Belkin CAT5e 3ft Crossover Ethernet Cable (Blue)

Overview

The Belkin A3X126-03-BLU is a 3 ft CAT5e crossover Ethernet cable designed to connect two network devices of the same type directly, such as computers or switches, without needing a router or uplink port. It supports data transfer speeds up to 1 Gbps, making it suitable for fast file sharing, resource sharing, or network troubleshooting in small setups. The cable’s bright blue PVC jacket and flexible stranded copper wiring ensure durability and easy identification in busy environments.

Key features

• Crossed wiring scheme reverses transmit and receive pairs for direct device-to-device connections without intermediate hardware
• Flexible stranded copper conductors maintain signal integrity while allowing easy cable management
• Durable PVC jacket in blue protects the cable and helps quickly locate it among other cables
• RJ45 connectors with 50 micron gold plated contacts resist corrosion and ensure reliable electrical contact
• Molded strain relief at connectors reduces stress from bending and frequent unplugging, extending cable life
• Automatically negotiates 10BASE-T, 100BASE-T, and 1000BASE-T speeds for compatibility with a wide range of network equipment
