Q15: What is the major UTP cable Categories?
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.
