Networking cable EFB Elektronik K5124.015 — 0.15 m, RJ-45 to 2× RJ-45

EFB Elektronik K5124.015 is a short networking cable (0.15 m) with one RJ-45 plug on one end and two RJ-45 sockets on the other, designed as a T-adapter for cable sharing between two ISDN devices or network endpoints. The compact cable provides a simple passive connection that splits a single Ethernet line into two RJ-45 ports where a brief physical link is required.

Advantages

The K5124.015 offers a compact form factor and straightforward passive splitting without the need for additional power or configuration. Its short 0.15 m length minimises cable clutter and is convenient for close-proximity connections. Built with standard RJ-45 connectors, it is compatible with common Ethernet and ISDN cabling that uses RJ-45 terminations.

Suitable for

• Temporary cable sharing between two ISDN or Ethernet devices
• Short-distance connections inside cabinets or behind equipment
• Testing or troubleshooting network ports where a short splitter is useful

Key specifications

• Brand: EFB Elektronik
• Model / MPN: K5124.015
• EAN: 4049759022297
• Cable length: 0.15 m
• Connector 1: RJ-45 (plug)
• Connector 2: 2 x RJ-45 (sockets)

How to use

Connect the RJ-45 plug to the source network port and plug the two RJ-45 sockets into the device cables that need to share the line. Ensure connectors are fully seated. Because this is a passive T-adapter, it does not perform switching or signal regeneration; compatibility depends on the connected devices and the signalling they use.

Recommendations

Use this passive T-adapter only for short, low-bandwidth or testing scenarios. Do not expect full network switching, simultaneous full-speed connections, or protocol conversion. For permanent multi-device connections or managed traffic, use an appropriate network switch or splitter designed for the required signals.
