Yenista Optics provides PMF option on bandpass filters
Fiber-optic test and measurement instrument supplier Yenista Optics says it now offers a 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, Yenista says.
The WSM-160 was designed to enable engineers to extract channels with low insertion loss and no signal distortion thanks to its flat-top shape. Yenista targets the instrument at such applications as studying new modulation formats, cascaded ROADMs, high-bit-rate transmission, pulse shaping, and optical parametric amplification. The new PMF option addresses requirements for measuring new modulation formats based on polarization multiplexing.
