Yenista Optics SA, a provider of fiber optic T&M solutions for both laboratories and manufacturing, announces the release of its WSM-160, a manual optical tunable filter.
Tunable filters have always been used in optical manufacturing and laboratories, mainly to extract one channel from a DWDM signal or to cut adjacent ASE noise induced by amplifiers. With latest development of next generation ROADM/DWDM/CWDM systems, the tunable filter usage is growing and latest products also open new doors for experiment. With an a wavelength tuning range from 1495 to 1650nm and a bandwidth tunable range from 0.25 nm to 80 nm; the WSM-160 allows engineers to extract channels with low insertion loss and no distortion of signal thanks to its flat top shape- a major improvement compared to Gaussian filters. It is the perfect tool for studying new modulation formats, cascaded ROADMs, high bit rate transmission, pulse shaping or even 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.”
