II‐VI has announced an uncooled 980nm pump laser module in a compact 3-pin micro-format package designed to meet the stringent reliability and power-efficiency requirements of ultra-compact amplification in current and next-generation high-bit-rate optical transceivers.
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.
