OZ Optics has introduced a new tunable filter that has the ability to tune both the centre wavelength and the transmission bandwidth.
Two independently adjustable thin-film filters allow the setting of the lower and upper edges of the pass-band region. With this method, the pass-band can be tuned from 1 to 18 nm FWHM and the centre wavelength shifted by over 40 nm.
The transmission band features a flat-top profile, providing uniformly low losses and low PDL across the pass-band region, and high rejection ratios outside the pass-band. Devices can be custom made for wavelength regions of interest and can use either singlemode or polarisation maintaining fibres.
Two manual controllers to set the upper and lower pass-band regions, with an electrically controlled model due later this year. Applications include WDM testing, spectral filtering, spectral imaging or microscopy, and others.

EXFO has released a new catalogue covering their entire range of products for the fibre-based telecom engineer. Equipment for network engineers and R&D/Manufacturing is covered but, as Elliot Scientific only specialises in the latter, we have made available a special abbreviated version for download from our EXFO product pages.
Examples of the test equipment covered include:
