Fiber-Coupled Tunable Optical Filters Flexible Tunable Filters Our line of fiber-coupled tunable filters allows you to manipulate your optical signals, capturing wanted wavelengths and blocking unwanted wavelengths. Our exchangeable filters allow you to alter the filter shape, center or bandwidth without changing your fibers. High Quality Filter Foundry Partner For the last 6 years, dbm Optics and Koshin in Japan have had a partnership to provide high quality thin film filters in fiber coupled adjustable mechanisms for lab use. Koshin is a larger Thin Film Filter company, based just outside of Tokyo, Japan. Koshin have been in business making thin film filters since 98. Applications Band separation DWDM CWDM FTTH Channel selection DWDM CWDM FTTH Channel blocking Eliminating ASE Band blocking Eliminating unwanted filter FSR repetition Quality Standards Both dbm Optics and Koshin adhere to the tightest process controls and quality standards. In addition, our filter operations are ISO-9 accredited.
