VPIphotonics Design Suite – Version 11.3

New release of industry-leading design software

for photonic components and optical transmission systems

VPIphotonics Design Suite Version 11.3 provides access to professional application-specific simulation tools and pluggable toolkits. They offer flexible usability, design process, and data analysis capabilities.

Version 11.3 advances the simulation and design flow for many applications: data-aided DSP, FEC, FSO communications, Raman pump optimization, grating couplers, SOAs, multimode coupling, and more.

Our software solutions have been proven by commercial companies and educational institutions who have utilized them to win and successfully execute many research an design projects. With the improved capabilities provided in Version 11.3, our design suite is set to deliver the same outstanding results in the future.

Design Example – 800G FR-4 WDM for Ethernet Applications

This simulation setup demonstrates the transmission of 4*200G
FR-4 WDM channels with 112.5 Gbaud as specified by the 800G
Pluggable MSA technical specification [1]. Four wavelengthseparated
transmitters in the O-band emit a PAM4 signal each. The
outer FEC encoder utilizes Reed-Solomon RS(544,514) coding.
The setup shows the impact of bandwidth limitations on the system
performance and the capability of the RS-based FEC. BER pre-FEC
and post-FEC are used to evaluate the system performance.
