II‐VI Incorporated of Pittsburgh, Pennsylvania USA, announced that it is accelerating shipments of low noise optical amplifiers with integrated tunable filters for 400 Gb/s DWDM transponders. Geographically dispersed datacenters use high bit rate DWDM transponders to enable interconnectivity.Thanks to an integrated wavelength-tunable optical noise filter, II-VI says their low noise optical amplifiers boost the optical power of the transmitted signal with high fidelity to improve the reach of 400 Gb/s DWDM transponders.
“Our optical amplifier technology platform with integrated tunable filter announced in early 2015, generated strong market demand,” said Dr. Sanjai Parthasarathi, Vice President, Product Marketing and Strategy, Optical Communications Group. “We are now ramping up production of our low noise optical amplifier module designed for 400 Gb/s DWDM transponder line cards.”
According to II-VI, higher transmission rates increase the difficulty of distinguishing optical signal from noise at the receiver. Tunable optical filters filter out amplified spontaneous emission, the most significant contributor to optical noise.
II-VI designs and manufactures in-house a complete portfolio of tunable optical components, 980 nm pump lasers, and miniature hybrid micro-optics to provide vertically integrated optical amplifier solutions. The company’s low noise optical amplifiers are Telcordia qualified at the individual component level and as a module. The low noise optical amplifiers are commercially available as a full assembly or in various sub-assembly configurations.
