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.
