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

Seaborn Networks is expanding its shared spectrum services in the Americas.
One of Latin America’s neutral infrastructure wholesale operators, Ufinet is upgrading its national long-haul network in Colombia, with the aim of doubling the capacity of its current network.
Infinera has expanded its portfolio of open optical networking solutions with a suite of coherent optical pluggables
Australia’s wholesale open-access broadband provider, NBN Co, has completed a successful proof of concept trial of Infinera’s XR optics-based point-to-multipoint coherent optical technology.
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.
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

To some, optical communication product buyers’ expectation that prices continually fall may seem a strange and unnecessary pressure on vendors.

The submarine cable industry is still a very healthy one, with figures from Research and Markets predicting that it will reach $30.8bn by 2026.

The drive toward 5G and beyond has been a key factor in the demand for higher bandwidth and more reliable networks. This has, in turn, brought about a greater appetite for intelligent infrastructure supported by automation.

Arguably one of the biggest topics in optical communications in the past two years has been fifth-generation coherent optics, with a raft of trials and demonstrations, highlighting 800G wavelength achievements taking place.
