Improving DWDM Module Performance With Narrow Dual Band Pass Filters

By Xiaolun Zeng, Michelle Briere, and Rebecca Saaltink, Iridian Spectral

Module designers who create a DWDM module without dual pass filters may save up-front cost, but introducing DWDM dual filters could significantly improve module design by lowering its complexity and/or lowering the module’s insertion loss. Often, module designers using dual pass filters achieve improved overall module performance and/or layout at similar or potentially reduced module build costs.

NDBPF combinations give customers more options in their design of future DWDM modules. Otherwise, the ITU grid provides very restricted module configuration to designers. Providing more options and more adaptability in filter design encourages — and empowers — our customers to try bold solutions to address fitment and performance challenges using narrow, DWDM-like dual band filters to enhance their dual band modules and networks.
