Black Box 3ft GigaBase CAT5e 350-MHz Crossover Ethernet Cable (Blue)

Overview

The Black Box EVCRB81-0003 is a three foot GigaBase CAT5e crossover Ethernet cable designed to connect two network devices directly without the need for a hub or router. It supports Gigabit Ethernet speeds up to 1 Gbps and is tested to 350 MHz, providing reliable high-speed data transfer for setups like switch-to-switch, computer-to-computer, or server-to-server connections. Its compact length makes it ideal for tight spaces such as racks or desks where minimizing cable clutter is important.

Key features

• Crossover wiring allows direct device-to-device connections, simplifying network setups by bypassing intermediate devices.
• Tested to 350 MHz, offering performance beyond the standard CAT5e requirement to reduce signal loss from crosstalk and return loss.
• Solid 24 AWG conductors combined with 50 micron gold-plated contacts maintain strong conductivity and resist corrosion over time.
• Snagless boot design protects the latch during cable pulls and provides strain relief to prevent damage from tight bends or frequent moves.
• Durability rated for at least 750 insertion and extraction cycles, making it suitable for environments with frequent cable changes like labs and data centers.
