Multimode wavelengths allow multiple light paths within an optical fiber, enhancing data transmission capabilities. This divergence leads to a varied set of implications in terms of signal quality and bandwidth. Multimode fibers (MMFs) have been a key component in short-reach transmission systems for over 50 years and remain the predominant transmission medium for Vertical Cavity Surface-Emitting Laser (VCSEL)-based short links in data centers. A transmission matrix was used to store the calibration data and a robust algorithm. Here, we utilize these features of multimode fibers to generate all-fiber reconfigurable spectral filters.
