Acacia, now part of Cisco, has announced a pair of new 400G QSFP-DD coherent pluggable optical transceivers. High-speed highly compact and scalable optical integrated circuits in silicon Industry leading innovative low power and high optical performance DSP design Behind Acacia's commitment is a team of industry leaders with a broad range of experience in optical systems, networking, silicon photonics and. Today, Acacia, now part of Cisco, is adding to its award-winning, comprehensive portfolio of 400G coherent pluggable solutions, based on its Greylock 7nm Digital Signal Processor (DSP), with the new Bright 400ZR+ and ER1 400G pluggable coherent optical modules. Early adopters of Acacia's 400G. Acacia 400G CFP2-DCO Pluggable Coherent Optical Module CFP2-DCO Coherent transceivers are fully tunable across the 50GHz ITU-T grid frequency range, and support flex-grid DWDM tuning. It can soft-select among three phase modulation schemes for different applications, which is used with M6500 and. Our module products are powered by our internally developed and purpose-built coherent Digital Signal Processor (DSP) Application-Specific Integrated Circuits (ASICs) and silicon Photonic Integrated Circuits (PICs), which are engineered to work together and integrate numerous signal processing and. Acacia 100G/200G CFP2-DCO coherent optical modules are designed to support access/remote PHY aggregation, wireless backhaul, metropolitan/long distance service providers and data center networks Networkinterconnection. The module is designed to follow the carrier-centric OpenROADM MSA and the 100G. Acacia Communications Inc of Maynard, MA, USA (now part of Cisco) — which develops and manufactures high-speed coherent optical interconnect products — has expanded its client optics components portfolio with new products that leverage its proven digital signal processing (DSP) and silicon.
