Yenista Optics has added the PMF option on its manual optical tunable bandpass filter, the WSM-160 BP. This option offers an optimized wavelength range over the C-band from 1525 nm to 1570 nm and passband adjustment from 0.25 to 45 nm.

The standard WSM-160 was designed to enable engineers to extract channels with low insertion loss and no signal distortion thanks to its flat-top shape. It is particularly well suited for studying new modulation formats, cascaded ROADMs, high bit rate transmission, pulse shaping, and optical parametric amplification. The PMF option addresses specific needs in new modulation formats where polarization multiplexing is utilized.
