XTA-50: Automatic Ultra-Selective Filters with Narrow Bandwidth

XTA-50 Data Sheet XTA-50 Data Sheet

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 (see Related Products).

Yenista Optics XT filters are also available:

- in automatic version with a fixed bandwidth: XFA
- in manual version: XTM-50
