Coherent modulator and receiver for 100+ Gbaud symbol rates
Enables a complete optical system for 800 Gbps and above data rates for single wavelength transmission when combined with the “Nano” ultra-narrow linewidth external cavity tunable laser.

NeoPhotonics Corporation has announced the addition of Class 60 versions of its Coherent Driver-Modulator (CDM) and Intradyne Coherent Receiver (Micro-ICR) to its suite of High Bandwidth Coherent components, addressing the next generation of 100+ Gbaud systems to meet the ongoing growth in demand for bandwidth, especially between cloud data centers.

Optical performance improvement due to increased baud rates enables 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.

These latest Class 60 Coherent components extend the highest speed over distance performance of our existing Class 50 products by increasing the 3 dB bandwidth from 50 GHz to 60 GHz.  The Class 60 suite improves on the currently shipping Class 40 components, and allows increasing symbol rates from the current 64+ Gbaud rate to the higher 100+ Gbaud rates. These components work together to enable customers to implement single wavelength data transmission near one Terabit per second over datacenter interconnect (DCI) distances, and long-haul 400~500 Gbps transmission.

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. These new components are available in compact form factor packages suitable for use in pluggable modules and compact daughter cards. NeoPhotonics Class 60 CDM and Micro-ICR are mechanically compatible to their Class 40 counterparts, and are a natural upgrade path for achieving the higher symbol rates (100+ Gbaud) in order to support 800 Gbps and above data rates per wavelength applications.
