LOGILINK RJ45 Coupler T-Adapter MP0137 — 2x 10/100Base-T RJ45 Couplers

The LOGILINK RJ45 Coupler T-Adapter MP0137 converts a single RJ45 connector into two 10/100Base-T RJ45 couplers, enabling simple passive splitting or extension of copper Ethernet cables. This compact passive accessory is designed for quick temporary connections, basic patching tasks and simple network expansions in home or small office environments without the need for tools or additional wiring.

Advantages

The T-adapter provides a tool-free way to duplicate or extend an existing Ethernet line while maintaining compatibility with standard 10/100Base-T equipment. Its compact, lightweight design allows easy placement behind furniture, inside patch panels or in temporary installation points. Because it is passive, it requires no power and is plug-and-play with typical Cat5/Cat5e patch cables.

Suitable for

• Temporary network splits where two devices must share one Ethernet outlet
• Quick patching when extending a LAN cable length without re-cabling
• Home networks, small offices, or test setups that use 10/100Base-T devices
• Situations where a short-term or non-critical connection is acceptable

When it may not be suitable

This passive T-adapter does not provide network switching, traffic management, or increased bandwidth; it simply duplicates the physical cable connection. It is not appropriate for permanent installations where full-duplex operation, gigabit speeds, or reliable simultaneous multi-device performance are required. For managed networks, heavy traffic, or Gigabit Ethernet needs, a proper network switch or a different active device should be used.

Key specifications

• Interface: 1 x RJ45 (female) input to 2 x RJ45 (female) outputs
• Supported standards: 10/100Base-T Ethernet
• Operation: Passive, no power required
• Cable compatibility: Standard Cat5/Cat5e patch cables
• Physical form factor: Compact T-adapter housing suitable for in-line use

How to use

Insert the upstream Ethernet cable into the single RJ45 inlet and connect the two downstream devices using standard RJ45 patch cables to the two output couplers. Ensure cables are fully seated to maintain contact. Because the adapter is passive, there is no configuration, power or drivers required. Use it for short, low-demand connections or temporary testing; avoid relying on it for performance-sensitive or permanent network segments.

What to consider before purchase

• Requires 10/100Base-T network equipment; does not support Gigabit (1000Base-T) speeds
• Passive splitting can limit simultaneous device communication and does not replace a network switch
• Not intended for permanent installations or environments requiring guaranteed bandwidth and full-duplex operation

Usage recommendations

Use the LOGILINK RJ45 Coupler T-Adapter for temporary extensions, short-term testing and basic patching in home or small office setups. For reliable multi-device connectivity or higher speeds, consider an active Ethernet switch or a properly rated cabling solution.
