To all, TCI upgrade Dallas to 2-way HFC in just 3 days!! Wow, what an accomplishment,one headend servicing 54 nodes! HLIT is going to pull TCOMA's fat ass out of the fire. Tuesday September 1, 8:33 am Eastern Time Company Press Release Harmonic Lightwaves Announces Deployment of Cable Television's First Fully Operational DWDM System Major MSO's Dallas Network is Equipped With Harmonic's METROLink DWDM System SUNNYVALE, Calif.--(BUSINESS WIRE)--Sept. 1, 1998--Marking the cable television industry's first deployment of a fully operational eight wavelength, forward and return-path Dense Wave Division Multiplexing (DWDM) system, Harmonic Lightwaves, Inc. (Nasdaq:HLIT - news) today announced that the company's METROLink(TM) DWDM system is being used by a major MSO to provide 13,000 homes in the Dallas area with video services and high-speed Internet access. Installation of the two-way METROLink system required only three days to complete, with an engineering team from Harmonic working closely with local system engineers. The upgraded hybrid fiber/coax (HFC) network consists of a single headend feeding two hubs which in turn feed 54 optical nodes that pass 13,000 homes. With METROLink, the system is now fully-two way, enabling the operator to offer high-speed Internet access via cable modem. In addition to this installation, five hybrid METROLink systems have also been deployed in the operator's Dallas-area network. In these hybrid installations, one or both of the networks' paths are coarse WDM, with digital information being transmitted at 1550 nm and combined with analog video at 1310 nm. Currently 135,200 homes in the Dallas metro area are passed by METROLink-enabled systems. ''As the industry's first commercially deployed true DWDM system, this METROLink installation is a milestone for Harmonic and the cable television industry,'' said John Trail, Harmonic's director of transmitter systems. ''The straightforward deployment of this full eight wavelength, forward and return system demonstrates the high quality and plug-and-play nature of the METROLink product line. ''The speed with which the system was installed illustrates how METROLink can enable the rapid upgrade of HFC networks for delivery of two-way services.'' A variety of coarse and dense WDM METROLink systems have also been deployed by the operator in its Baton Rouge, La.; Olympia, Wash. and Vancouver, Wash. systems. Currently over 235,000 homes nationwide are passed by METROLink equipped networks. Hiram
