Mark, here is another company using HLIT's MetroLink DWDM system,and look at the answer they gave,WOW! CMCSK is in our fold,and loves us,Paul Allen at Charter is gonna be a big buyer. Tuesday February 16, 8:43 am Eastern Time Company Press Release Comcast Deploys Harmonic Lightwaves' METROLink DWDM System in Digital Upgrade METROLink Allows Sarasota, Fla. System to Provide Digital Services SUNNYVALE, Calif.--(BUSINESS WIRE)--Feb. 16, 1999--Harmonic Lightwaves, Inc. (Nasdaq:HLIT - news) today announced that its METROLink(TM) Dense Wave Division Multiplexing (DWDM) system is being deployed by Comcast Corp. in its Sarasota, Fla. system as part of an upgrade. In this system, METROLink is being used to upgrade the return path from the hubs to the headends. METROLink will greatly increase the system's return-path capacity by transmitting eight wavelengths over a single fiber. ''In investigating our options for upgrading the return-path portion of this system, we quickly identified DWDM as offering the best mix of performance and price,'' said Andrew Behn, the area engineering manager for Comcast's West Florida cluster. ''After a comparative evaluation, we chose Harmonic's METROLink as our DWDM solution.'' ''This latest deployment of METROLink shows the growing acceptance of DWDM by cable operators,'' said Colin Boyd, Harmonic's vice president of North American sales and worldwide marketing. ''Even for operators who have already upgraded the forward-path portion of their systems, DWDM is a very attractive and cost-effective solution for providing a robust return-path, which is vital for the delivery of two-way services.'' In addition to this deployment by Comcast, METROLink systems are also being used by Tele-Communications, Inc. (TCI) in many of its systems throughout the nation. About METROLink Harmonic's METROLink system uses DWDM to substantially increase the downstream and upstream bandwidth capacity of hybrid fiber/coax (HFC) networks for the delivery of services that require two-way communication, such as telephony, Internet access and video-on-demand. Additionally, METROLink allows operators to provide narrowcast services directly from the headend, thereby eliminating the need to put costly and complex equipment in hubs. In the METROLink system, each narrowcast wavelength carries several channels of digital subscriber service. The multiple narrowcast wavelengths are transported on a single fiber from the headend to the hub where they are unbundled and individually optically combined with the broadcast signal. The combined two wavelengths of broadcast and narrowcast signals are then sent out to a targeted single node or group of nodes. A similar DWDM arrangement is used to bring the return signal back to the headend. The two-way METROLink system is composed of Harmonic's proven 1550 nm transmitters on the International Telecommunications Union (ITU) grid, gain-flattened optical amplifiers and matching passive components.
