Dual band pass filter (DBPF) applications are at the leading edge of fiber optical modules and systems. Using DBPFs is a new concept in multiplex and de-multiplex module design used in optimizing wavelength ranges or channel management. The application of DBPFs makes it possible to reduce the component quantity in optical modules, enhances their performance, […]

Introduction As data storage and computing resources move into the cloud the demand on data centers for storage and data transfer capacity has increased dramatically over the last decade (ref. 1). Stored data needs to be accessed and transferred constantly to and from these datacenters as well as within the data center and this has […]
