Network cable for fixed runs

The Black Box EVNSL640-0050 is a Category 6 patch cable built for permanent or semi-permanent links between switches, patch panels and wall outlets. Its 50 ft length suits rack-to-rack or floor-to-floor runs in offices and home labs. Solid conductors keep attenuation low over the full distance.

Steady throughput at 400 MHz

The solid-core construction maintains consistent insertion loss and return loss when the link runs continuously at the rated 400 MHz bandwidth. Unlike stranded patch cords, it does not degrade when left in place for months, making it reliable for PoE cameras, access points and desktop drops that stay active 24/7.

Low heat and silent operation

With no active components the cable generates no heat and adds no audible noise to the installation. The unshielded twisted-pair jacket draws zero power, so it has no impact on switch power budgets or rack thermal planning. Gray jacket blends into standard cable management.

Questions about this item

Will the 50 ft length cause noticeable heat or signal loss on a 400 MHz Cat 6 run?

At 50 ft the run is well within the channel limit for Cat 6, so attenuation stays negligible even with continuous PoE load.

What connectors must my switch and device already have for this EVNSL640-0050 to plug in?

Both ends are RJ-45 male, so the switch and the device each need a standard RJ-45 female port.

Can this Cat 6 patch cable work alongside older Cat 5e cabling already in the wall?

Yes, the Cat 6 cable is backward compatible with Cat 5e infrastructure and will negotiate the highest common speed.
