Hi javeed_ccna,

A transmission facility having a bandwidth sufficient to carry multiple voice, video or data channels simultaneously. Each channel occupies (is modulated to) a different frequency bandwidth on the transmission medium and is demodulated to its original frequency at the receiving end. Channels are separated by ìguardbandsî (empty spaces) to ensure that each channel wonít interfere with its neighboring channels. This technique is used to provide 50 CATV channels on one coaxial cable.

IN short:
High-capacity high-speed, transmission channel carried on coaxial or fiber-optic cables with a wider bandwidth than conventional copper telephone lines.
