The XFA tunable filter is an economic alternative to the XTA-50 if you only need wavelength tuning at a fixed bandwidth. The bandwidth of the XFA is factory set to a value in the 50 to 800 pm range chosen by the customer.

The XFA offers the same features as the XTA-50 except for the bandwidth adjustment. The extremely sharp edges ensure a clean cut between the signal and the adjacent channels or noise, while the flat-top square shape ensures data integrity. Those characteristics in combination with the intuitive user-interface make the filter an ideal tool for manufacturing environments.
