What does a two-way data transceiver (transverter) do?
A typical transceiver provides the wireless interface for cable modems at the subscriber’s site. It provides the corresponding inverse frequency conversion functions of the headend’s downstream transmitter and upstream receiver equipment. I.e. a transceiver includes a low noise downstream receiver and a frequency stable upstream transmitter. In fact, if the two data streams employ the same modulation and bandwidths, then the transceiver can be considered full duplex. Also, in point-to-point applications or for a small numbers of subscriber terminals, it is possible to use the same high power transceiver for headend and subscriber RF interfaces by simply switching the high/low ports of the transceiver’s antenna duplexer exclusively, for example, on the headend unit.
