Ethernet Alliance hosting virtual booth at BICSI Fall Conference

The Ethernet Alliance announced it will be hosting a virtual booth at the online BICSI Fall Conference & Exhibition, Sept. 29-Oct. 1, 2020. The global consortium dedicated to the advancement of Ethernet technologies seeks to connect with the BICSI professional association’s information and communications technology (ICT) experts focused on building infrastructure, and engage them in its activities in areas such as operational technology (OT) networks and Power over Ethernet (PoE).

Webinar: VIAVI Solutions YouTube LIVE Ethernet Basics

VIAVI Solutions is hosting a live Ethernet Basics session presented by System Engineers, Dave Baker and Peter Desmarais. Attendees will learn Ethernet technology basics including line rates (10M to 400G), types of pluggable optics, link establishment processes, frame structures, key performance indicators, and best practices to test connectivity and service activation. The presentation will include tips and tricks for novices as well as experts.

50 Gbps Automotive Optical Ethernet demo

With the increase in Advanced Driver-Assistance Systems (ADAS), and the industry looking at autonomous vehicles on the horizon, the intelligent car needs growing bitrates to flow through its nervous system. The protocol of choice to implement the communication infrastructure in the car is Ethernet, and the 802.3 Working Group of the IEEE standardization organization is already paving the way to have multi-gigabit per second optical Ethernet in vehicles. A dedicated Study Group is already working on the future IEEE 802.3cz standard.

The Emergence of 400G Pluggable Coherent Optics – Your Questions Answered

Pluggable coherent optics are now being developed for 400G applications with two distinct streams emerging. One is high performance CFP2 based for 1000+km reach and multi-service applications and the other is QSFP-DD ZR (and perhaps OSFP) for DCI and metro Ethernet applications. Both streams present new challenges for test and measurement, not just to meet the demanding technical specifications but also to ensure pain-free integration and deployment in an open ecosystem.

Ethernet: a key enabler in today’s hyper-connected world

One of the most important elements to the success of the internet, even from its earliest days nearly 40 years ago, is Ethernet. Bob Metcalfe, known as the Father of Ethernet, came together with peers to invent and develop the Ethernet local-area network (LAN) technology and its system of packet protocols. Ethernet provides all the necessary specifications to ensure that everything interoperates with each other and it, therefore, ‘disappears’ from the radar of nearly everyone as a concern.

Ethernet consortium announces completion of 800GbE spec

The Ethernet Technology Consortium has announced the completion of a specification for 800 Gigabit Ethernet technology. Based on many of the technologies used in the current top-end 400 Gigabit Ethernet protocol, the new spec is formally known as 800GBASE-R.The 800GbE spec adds new media access control (MAC) and physical coding sublayer (PCS) methods, which tweaks these functions to distribute data across eight physical lanes running at a native 106.25Gbps. The 800GBASE-R specification is built on two 400 GbE 2xClause PCSs to create a single MAC which operates at a combined 800Gbps.

Speed race: Just as 400Gb Ethernet gear rolls out, an 800GbE spec is revealed

Just as the stage is set for 400G Ethernet (GbE) to roll out in force later this year, mainly in hyperscale, telco and large data-center networks, there is a call to boost that speed to 800GbE or even higher in the coming years.The need for increased speed in data centers and cloud services speeds is driven by many things including the continued growth of hyperscale networks from players like Google, Amazon and Facebook, but also the more distributed and mobile workloads modern networks support. But the reality on the ground is that much lower speeds are what’s commonly in use.

HARTING Americas announces launch of breakthrough Single Pair Ethernet technology

Harting Americas has launched their Single Pair Ethernet technologies.SPE communicates across the common industrial Ethernet protocols available today but instead of using 4 or 8 total wires, it accomplishes communication across just two wires, a single twisted pair. It uses Power over Data Line technology to bring communication to the device along with the voltage and amperage needed to power the device. This is hugely beneficial for three reasons:. First, space and number of connections are reduced on the device. Second, the need for an external power supply is eliminated. Finally, devices on the plant floor that have traditionally communicated over Fieldbus protocols can now join the same IP-based network that the rest of the devices on the network are using. This enables peer-to-peer communication, open-loop feedback of all devices, and smart functionality all the way from the main control room down to the individual device.
