Description:
Category 3 cable, or CAT3 cable is a type of twisted pair cable frequently used in voice and data applications. Phone cable is defined by the Electronic Industry Alliance (EIA) and Telecommunication Industry Association (TIA). HUIER Cable's CAT3 phone cable is quality manufactured to meet and/or exceed product certifications and standards for EIA/TIA 568 and ISO/IEC 11801 specifications.
Application:
Category 3 is suitable for high speed DATA/LAN transmission up to 16 Mbps.
10 Base-T
4 Mbps Token Ring
Voice
Cat3 cable is still in use as a Voice grade cable, primarily for POTS (Plain Old Telephone Service) and though some data can be sent through it (Think DSL) the rate is limited to about 10 Mbps and is subject to more errors than modern grades of LAN cable. Even for Telephone service, if you are replacing or Installing lines in your house, you can't go wrong investigating the use of Cat5e or Cat6 cables as future uses and extra lines are built in.
