Fiber Type Matters When Simulating Optical Links and Latency

Simulating real-world fiber optic links and time delays in the lab environment is both a frequent and necessary task for engineers performing R&D and equipment certification testing processes.  With the evolution to more advanced network architecture, increasing speeds of 400G and beyond, and latency always being a key element, replicating the field network as closely as possible in the lab is critical to ensure systems will perform as expected post-deployment. 

Nokia boasts of 1.52 Tbit/s over single mode fiber

Nokia said it recorded speeds four times above the market’s current standard of 400 Gbit/s over fiber, transmitting at 1.52 Terabits per second (Tbit/s) over 80 km of standard single mode fiber — the equivalent of simultaneously streaming 1.5 million YouTube videos – which is four times the market’s current state-of-the-art of approximately 400 Gigabits per second.

400G QSFP-DD DR4 module is powered by silicon photonics technology

Hengtong Rockley has released a 400G QSFP-DD DR4 optical module based on silicon photonics technology geared for cloud data center networks. The new 400G QSFP-DD module is the company’s first 400G silicon photonics optical module product and is intended for use in next generation cloud-scale data center networks for low-cost, low-power consumption optical connections between switches. The deployment of such 400G transceivers will enable data center networks to deliver a 4x increase in network speed compared to existing deployments using 100G.

Webinar: Data Center Network and Optics Strategies

This webcast begins with a look at the evolving state of data center optics. It examines such questions as what’s unique about data center requirements, why systems vendors are entering the transceiver space as traditional suppliers are leaving it, what role coherent may play and where, and whether data center optics development has become too expensive to encourage potentially innovative newcomers? Panelists will then address how data center networking is affecting optical connectivity requirements and will review the mass adoption of LC and MPO connectors,  new technology for 400 Gigabit Ethernet requirements as well as what the future might hold for such applications as connecting fiber to Photonic Integrated Circuits (PICs) and coupling for co-packaged optics as well as other emerging applications.

Webinar: The Key to 400G

As more cloud service providers and hyperscale data centers migrate to 200 and 400 Gb/s to support 50 and 100 Gb/s servers, active equipment manufacturers have already announced 400 Gb/s switch platforms in response to demand from data center managers. What is involved in creating the right ecosystem for 400 Gb/s Ethernet? What options to data center designers have? This webinar will provide an overview and guidance.

400G to claim big optical port shipments through 2024: Dell’Oro

The growing popularity of 400-Gbps transmission rates will lead DWDM coherent port shipments to reach 1.3 million by 2024, according to Dell’Oro Group. The market research firm states in its latest report that the total optical transport market, which Dell’Oro defines as including multiservice multiplexers and WDM systems, will be worth nearly $18 billion by that year.
