable for the required transceiver types and link budget.
