Yenista and Cornes Dodwell demo tunable filter at FOE

Jan. 18, 2008
JANUARY 18, 2008 -- The new version of the WS40 tunable filter provides an option for customers that require low insertion loss in combination with a predetermined bandwidth.

JANUARY 18, 2008 -- At the Fiber Optics Expo (FOE) held this week in Tokyo, Yenista Optics (search for Yenista Optics) demonstrated a single-bandwidth version of its WS40 tunable filter. The product was showcased in a live demo at the booth of Cornes Dodwell, Yenista's sales partner for the Japanese market.

The new version of the WS40 is a fast tunable filter that the company claims has a FWHM of 0.5 nm in combination with low insertion loss. The filter has a tuning range of 120 nm from 1515 nm to 1635 nm with insertion loss of typically 1.5 dB and guaranteed below 2.0 dB. Tuning speed between arbitrary wavelengths is typically 40 m/sec while providing 10-pm wavelength accuracy. The PC-based platform of the tunable filter is interfaced through an 8.4-inch touch screen with intuitive software, which includes a routine for automating bit-error-rate testing in DWDM systems: A user-defined sequence of channels with corresponding measurement intervals. Remote control is provided through Gigabit Ethernet (RJ45).

At last year's ECOC in Berlin, Yenista introduced the WS40 with selectable bandwidth and FWHM from 0.3 to 1.0 nm, allowing the customer to determine optimum filtering bandwidth. The selectable bandwidth version of the filter has insertion loss of typically 4.5 dB, guaranteed below 6.0 dB. The new version of the WS40 provides an option for customers that require low insertion loss in combination with a predetermined bandwidth.
