Archive for the ‘Cat4’ Category


Saturday, November 14th, 2009

Category 4 is the performance level for voice and data transmission up to 20 MHz or 16 Mbps, such as 4-/16-Mbps UTP.

Both Category 3 and 4 are unsuitable for today’s high speed networking standards and will need to be replaced with Cat5 cable as a minimum if you intend to run 100baseT Ethernet.
