NeoPhotonics Demonstrates 64 Gbaud COSA for Coherent 400G-1.2T Applications on OFC2018

SAN DIEGO, Calif., March 12, 2018 – NeoPhotonics Corporation (NYSE: NPTN), a leading designer and manufacturer of advanced hybrid photonic integrated circuit based modules and subsystems for bandwidth-intensive, high speed communications networks, today announced it will demonstrate its 64 Gbaud Coherent Optical Sub-Assembly (COSA) at the Optical Fiber Communication Conference and Exhibition in San Diego, March 13 to 15.  The NeoPhotonics 64 Gbaud COSA is based on the same technology as its industry leading ICR product line and its recently introduced Coherent Driver Modulator (CDM) and integrates these two functions into a single compact package. 

The 64Gbaud COSA is designed to work with NeoPhotonics ultra-narrow linewidth external cavity Nano-ITLA to achieve high optical performance in a form factor compatible with coherent pluggable OSFP modules.  A 400ZR OSFP module with the COSA and Nano-ITLA operating at 64 Gbaud and 16 QAM will also be demonstrated using off module processing.  The COSA and Nano-ITLA can also be used for single lambda 600G and two lambda 1.2T using 64 Gbaud and 64QAM.

The 64Gbaud COSA contains a coherent I/Q modulator co-packaged with drivers, as well as a coherent receiver co-packaged with trans-impedance amplifiers.  The COSA is based on NeoPhotonics photonic integration technology and uses design elements that have been proven in production.  The COSA is approximately the same size as either the discrete CDM or the discrete Micro-ICR, and so cuts the component footprint in half while simplifying fiber management and board layout.  When the COSA is combined with NeoPhotonics external cavity Nano-ITLA, which is also half the size of its Micro-ITLA predecessor, the size of the optics for next generation modules is cut in half without impacting performance, meeting the requirements for OSFP pluggable modules and compact daughter cards.

"We are pleased to demonstrate our new 64 Gbaud COSA operating with our new Nano-ITLA at OFC, showing that we have maintained all of the performance of the discrete components, but at half the size," said Tim Jenks, Chairman and CEO of NeoPhotonics. "These compact and highly integrated components are well suited for 400G and 600G per lambda applications that require very compact optical components," continued Mr. Jenks.

NeoPhotonics will exhibit its 64 Gbaud COSA along with its suite of coherent components for 600G and 1.2T at the OFC Optical Networking and Communication Conference & Exhibition in Booth 3322 in San Diego, March 13th to 15th, along with its broad family of products for high speed applications.


In addition, NeoPhotonics will participate in a panel discussion and will co-author two papers as part of the OFC technical conference.
