www.serverracksandcable.com Click Here For Cat5e and Cat6 Cable and Information Cat 5e Cat 5e cable is the extension of Cat 5 with the same data rate 100 MHz. Most of the specifications of Cat 5 are improved in Cat 5e like PSELFEXT (Power Sum Equal Level Far End Cross Talk), Attenuation and NEXT (Near-End Cross Talk). Cat 5e may be used for 10Base-T, 100Base-T2, 100Base-T4, 1000Base-T and 100BaseTX Ethernet. Cat 6: Cat 6 cable has a bandwidth of 250 MHz and is backward compatible with the lower categories. It supports the same Ethernet standards as Cat 5e and quickly replacing Cat 5e. www.serverracksandcable.com Cat 3: Category 3 has unshielded twisted pair wiring with the maximum bit rate of 16 Mbps and 100 ohm impedance. Common uses are with voice (analog), 10Base-T, 100Base-T2 100Base-T4 Ethernet. Cat 4: The unshielded twisted pair wiring fall in category 4. Supports maximum of 20 MHz of transmission with 100 ohm impedance. Cat4 is never widely used and is not considered to be a standard. However common uses could be with 10Base-T, 100Base-T2 and 100Base-T4 Ethernet.
