Coaxial Cable
詳細規格及用途描述
WorldwideCables provides Coaxial cable differing from other shielded cable used for carrying lower frequency signals such as audio signals, in that the dimensions of the cable are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a radio frequency transmission line.Coaxial cable has an extremely broad bandwidth; it will transmit signals from zero frequency (direct cur- rent) up to many millions of hertz. Literally, hundreds of conversations (or messages) can be frequency multiplexed and transmitted simultaneously over a single coaxial cable, or a television program occupying about 3,500,000 Hz can be transmitted simultaneously with hundreds of phone conversations.
