25 ft Cat8 Ethernet Cable

This 25-foot Cat8 patch cable delivers up to 40 Gigabit data transfer speeds and up to 2 GHz bandwidth using pure bare copper conductors. It is built for IT managers and data centre operators who need a future-proof, high-performance copper link. The double-shielded S/FTP construction helps protect signal integrity in dense networking environments. Snagless RJ45 boots guard the retaining clips during routine handling.

Double-Shielded S/FTP Installation

The snagless boot design prevents the RJ45 retaining clip from catching on adjacent cables or panel openings during insertion and removal. Double shielding (S/FTP) adds stiffness compared to unshielded patch cords, so allow a gentle bend radius rather than forcing tight corners. The 28 AWG conductors are thinner than typical Cat6 wires, making the cable more flexible but also easier to kink if pulled sharply. Ensure the plug clicks fully into the jack to guarantee all eight contacts mate correctly.

Pre-Installation Compatibility Check

Verify that both endpoints support Cat8 performance or at least the speed tier you intend to run, as the cable will negotiate down to the lowest common standard. Confirm the 25-foot length fits your rack or patch-panel layout without excessive slack that could block airflow. Check that your switch ports and server NICs use standard RJ45 sockets compatible with the snagless boot profile. The pure bare copper construction meets UL 444 and TIA-568-C.2 fire and safety codes for in-wall or plenum-adjacent runs where regulations permit.

Questions about this item

How can I confirm the cable is delivering 40Gbps after connecting it?

Verify the link speed in your OS network adapter settings or switch management interface; a negotiated 40Gbps connection confirms the 2GHz bandwidth and Cat8 rating are active.

What comes with the Monoprice 145421 and what must I provide?

The 25 ft blue Cat8 patch cable with two snagless RJ45 plugs is included; you supply the router, switch, server or NIC ports to plug each end into.

Which length should I choose for a 25-foot run between rack and switch?

Select the 25 ft version — it matches the exact distance and keeps the channel within Cat8 limits without excess slack.
