Tunable Optical Fiber Filters

 

Both manual and electrical tunable optical filters are available. There are two types of electrical tunable  filter: One is fixed bandwidth, tunable wavelength filter and another one is both bandwidth and wavelength tunable filter.  Tunable filter is based on grating with bandwidth from 0.2nm to 1.3nm. Tunable flat-top filter is based on thin film with bandwidth from 0.8nm to 3nm.
