As I said, let the games begin- Sure, folklore and cultural affinities play a role, and so does history. I remember when the hype was ISDN--I use ISDN, and it is great. How long did it take and were telcos sluggish ?? You bet. Todays hype is DSL--Tomorrows is ?? Let the games begin. cable, DSL wireless and more.

Scientific-Atlanta Announces Scaleable Fiber Optic Solution To Enable Up To 16 Times More Capacity For New Services -- New Prisma DWDM Transport System will enable cable operators to December 4, 1998 ANAHEIM, Calif., Dec. 3 /PRNewswire/ via NewsEdge Corporation -- At the Western Cable Show today, Scientific-Atlanta, Inc. announced a new network technology that will allow operators to incrementally upgrade their capacity by as much as 16 times over a single fiber optic cable, which will enable them to offer more revenue- generating interactive services at a much lower cost than with traditional network architectures. The Prisma(TM) Dense Wave Division Multiplexing (DWDM) transport system reduces the cost of deploying new services because the interactive technology is retained at the network's headend, instead of at numerous hub locations. This lowers equipment and maintenance costs, while still enabling the ability to target programming and services for a wide area from a single location. The Prisma DWDM Transport System is currently available for shipment. "Scientific-Atlanta's new Prisma DWDM Transport System enables cable operators to match investments with new revenue opportunities from video, data and voice services," said John Clark, vice president of Scientific-Atlanta's Optoelectronics business unit. "The system also gives operators simpler, more cost-effective control over targeted programming, while increasing transmission speeds to much larger areas over a single fiber. " Technical Features The Prisma DWDM Transport System is a scaleable solution that can deliver additional downstream network capacity in increments of four targeted data streams -- each serving about 8,000 homes -- up to 16 unique data streams on a single fiber optic cable through the use of ITU gridded 1550 nm externally modulated transmitters. This allows the cable operator to cost-effectively increase capacity as needed to accommodate a wide variety of two-way interactive services and additional channels. For upstream data traffic from the hub to the headend, Scientific- Atlanta's new Prisma DWDM Transport System provides the capability for scaleable reverse path transmission through the use of a family of directly modulated ITU gridded 1550 nm transmitters. Up to 16 unique data streams -- typically serving four optic nodes each -- may be combined onto a single fiber. Scientific-Atlanta's Prisma Optical Networks family is a full line of optoelectronics products, including 1550 nanometer externally modulated electro-optic transmitters and erbium-doped and erbium/ytterbium-doped fiber amplifiers; 1310 nm fiber optic transmitters and fiber optic nodes; and the Prisma Dense Wave Division Multiplexing Transport System.

Thread, Recently I've heard some personal accounts, and I have received some emails to the same effect, stating that the reliability of DWDM devices [of all current manufactures] is less than stellar. Horrible, is the way one source explained it. Too many moving parts and breadboard-like architectures are the blame, resulting from a rush to get product out the door. The only thing lacking on some devices is an exhaust pipe, one guy told me. Kludgeville. This has caused me to want to take a closer look, which I intend to do during the next couple of weeks. To offset these problems during the early stages of deployment, it's been suggested to me that roughly one half of all lambda availability through dwdm gain, is reserved for backup of other lambdas within the same and adjacent systems. This, because individual wavelength provisions tend to individually fail, as opposed to the entire box. This measure of backing up other lambdas is a safeguard in addition to the self-healing capabilities of the Sonet rings that these lambdas support, I've inferred. Anyone else hear of similar stories from the field? Curious.
