100GbE data center shipments surpass 10GbE for first time: Report

Total shipments of 100 Gigabit Ethernet (GbE) data center switch ports increased more than 20% during the full year of 2020, according to a recent report from Crehan Research Inc.
This robust increase, combined with a continuing decline in 10GbE shipments, resulted in 100GbE surpassing 10GbE to become the most widely deployed data center Ethernet switch connection speed, finds the researcher.

HyperLight integrated optical engine pushes Terabit data with lower power consumption

To address the soaring energy consumption for Ethernet, data centers and 5G, HyperLight has designed an integrated electro-optic modulator capable of achieving sub-volt modulators with a 3-dB bandwidth > 100 GHz, a previously impossible voltage-bandwidth achievement. The broadband electro-optic PIC could lead to orders of magnitude energy consumption reduction for next generation optical networking.

OSA | Low loss single-mode polymer optical waveguide with circular cores

Multicore fibers (MCFs), which have multiple cores aligned in one cylindrical cladding, are a promising optical fiber design that dramatically enhances the number of optical channels per cross-sectional area. The Mosquito method is one way to fabricate single-mode polymer optical waveguides with multiple cores while maintaining an identical mode-field diameter among them. The technique forms circular cores in polymer waveguides using a commercially available microdispenser and multi-axis syringe scanning robot.

Single Pair Ethernet in Automation | Ethernet Alliance

With the advent of Single Pair Ethernet (SPE), systems that formerly used RS-485 serial communications can be upgraded with little change to the media and brought into the broader Ethernet network. In addition, Single Pair Ethernet brings the added benefit of remote powering of devices using SPoE (Single Pair Power over Ethernet), a standard like the familiar PoE (Power over Ethernet).

New Single-Pair Ethernet for Condition-Monitoring Applications

New single-pair Ethernet (SPE) physical-layer standards developed by the IEEE are offering new connectivity solutions for communicating asset health insights for condition-monitoring applications. 10BASE-T1L is a new Ethernet physical-layer standard (IEEE 802.3cg-2019) that was approved by the IEEE on November 7, 2019. It will dramatically change the automation industry by significantly improving operational efficiency through seamless Ethernet connectivity to field-level assets.
