These cables are used in the tertiary, but also in the secondary level of a network. They are characterized by large performa nce reserves and outstanding perform ance. They can be used to implement services such as Fast Ethernet.These cables are made using 24 gauge (AWG) copper wires with about three twists per inch enabling them to transmit data at 1000 Mbps (-1 Gigabit per second) with a frequency of 100 MHz They are suitable for 10BASE-T, 100BASE-TX . They support a higher signal - to - noise ratio, providing better reliability for current applications and higher data rates for future applications. The mechanical characteristics are perfectly suited for the application in tight cable channels and platforms due to their optimized construction.
