THE ULTIMATE GUIDE TO HIGHER BAUD RATES

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).

A passion for metro

Panelists from Polimi, CTTC, TUE and The University Carlos III of Madrid give their views on the future multi Tb/S metro network

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

Pluggables, Embeddeds, and the Three Vectors of Coherent Evolution

This article is brought to you by: 

Silicon technology enhancements are enabling the evolution of coherent optical engines along three vectors. The first vector maximizes performance by leveraging the most advanced optical features, the second minimizes space and power, and a third integrates systems-level functions that were previously located in the shelf or card.
