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

The Black Box EVCRB81-0003 is a three foot GigaBase CAT5e crossover Ethernet cable that delivers high speed connectivity you can rely on when you need to link two network devices directly. It is ideal for switch to switch, computer to computer, or server to server connections where you want to bypass a hub or router and keep the setup simple.

Each cable undergoes testing up to 350 MHz, well above the 100 MHz minimum for CAT5e, and comfortably carries Gigabit Ethernet traffic up to 1 Gbps. That extra headroom guards against signal loss created by crosstalk and return loss, so large files, backups, and video streams move without interruption.

Black Box uses solid 24 AWG conductors capped with contacts that have 50 micron gold plating. These materials hold their conductivity and resist corrosion even after repeated use, and the plug is rated for at least 750 insertions and extractions, a benefit in labs, classrooms, and data centers where cables often see constant changes.

Each end features a boot with a snagless design that shields the latch while you pull the cable through a crowded rack or behind a desk. By also acting as strain relief, the boot helps the cable survive tight bends and routine moves.

With only three feet of length, the EVCRB81-0003 stretches between adjacent ports on a rack yet keeps excess slack out of the way. It is a practical choice for network engineers, IT technicians, and home lab enthusiasts who want a quick and tidy patch between devices without added clutter.

• Three foot crossover cable tested to 350 MHz and supports speeds up to 1 Gbps
• Crossover wiring enables direct device to device connections without a hub or switch
• 24 AWG conductors and contacts with 50 micron gold plating preserve signal quality
• Boot with a snagless design provides strain relief and prevents latch damage during pulls
• Rated for at least 750 insertion and extraction cycles, so it withstands frequent changes
