Record-breaking Reach for Low-cost Data Transmission between Data Centers
Researchers in Germany demonstrate highest speeds yet by use of PAM-4 transmission
01 March 2016 - Researchers working at ADVA Optical Networking in Meiningen, Germany, and the Technical University of Denmark have shown real-time transmission of 400Gbit/s (8x50G) over 100 kilometers, using the PAM-4 transmission format. Their system, which uses pulse-amplitude modulation with four discrete levels, significantly improves the cost, space and power efficiency for data center interconnect applications, providing a solution for distances up to 100km.

Finally, the wait is over. While it felt like an eternity, OFC week is now here. A look at the first wave of press releases points us to a belief that the theme of OFC 2016 will be about speed and efficiency. Regarding speed, the press releases were geared around the development of higher speed components and better testing equipment as well as 100 Gbps WDM system deployments. Furthermore, this year efficiency announcements went beyond equipment and include software, services, and organizational changes. SDN is here and companies are positioning themselves to capture the opportunity and extract value.

The use of optics in data centers has been slowly increasing over the last ten years. While there is promise of one converged data center network with Fibre Channel over Ethernet, Discerning Analytics, LLC (DA) is skeptical that we will ever see FCoE be the entire network. What makes most sense economically in the near term is what has been adopted up until now, that is separate storage, LAN and clustering.

First and foremost of these will be the surge of demand in 2016 for the new 100G QSFP28 format. This module, in conjunction with new 100GbE switch silicon from several vendors, will trigger high volume deployment of 100GbE in hyper-scale computing environments.
This is truly an historic moment, as it represents the beginning of a transition from 10G technology, which served customers for the past decade, to faster 25G speeds. During 10G’s reign, we’ve witnessed component vendors deliver tens of millions of modules and the price for them dropping 20% annually. 10G technology was later bootstrapped to serve the demand for 40GbE but this was really an evolutionary, not revolutionary, step.

All the world's data – pictures, video, sounds, and text – has to traverse complex networks of optical fibers that crisscross cities, regions, and countries. To better handle the glut of information, a research team from NOKIA Bell Labs, have developed a new device that could become a crucial component of new flexible and optimized networks.

When it comes to optically interconnected network routers, do you prefer your boxes white or black? We’re discussing whether you believe in “bare metal” hardware that requires you to install your own operating system (white box), or heavily pre-integrated hardware and software solutions (black box). This intriguing question will be examined in depth during the always popular OFC rump session on Tuesday night.

Even though Gigabit Ethernet has been around for more than 10 years now and 10-Gigabit Ethernet for more than seven years, 10G’s adoption rate was slow. Its deployment only passed that of Gigabit three short years ago – in 2013. The reasons are really two-fold: cost and density. As a result, we will see a more fragmented data center market. We expect small and medium enterprise data centers to continue to upgrade their servers from 1G to 10G and use 40G in the aggregation layer, while large and very large may instead transition to 25G using 100G in their aggregation layer.
