FEBRUARY 17, 2010 -- Yenista Optics SA has released its WSM-160, a manual optical tunable filter.
Tunable filters have always been used in optical manufacturing and laboratories, says Yenista, mainly to extract one channel from a DWDM signal or to cut adjacent ASE noise induced by amplifiers. With the development of next-generation ROADM/DWDM/CWDM systems, tunable filter usage is growing, and the latest products also open new doors for experiment, the company adds.
With a wavelength tuning range from 1495 to 1650 nm and a bandwidth tunable range from 0.25 to 80 nm; the WSM-160 is designed to enable engineers to extract channels with low insertion loss and no signal distortion, thanks to its flat top shape. This represents a major improvement compared to Gaussian filters, Yenista asserts.
The company says the WSM-160 is particularly well suited for studying new modulation formats, cascaded ROADMs, high bit rate transmission, pulse shaping, and optical parametric amplification thanks to large bandwidth tuning range.
“Yenista has the most complete range of high-end automated benchtop tunable filters on the market with the Xtract and WS series” said Nicephore Nicolas, Yenista's sales and marketing manager. “With this manual version of the WS series, our development team has used its past experience to market high-end filters that surpass all existing manual solutions and therefore customers can now benefit from Yenista’s filter technology at a very attractive price-performance ratio. Operation of the filter is straightforward and it will truly ease the life of all lab engineers.”
