Crossover Modular Adapter Goobay RJ45 CAT 5e

The Crossover Modular Adapter Goobay RJ45 CAT 5e is a compact red adapter designed for CAT 5e Ethernet networks. It provides two RJ45 connectors configured for crossover wiring, enabling direct device-to-device connections without a hub or switch. The adapter's small form factor and sturdy housing make it suitable for temporary or permanent linking of compatible network devices where a crossover connection is required.

Advantages

The adapter offers straightforward connectivity between two Ethernet devices by internally swapping transmit and receive pairs according to crossover wiring patterns. Its CAT 5e-rated contacts support standard 100 Mbps Fast Ethernet and are compatible with many modern devices that require crossover connections. The robust, molded housing protects the connectors while the bright red color makes the adapter easy to identify among cables and ports.

Suitable for

• Direct connection between two computers or laptops without a switch
• Linking two network devices such as routers, hubs, or switches for diagnostics or temporary setups
• Creating a temporary crossover link in field or lab environments

Key specifications

• Cable standard compatibility: CAT 5e
• Connector type: two RJ45 female ports (crossover wiring)
• Data rates supported: up to standard Fast Ethernet (100 Mbps) over CAT 5e cabling
• Housing: molded, compact design for portability
• Color: red for easy identification

How to use

Insert an RJ45 cable from the first device into one side of the adapter and a second RJ45 cable from the other device into the opposite side. Ensure connectors are fully seated to engage contacts. Once connected, devices configured to negotiate link speed will establish a crossover connection without additional configuration on devices that support auto MDI/MDIX. For devices that do not support auto-negotiation, confirm network settings and link speed manually.

Usage recommendations

Use the adapter with properly terminated CAT 5e cables and avoid excessive bending near the connectors. For permanent installations or higher-speed requirements, consider using properly wired patch panels or switches supporting the required link speed.
