NeoPhotonics has added Class 60 versions of its Coherent Driver-Modulator (CDM) and Intradyne Coherent Receiver (Micro-ICR) to its suite of High Bandwidth Coherent components. The components work together to enable customers to implement single wavelength data transmission near 1 Tbps over data centre interconnect (DCI) distances, and long-haul 400-500 Gbps transmission. 

The new Class 60 Coherent components extend the highest speed over distance performance of its existing Class 50 products by increasing the 3 dB bandwidth from 50 GHz to 60 GHz, the company said. The Class 60 suite improves on the currently shipping Class 40 components, and allows increasing symbol rates from the existing 64+ Gbaud rate to the higher 100+ Gbaud rates. 

The 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 800Gbps and above data rates per wavelength applications. 

The Class 60 suite's Class 60 CDM and Class 60 Micro-ICR components are designed to work together with NeoPhotonics “Nano” ultra-narrow linewidth external cavity tunable laser, which cuts the size approximately in half compared to existing Micro-ITLAs, while featuring linewidth and low phase noise with low electrical power consumption.
