Black Box EVCRB83-0020

Overview

The Black Box EVCRB83-0020 is a 20-foot CAT5e crossover patch cable designed to connect two network devices directly without needing an uplink port or adapter. It supports data rates up to 1 Gbps and operates at a bandwidth of 350 MHz, making it suitable for Fast Ethernet and Gigabit Ethernet applications. The cable’s red jacket ensures easy identification in complex setups, while its flexible construction allows smooth routing behind desks, through wall plates, or within patch panels.

Key features

• 350 MHz bandwidth offers performance headroom to reduce signal loss and interference
• Crossover wiring enables direct device-to-device connections, ideal when auto-MDI-X is not available
• Stranded 24 AWG conductor core provides flexibility for frequent moves and tight bends without compromising durability
• 50-micron gold-plated contacts resist corrosion and maintain consistent electrical connections over thousands of insertions
• Molded, snagless boots protect the latch from damage during cable pulls and rerouting
• Exceeds CAT5e standards to ensure reliable and high-quality data transmission
• Bright red jacket makes the cable easy to spot in crowded racks or network environments

Connectivity and compatibility

This crossover cable is designed for direct connections between computers, switches, or other network devices without requiring an uplink port. It works well in environments where auto-MDI-X is not supported, such as certain switch-to-switch links or test-bench setups. The cable’s CAT5e rating ensures compatibility with Fast Ethernet and Gigabit Ethernet networks, making it a versatile choice for small offices, labs, or home networks.

Durability and handling

The stranded conductor core keeps the cable flexible enough to handle frequent repositioning and tight bends, which is common in dynamic network environments. The molded, snagless boots protect the RJ45 latch from accidental damage during installation or maintenance, extending the cable’s lifespan. Its rugged design supports everyday use while maintaining signal integrity.

Ideal uses and environments

This cable fits well in setups requiring direct device-to-device connections without additional adapters, such as peer-to-peer computer links or switch interconnections in environments lacking auto-MDI-X support. Its length and visibility make it practical for wiring between racks and workstations in small offices, labs, or home networks where reliable Gigabit Ethernet performance is needed.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
