Miniaturized DCM for O+E+C Band Dispersion Compensating Module

The miniaturized O+E+C band dispersion compensating module can perform broadband dispersion adjustment in the O+E+C band for standard single-mode fibre (G.652), thereby optimizing the residual dispersion of the system. And it has extremely low insertion loss in the O+E+C band. Based on the design of new BD NDCF fibre and mature and reliable processing technology, the module can improve the performance of optical transmission systems. At the same time, the miniaturized device package dimension can meet the requirements of system miniaturization.
