Networking cable EFB Elektronik K5123.015 RJ-45 0.15 m Silver White

RJ45 plug to 2 x RJ45 jack — a compact 0.15 m networking cable that functions as a port doubler for structured cabling. The EFB Elektronik K5123.015 features an RJ-45 plug and two RJ-45 jacks in a silver and white design, suitable for short connections where splitting a single network port into two is required.

Advantages

The short 15 cm length keeps cable clutter to a minimum and is convenient for tight installation spaces. The plug-to-dual-jack configuration allows one Ethernet port to serve two devices without additional active hardware. The cable’s finish in silver and white provides a neutral appearance that fits into most office and home environments.

Suitable for

• Splitting a single RJ-45 network port into two for low-speed or temporary connections
• Short-distance connections in rack units, wall outlets or behind equipment
• Situations requiring compact cable routing to reduce clutter

How to use

Insert the RJ-45 plug into the source network port and connect up to two devices to the RJ-45 jacks. Ensure connectors are fully seated to maintain a reliable physical connection. This passive splitter is intended for short-range, low-complexity scenarios; it does not provide network switching or increase available bandwidth beyond the original port capacity.

Recommendations

Use this cable for temporary or low-bandwidth port-splitting tasks and in confined spaces. For permanent installs or where full independent network bandwidth and managed switching are required, use a proper network switch or structured cabling solution.
