Cable & Wire | Good quality and good service based on reasonable prices.
Cat 6 (Category 6) is a cable standard used mainly for Ethernet computer networking, security systems, and telephone services. Cat 6 cable is backward compatible with the Cat 5E, Category 6 cable is capable of transmitting voice and data up to 155 Mbps (mega bits per second), with possible transmission frequencies up to 550 MHz.
Cat 6 carries Ethernet 10Base-T, 100Base-TX, and 1000Base-T (Gigabit Ethernet) connections. Cat 6 cable is backed with more stringent specifications for crosstalk and system noise than earlier cabling standards.<o:p>
Category 6 cables come with four twisted copper wire pairs and each twisted pair is built of larger 23 gauge copper. The earlier model, Category 5, used 24 gauge copper wires. In wire gauges, a larger number indicates a smaller wire.
Cat 6 cables are generally terminated with RJ-45 electrical connectors. The signal path’s performance will be limited to that of the lowest category if components of the various cable standards are intermixed. The maximum length of one Cat 6 cable segment is 220 meters. A repeater needs to be installed to send data over longer distances or data loss may occur.
