II‐VI Inc ramps volume production of low-noise optical amplifiers with integrated tunable filters for 400Gb/s DWDM transponders

Engineered materials and optoelectronic component maker II-VI Inc of Saxonburg, PA, USA (which provides solutions for next-generation optical networks) is ramping up shipments of low-noise optical amplifiers with integrated tunable filters for 400Gb/s DWDM transponders.

High-bit-rate DWDM transponders enable interconnectivity among geographically dispersed data-centers. II-VI's low-noise optical amplifiers improve the reach of 400Gb/s DWDM transponders by boosting the optical power of the transmitted signal with high fidelity due to an integrated wavelength-tunable optical noise filter.

"Our optical amplifier technology platform with integrated tunable filter (announced in early 2015) generated strong market demand," says Dr Sanjai Parthasarathi, VP product marketing & strategy, Optical Communications Group. "We are now ramping up production of our low-noise optical amplifier module designed for 400Gb/s DWDM transponder line-cards."

Higher transmission rates increase the difficulty of distinguishing optical signal from noise at the receiver. Tunable optical filters improve 400Gb/s transmission by filtering out amplified spontaneous emission (ASE), which is the most significant contributor of optical noise.

II-VI designs and manufactures in-house a complete portfolio of miniature hybrid micro-optics, tunable optical components and 980nm pump lasers to achieve vertically integrated optical amplifier solutions. Low-noise optical amplifiers are Telcordia qualified at the individual component level and as a module. They are commercially available as a full assembly or in various sub-assembly configurations.
