Bill, Thank you for the post about Lucent's optical amplifier. It sloves the puzzles how they can achieve 80 channels. If their optical amp has 80nm BW, it is easy to jam 80 channels inside without great wavelegth locking technology. ( I thougt they use 50GHz spacing or even 25GHz) However, I have doubt how flat it can be. Are you in optical transport design business? CJ

bill, I'm very familiar with the electro-absorption type modulators that LU refered to in their PR. One thing they did not mention was at what bit rate the 1000 km result was demonstrated for or in what type of fiber. I'm very doubtful that these devices can accomplish the 1000 km claim at OC-48 or higher in non-dispersion shifted fiber. External modulators (which most use) will always have less chirp which is the parameter of interest related to this claim.
