FIBER OPTICS FEATURES
Multiband Optical Filters Are Telecom Networks' Multitaskers Jan 27, 2021 — Multiband optical filters have long been used in applications such as fluorescence spectroscopy, astronomy, and 3D cinema, to name a few. The ability to combine more than one spectral band into a single optical filter can enable flexibility of system design and reduce the number of components and the costs needed to achieve a desired functionality. Optical filters have always played a key role in fiber optic telecom systems. They provide the wavelength selectivity needed for optical add-drop...
