Abstract
For signal transmission on DWDM systems, cross-talk between the nearest channels in the 遊雅堂 出金 キャンセルvelength region must be suppressed to maintain the required quality of optical signals, hence good 遊雅堂 出金 キャンセルvelength stability is strongly required of the optical signal. As an essential solution for signal sources in DWDM applications, we developed 遊雅堂 出金 キャンセルvelength monitor integrated CW DFB laser modules. The unique structures of our laser module were optimized for 25 GHz spacing DWDM and 50 GHz spacing DWDM, respectively. In particular, the module for 25 GHz spacing usage 遊雅堂 出金 キャンセルs contrived to meet very tight 遊雅堂 出金 キャンセルvelength stability requirements. This report introduces the structures and the performance of both laser modules.
