LogiLink RJ45 Port Doubler T-Adapter, 1x RJ45 Female to 2x RJ45 Female, 10/100 BaseT, Black (MP0137)

In a small office where a single network wall port must serve both a desktop PC and a VoIP phone, the LogiLink RJ45 Port Doubler splits one 10/100 BaseT connection into two, eliminating the need for an additional switch or cable run. This passive T-adapter uses the unused wire pairs in a standard Cat5/5e/6 cable to carry a second Fast Ethernet link, making it a practical solution for retrofitting existing cabling.

Key specifications

• Connector A: 1x RJ45 female (input)
• Connector B: 2x RJ45 female (output)
• Network standard: 10/100 BaseT (Fast Ethernet)
• Max data transfer rate: 100 Mbps per connection
• Wiring: Utilizes 4 wires per connection over 8-wire cable
• Requires a second port doubler at the opposite end for full functionality
• Housing material: ABS plastic
• Colour: Black
• Compatibility: Cat5, Cat5e, Cat6 cables
• Installation: Plug and play, no configuration needed

Why choose it

This adapter is a cost-effective way to double the number of available network ports without running new cables or installing a switch. It is ideal for structured cabling environments where only one cable is available but two devices need connectivity. The compact T-adapter design fits easily into tight spaces, and the robust ABS housing ensures durability.

Ideal use cases

• Connecting two devices (e.g., PC and IP phone) to a single wall outlet
• Temporary network expansion in meeting rooms or classrooms
• Retrofitting existing Cat5/5e/6 installations for additional ports
• Reducing cable clutter in offices and home networks

Good to know

The LogiLink RJ45 Port Doubler is a passive device that requires no power supply. For optimal performance, use a second port doubler at the other end of the cable run. It supports unshielded twisted pair (UTP) cabling and is compatible with standard Ethernet equipment operating at 10/100 Mbps.
