Class 60 coherent modulator and receiver for 800G and above
In conjunction with the NeoPhotonics ultra-narrow linewidth Nano tunable laser, these Class 60 coherent components are ideal for 96 Gbaud and above symbol rate applications

NeoPhotonics Corporation as announced limited availability of Class 60 versions of its Coherent Driver-Modulator (CDM) and Intradyne Coherent Receiver (Micro-ICR). These components are now shipping in initial quantities to multiple customers and address the next generation of 96 GBaud and above systems.

The Class 60 CDM and Micro-ICR are mechanically compatible with their industry-leading Class 40 counterparts and provide a natural upgrade path to higher baud rates supporting data rates that include 800G applications. Optical system performance improvements enabled by operation at these increased baud rates enable NeoPhotonics customers to pack more data over longer distances for better economics, lower cost per bit, lower operating expenses and lower power consumption, all under the same hardware envelope as they currently enjoy using NeoPhotonics Class 40 components.

Higher symbol rates increase data capacity while maintaining superior optical signal-to-noise ratio (OSNR) and reach performance, thereby enabling the highest speed-over-distance use. The components are available in compact form factor packages suitable for use in pluggable modules and compact daughter cards. Further, they extend the highest speed-over-distance performance of the company’s existing Class 40 products by increasing the 3 dB bandwidth from 40 GHz to 60 GHz. These NeoPhotonics components work together to enable customers to implement single wavelength data transmission near one Terabit per second over datacenter interconnect (DCI) distances, as well as 400 to 500 Gbs transmission over long haul distances.
