Text Box: Oval: Copper Cabling

Categories refer to individual components where classes refer to the overall link. Our compliance to standards ensures that the operating frequencies we offer are achieved and regularly exceeded. The table below summarises the various systems in their respective standards and their maximum operating frequencies. Now that Power Over Ethernet (PoE) is becoming more popular and is being developed to include more network peripherals the cabling choice is no longer just a bandwidth decision. The ability for Cat7A to deliver RF signals rather than a separate coax is just one example.
