NEC announced successful completion of transmission tests across a commercial submarine network using artificial intelligence (AI) and probabilistic shaping at a modulation of 64 QAM. In a joint research publication with Google, NEC says it demonstrated for the first time a spectral efficiency of 6 bps/Hz over an 11,000-km submarine cable segment. The publication's authors assert the demonstration set a spectral efficiency-distance product record of 66,102 bps/Hz in a field trial performed with live traffic neighboring channels. With a potential capacity of over 26 Tbps in the C-band, this is more than 2.5 times the capacity intended for the undersea cable initially, with no additional wet plant capital expenditure, asserts NEC.

According to Yole Développement (Yole), the global LiDAR systems’ market for automotive applications, is showing an impressive growth between 2017 and 2023. From US$726 million to US$5 billion, it should reach a huge 43% CAGR during this period. In addition, the growth should continue until 2032 with a US$ 28 billion market value, for the automotive market segment only. Today, LiDARs and new applications are developing simultaneously. Thus the LIDAR market is directly linked to the development of ADAS solutions and robotic vehicles. Both domains show high growth rates and tremendous enthusiasm.

US foundry offers small companies a unique asset: sharing a multi-project wafer (MPW) on a state-of-the-art production line.A genuine historic moment for US photonics is just a few weeks away. With tool installation now underway, a formal launch of the cutting-edge $612 million AIM Photonics core laboratories is expected in September, officials say. And although that is a bit behind original schedules, leaders are voicing sky-high expectations.

Operators have rapidly adopted coherent transmission since the first deployments of DSP-based coherent technologies to long-haul and submarine networks in the early part of this decade. Coherent technology is now being extended throughout the metro and soon will be deployed in access networks to meet the inexorable demand for bandwidth.

A report shows what will drive the network equipment market for DWDM, ROADMs, and routers over the next five years, though most are still in development. As the demand for data grows, the market for optical networking equipment grows along with it. After all, it takes lots of equipment to deliver network services. A new report from Information Gatekeepers highlights three major contributors to the growth of networking equipment — namely, dense wavelength division multiplexing (DWDM), reconfigurable optical add-drop multiplexers (ROADMs), and routers and switches.

ADVA (FSE: ADV) said that, together with the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt DLR), it has successfully transmitted 13.16 Tbps of data across 10.45 km using free-space optics, setting what it asserts is a new data transmission record for the optical transmission medium. Mirroring a ground to geostationary satellite link, the demonstration is an milestone in providing high-speed broadband to rural and underdeveloped areas, says ADVA.
