iolon Offers Tunable Optical Band-Pass Filters

iolon, a start-up based in San Jose, California, introduced a line of widely tunable optical band-pass filter products for 50 or 100 GHz channel spacings across the C- or L-bands. Key applications include tunable receivers, ASE suppression, re-configurable OADM and optical performance monitoring. iolon said the filter's design is based on a miniaturized free-space optical monochromator, enabling high adjacent channel isolation, low insertion loss, low polarization dependent loss and low dispersion.
