What this cable is and who it is for

This 125‑foot black Cat6 patch cable provides reliable Gigabit Ethernet connections with Power over Ethernet support. It is built for installers and IT teams who need a single long run between a switch or hub and a wall jack in offices, warehouses or conduit pathways.

Practical limits of the Cat6 standard

The cable is rated for 250 MHz bandwidth and carries 1, 2.5, 5 and 10 Gbps signals up to 160 ft, so the 125 ft length stays within that distance envelope. It uses 24 AWG stranded 100 % copper conductors and meets CMG fire‑rating requirements for general‑purpose indoor use.

Installation ease and common pitfalls

Snagless RJ45 connectors and molded strain‑relief boots protect the clips from catching or bending sharply during pulls through raceways. The gold‑plated contacts resist corrosion, but the PVC jacket is not rated for outdoor or plenum spaces, so verify the fire code before routing through air‑handling areas.

Questions about this item

Which length and colour option should I pick for a 125-foot black run?

This specific model is a 125 ft black Cat6 patch cable, so it matches that exact requirement.

What real-world speeds will I see from the 250 MHz Cat6 rating?

It supports Multi-Gigabit 1, 2.5, 5 and 10 Gbps links up to 160 ft, so the full 125 ft run can carry 10 Gbps.

How does the RJ45 interface and CMG rating limit where I can install it?

The gold-plated RJ45 connectors handle up to 100 W PoE, and the CMG fire rating allows general-purpose in-wall or conduit routing.
