| Baseband Coaxial Cable |
| Baseband coaxial cable transmits
a single digital signal in half-duplex mode only. No frequency modulation
takes place as in broadband transmission, but the raw bit stream is equally
specially modified before transmission, using techniques such as Manchester
encoding. The absolute maximum data rate supported is 50 Mbps, since it
may occupy the full available cable bandwidth if 50 MHz; However, typical
practical maximum range from 3Mbps to 10 Mbps. Baseband cable is generally used only with linear bus topologies. A typical network with this medium contains 200 to 1000 devices. |
