II‐VI announces miniature MEMS tunable optical filter
II‐VI has developed a miniature tunable optical filter designed for high-speed, high-density optical transceivers. Using a tunable optical filter to remove noise from a transmitter improves the signal fidelity and increases transmission reach, which will be essential to the performance of high-speed advanced complex modulation formats such as such as 64QAM with Nyquist filtering.
