Thanks. We'll let you know when a new response is added.

A15:Category 1 & Category 1 ( 1Mhz ) is mainly used for Analog voice (plain old telephone service), ISDN Basic Rate Interface Doorbell wiring.
Category 2 – Category 2 (4 Mhz) is mainly used in the IBM Token Ring networks
Category 3 – Category 3 (16Mhz) is mainly used for 10Base-T, 100Base-T4, and 100Base-T2 application.
Category 4 – Category 4 (20Mhz) is mainly used for 10Base-T, 100Base-T4, and 100Base-T2 application.
Category 5 – Category 5 (100Mhz) is mainly used for 10Base-T, 100Base-T4, 100Base-T2, and 100Base-TX application.
Category 5e – Category 5e (100Mhz) is mainly used for 10Base-T, 100Base-T4, 100Base-T2, and 100Base-TX and 1000Base T2 application As compared to Cat 5 cable, it has improved specifications for NEXT and PSELFEXT and Attenuation.
Category 6 – Category 6 (250Mhz) is mainly used for 1000Base T2 application.
As compared to Cat 5e cable, it has improved specifications for NEXT and PSELFEXT and Attenuation.
Category 7 – Category 7 is a proposed standard that aims to support transmission at frequencies up to 600 MHz over 100 ohm twisted pair.wyatt is gai.

    STP cables are known are Sheilded Twisted Pair cables, STP cabling includes metal shielding over each individual pair of copper wires. This type of shielding protects cable from external EMI (electromagnetic interferences). e.g. the 150 ohm shielded twisted pair cables defined by the IBM Cabling System specifications and used with token ring networks. STP cables are CAT 5, CAT 5E and CAT 6
