23/01/2012 - Yenista Optics Releases Ultra-Narrow Tunable Filter with 4 GHz Bandwidth

Yenista Optics, a leading manufacturer of fiber optic test and measurement equipment today releases an ultrafine option for its flat-top optical tunable filters, XTM-50/U and XTA-50/U. This option reduces the minimum bandwidth to a market-leading 32 pm or 4 GHz at 1550 nm.

In the development of next generation 100 Gb/s transmission systems, the need for extremely narrow tunable filters has emerged to investigate new modulation formats and their sub-bands. Yenista’s ultrafine option perfectly meets this requirement by providing a higher selectivity to its XT range of filters. The option offers bandwidth adjustability from 32 pm (4 GHz) to 650 pm (80 GHz) and edges of 800 dB/nm - the steepest available on the market! In the standard version, these values are of 50-800 pm and 500 dB/nm respectively. The filters operate in the 1480 to 1620 nm wavelength range and have very low dispersion and loss characteristics.

David Heard, Yenista Optics’ Sales and Marketing Manager for North America says: "Yenista’s filters are designed for the most demanding applications. The high isolation and wide wavelength range surpass all their competitors. Our XT filters are widely respected, particularly, in the telecoms market, and the new ultra-narrow filter will meet the needs of engineers developing new transmission technologies and modulation formats such as OFDM." The filters along with the whole range of Yenista Optics’ test equipment will be showcased from Jan. 24th to 26th 2012 at Photonics West, booth number 4022, in San Francisco, California, USA.
