Our 24AWG FTP Tight Twist CAT3 riser cable offers enhanced crosstalk and attenuation over traditional DS1 cable products. It is mainly used as digital transmission cable for DS1/T1, DS1C and DS2 frequencies in switching and transmission equipment. This design provides true TI A Category3 electrical performance for applications where T1 speeds and low-loss shielded cable is required.
