Category 8 Verification Testing

Future-proof your facilities to meet the high demands of tomorrow’s data centers with our performance Verification program with optical fiber testing.

Designers and installers are looking for next-generation materials that can meet the high throughput demands of your data centers. That’s why it’s so important to have your cable, channel and permanent links tested by a third party. You need to be sure that they can meet your end user’s expectations for performance. With this in mind, we’ve launched a performance verification program for Category 8 (CAT8) cable.

Previously, as specified in CAT8 standards, cable consists of four thermoplastic insulated twisted pairs and 22 – 24 American wire gauge (AWG) conductors, which employ an overall metallic shield and or individual pair of shields under an overall thermoplastic jacket. Due to required shielding, installers and contractors will now need to ensure prudent cable/connector shield termination and proper grounding/bonding measures in their local area networks (LANs).

The program, which is based on the latest published requirements for CAT8 in ANSI/TIA-568C.2-1 and IEC/ISO 11801 (IEC 61156-9 and -10) for Category 8.1 and 8.2 cable, channel and permanent links encompasses sophisticated electrical performance test requirements that ensure the integrity of high-speed signal transmission. It also includes a comprehensive follow-up and market surveillance program that helps ensure your supply chain remains compliant and that your products are protected against counterfeits.  

Please note that CAT8 cabling and components have been specified for transmission performance requirements up to 2 gigahertz (GHz) for IEEE 25GBASE-T/40GBASE-T applications with a maximum length of 30 meters. This next-generation cabling offers four times the bandwidth of standard Category 6A cabling and is fully backward compatible with Category 6A cabling, including RJ45 connectivity.


At UL, we have a rich history of tackling the problems of today to create the solutions of tomorrow. That’s why we’ve invested so many resources into this program — it truly solves a critical challenge that so many users are facing in a data-driven market. Our Category 8 Verification Testing provides a simple solution for end-users and LAN infrastructure and building designers to future-proof their facilities in order to meet the high throughput demands of your data centers. That’s how we help you overcome critical challenges and that’s how we help you secure what’s possible.
