Cable companies have been saying for years that they don't have the bandwidth needed to carry new HDTV channels and subchannels without trimming back their current channels. That's been, IMO, one of the major roadblocks hindering HDTV expansion.

The restriction for hybrid fiber optic and coaxial cable systems has largely been the coaxial-cable amplifiers, which typically limit systems to about 750 MHz bandwidth. The optical-fiber portion of cable systems, though, can be vastly expanded by simply multiplexing additional light wavelengths.

But now, according to this article and company press release , newly developed coaxial-cable amplifiers employing silicon-germanium technology can handle frequencies up to 2 GHz, doubling bandwidth. According to the company, network tests are slated for early 2002. -- John
