What are the possible ways to combat fiber nonlinearity?

By Vivian (Xi) Chen | Posted: 11 March 2014

Fiber nonlinearity is and important concerns for large capacity fiber transmission. When we try to increase system capacity, we occupy a wide optical bandwidth and use a high order modulation format, and thus need a high signal-to-noise ratio (SNR) to keep a certain level of bit-error-rate (BER). Consequently, more and more power is launched into the fiber. It is then that the fiber nonlinear effect becomes a significant factor that degrades signal quality.

OFC Day 2 - Monday, March 10 - Follow the 100G road

By Casimer DeCusatis Ph.D | Posted: 11 March 2014

OFC 2014 is in full swing by now, and as usual I’m feeling a bit overwhelmed by the sheer number of events running in parallel. It’s just not possible for one person to cover the entire conference, but I think you’ll find the highlights that I’ve selected for today’s blog to be both interesting and controversial.

“Unstoppable” Virtualization Means More Network Hits in 2014

By Daniel Tardent | Posted: 6 March 2014

It might be too early to call 2014 the “year of virtualization” but there’s no doubting that use of the technology will grow as will its impact on data center networks. 
Virtualization is good news for server utilization, power consumption and application performance.  But it is not so good for the network, because virtualization adds extra network loads that can have a significant impact on performance and response times.

How to convince your boss that you should go to OFC in 3 easy steps

By Casimer DeCusatis Ph.D. | Posted: 6 March 2014

It’s been said that the Eskimos have 50 different words for snow because it’s such an intimate part of their daily lives.  I’ve been building up my own list of words for “busy”…early last year my work was “really really busy”, then for a month or so it was just “really busy”, and in January it jumped back up to “crazy insane Defcon 4 duck-and-cover busy”.   I suspect your work has been the same – tighter budgets, shorter deadlines, pressure to do more with less.

Optical Networking Trends that Aren’t Spelled SDN

By Scott Wilkinson | Posted: 5 March 2014

Telecommunications and optical networking are going through a welcome resurgence after years of relative stagnation following the telecom crash in the late 1990s and early 2000s. New technological advancements are reinvigorating networks to meet explosive demands from data centers, non-traditional carriers, content delivery networks and ubiquitous video. Trends like Software-Defined Networking (SDN) show great possibilities for enhanced network capabilities, and most vendors now have an SDN story to tout. However, it can be easy to overlook other equally exciting trends in optical networking that are making an even bigger impact today.

Will the Space-Division Multiplexing be the solution for the capacity crunch?

By Vivian (Xi) Chen | Posted: 4 March 2014

The exponential growth of internet traffic at about 2 dB per annum could exhaust the available capacity of single-mode fiber in the near future. But space-division multiplexing (SDM) has been proposed to keep up with capacity improvement. One of the categories of SDM, multi-core fibre (MCF), has multiple individual fibre cores via which signals propagate independently in different fibre cores. The other category of SDM, few-mode fibre (FMF), has one single core in which a few fibre modes are propagating together.

The final countdown until OFC 2014: What to check out besides the main conference program?

By Dr. Ioannis Tomkos | Posted: 4 March 2014

Most researchers attending OFC every year rush to attend interesting talks that are presented at the many parallel conference sessions. The vast majority of people also take some time to visit the exhibition space, check out what new products are on display (by 550 exhibitors!), and observe the exciting live demonstrations at “mobile-labs” and the dazzling booths of the major exhibitors.

Optical Networking: There’s an App for that

By Dr. Ioannis Tomkos | Posted: 24 February 2014

“…so many things I would have done, but clouds got in my way…”
Both Sides, Now by Joni Mitchell, who was ahead of her time predicting the next evolution beyond client-server technology when she released the album “Clouds” in 1969
The future is here, and it’s ready for download.  It’s been said that we live in the App Economy, because of the staggering impact that software apps have had on our daily lives.  Consider that there were a whopping 50 Billion mobile apps downloaded in 2012, and over 20 million installed daily on Facebook.

Software-defined networking and software-defined photonics: Putting the things straight at OFC!

By Dr. Ioannis Tomkos | Posted: 24 February 2014

OFC traditionally focuses on innovations associated with novel photonic devices and subsystems, as well as associated system/network demonstrations. However over the past few years the participants have clearly observed a significant shift in the topics covered by the conference sessions. The applicability and usefulness of advanced electronics in optical communication systems and networks has become evident through a large number of presentations that are focusing on advancements associated with electronic signal processing, FPGAs and ASICs.
