LogiLink RJ45 Connection Doubler, 1:1 Parallel T-Adapter, 1x RJ45 Female to 2x RJ45 Female, Black (MP0138)

Running out of network ports or need to share a single RJ45 line between two devices? The LogiLink MP0138 RJ45 Connection Doubler splits one RJ45 connection into two parallel ports, allowing two devices to connect to the same line without the need for an additional switch. This passive T-adapter is wired 1:1, making it ideal for telephone systems, legacy 10/100 Mbps Ethernet, or specific data applications where two endpoints must share a single physical connection.

Who is it for

This adapter is perfect for IT technicians, office administrators, and home users who need to temporarily or permanently split an RJ45 line for low-bandwidth applications. It is especially useful for connecting two telephones, older network devices, or non-simultaneous network access points where a full network switch would be overkill.

Main features

• 1:1 parallel wiring: Both output ports are wired identically to the input, providing a true parallel connection.
• Compact T-adapter design: Saves space and is easy to install in tight areas.
• Plug and play: No software or configuration required—simply connect your cables.
• Durable ABS housing: Protects internal connections from everyday wear and tear.
• Nickel-plated contacts: Ensure reliable signal transmission and corrosion resistance.
• Passive operation: No external power needed, reducing complexity and cost.

Tips

For best results, use this adapter only with 10/100 Mbps Ethernet or telephone lines. Avoid Gigabit Ethernet connections, as passive splitting may cause signal degradation. Both connected devices share the same physical line, so simultaneous high-bandwidth use is not recommended.
