When it comes to baud rates, is higher always better?

THE ULTIMATE GUIDE TO HIGHER BAUD RATES

This article is brought to you by: 

Since its emergence in the late 2000s, coherent technology has undergone several transitions. First it went from 40G to 100G, then from hard-decision forward error correction (FEC) to soft-decision FEC, and finally from single-rate interfaces to flexible-rate interfaces with additional modulation schemes such as 8QAM (150 Gb/s) and 16QAM (200 Gb/s). 

Infinera adds 400G pluggables to range

Infinera has announced the availability of metro-optimised 400G pluggable optics-based solutions for the XTM Series and GX Series Compact Modular Platforms, designed to bring enhanced flexibility and economics to metro networks.

The magic number

With advances in silicon technology gathering pace, Keely Portway discovers three main ways they are being leveraged to enable the evolution of coherent optical engines
