Having released 64-Gbaud Class 40 products for 600-Gbps coherent applications, NeoPhotonics Corp. (NYSE: NPTN) is now moving to 800 Gbps with Class 50 versions of its coherent driver micro-modulator (CDM) and coherent micro-intradyne coherent receiver (Micro-ICR). The Class 50 coherent components support symbol rates from 90 to 100 Gbaud for applications at data center interconnect (DCI) reaches.
NeoPhotonics expects designers will pair the Class 50 components with emerging 7-mm coherent DSPs. (Systems houses have begun to announce such devices; see, for example, “Infinera unveils ICE6 coherent engine, Infinite Network vision” and “Ciena touts WaveLogic 5 for 800-Gbps coherent transmission”). The new components are available in compact form factor packages suitable for use in pluggable modules and compact daughter cards, the company asserts. NeoPhotonics points out they work well with the company’s “Nano” ultra-narrow linewidth external cavity tunable laser.
The Class 50 polarization-multiplexed quadrature CDM features a co-packaged InP modulator with a linear, high bandwidth, differential driver, all in a package compliant with the form factor of the OIF Implementation Agreement #OIF-HB-CDM-01.0. It is designed for low V-Pi, low insertion loss, and a high extinction ratio. The Class 50 Micro-ICR comes in a package compliant with the OIF Implementation Agreement OIF-DPC-MRX-02.0.
"We are currently providing our customers with a matched suite of high-speed Class 40, 64-Gbaud, optical components to support current 600G per wavelength systems, and the addition of Class 50 versions will continue to support our customers as they move to 90-100 Gbaud and nearly 1 terabit per wavelength," said Tim Jenks, chairman and CEO of NeoPhotonics. "As new generations of electronics become available, it is crucial that the optical components are available to complete the suite, in this case realizing near 1 Tbps on a single wavelength."
NeoPhotonics will showcase its coherent component suite in Booth 2923 at next week’s OFC 2019 event in San Diego.
