Harmonic Deploys DWDM in Dallas9/06/1998 8:00 PM Eastern
Sunnyvale, Calif. -- Harmonic Lightwaves Inc. said its
dense-wave-division-multiplexing gear, branded "MetroLink," is now up and
running in Dallas.
Tele-Communications Inc. is the system operator for the
Harmonic deployment, but Harmonic couldn't cite the MSO's name in the release
because TCI is in a quiet period in anticipation of its acquisition by AT&T Corp.
However, a senior TCI source confirmed last week that it is
indeed using the Harmonic DWDM equipment not only in Dallas, but in its Olympia and
Vancouver, Wash., systems, as well as its Baton Rouge, La., system.
The Dallas DWDM installation is now servicing 13,000 homes
with video and high-speed-data services.
Earlier this year, TCI detailed aggressive plans to deploy
DWDM technology, naming Antec Corp. and Harmonic Lightwaves as key vendors in the
development of its DWDM plans.
Harmonic executives said the installation of the two-way
MetroLink system in Dallas took only three days to complete by equipping a single headend
that feeds two hubs, which, in turn, feed 54 optical nodes.
By using DWDM, digital information sent in the
1550-nanometer wavelength can be combined with analog video riding on the 1310-nm
John Trail, director of transmitter systems for Harmonic,
said more than 235,000 homes nationwide are currently passed by MetroLink-equipped
