Black Box 20ft GigaBase CAT5e Crossover Ethernet Patch Cable (Green)

The Black Box EVCRB82-0020 is a patch cable that offers GigaBase CAT5e performance, uses a crossover pinout, and measures 20 feet in length. It creates a direct Fast Ethernet link between two network devices such as switches or computers. Because it arrives pre-wired, you can plug it in and start transferring data immediately without extra adapters or reconfiguration.

Every GigaBase cable is tested up to 350 MHz, far above the 100 MHz baseline defined for CAT5e. This generous margin reduces impedance, return loss, and near end crosstalk for fewer errors and steadier throughput during bandwidth-intensive tasks such as large file backups or high-quality media streaming.

The cable's green jacket houses four twisted pairs made from flexible 24 AWG stranded copper. Each RJ45 plug includes 50-micron gold-plated contacts that maintain a clean electrical path, and a snagless boot that shields the latch when you thread the cable through crowded wiring channels. The result is a patch lead that withstands repeated connect-disconnect cycles and tight bends without performance loss.

IT professionals, small office managers, and home users alike will find this cable handy for quick peer-to-peer file transfers, lab environments, backup links between switches, or any situation where a reliable crossover connection is required.

• Tested to 350 MHz, offering headroom beyond the CAT5e standard
• Twenty-foot length spans typical rack, desk, or room distances
• Crossover wiring enables direct switch-to-switch or computer-to-computer links
• 50-micron gold-plated contacts resist corrosion and keep signals clean
• Snagless boots protect the RJ45 latch and ease installation
• Four twisted pairs of 24 AWG stranded conductors add flexibility and long service life
