The XTA-50 tunable filter is the reference tool for channel selection or even sub-band extraction thanks to its adjustable bandwidth in combination with very steep edges:

- Standard version: 50 pm (6.25 GHz) to 950 pm (120 GHz) with 500 dB/nm

- Ultrafine version: 32 pm (4 GHz) to 650 pm (80 GHz) with 800 dB/nm

- Wide version: 50 pm (6.25 GHz) to 5000 pm (625 GHz) with 500 dB/nm

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. The filters offer the highest selectivity available on the market and allow for many new fiber-optic transmission experiments.

For efficient operation, it has a user-friendly touch screen interface with four menus:

- Wavelength and bandwidth selection

- Predefined ITU grids: 25, 50, 100 and 200 GHz

- Customer defined grid

- A sequence for systematic bit-error rate testing

The tunable filter can be remotely operated through Ethernet, USB and RS232. GPIB is available as an option through an external converter box
