Locking up the Light: Cyber-Security at OFC

Although we seldom think about it, optical networks are a vital part of the economic infrastructure in many parts of the world. Emerging global economies are increasingly reliant on the Internet to promote economic development and address social issues. More established nations are increasingly leveraging cloud computing and the Internet for critical missions involving national security, public health and safety, and financial risk. The United States Central Intelligence Agency, for example, was recognized recently for their efforts in moving critical workloads into the cloud, and in 2013 the President issued executive order 13636, “Improving Critical Infrastructure Cybersecurity”.

Is your network “open” for business?

The optical networking community seems to be embracing open source software in a big way. While industry leading conferences like OFC have always been strong advocates for interoperability and a standards-based approach to networking, this has traditionally been a hardware-focused community.

Given the increasing importance of software in network control planes, data centers, and telecommunication systems, it’s not surprising that OFC will also include a greater emphasis on open source code. This means a faster development cycle compared with the underlying hardware, and more opportunities for innovation as the source code for network control planes becomes accessible to the global programming community.

Getting Ready for the Internet of Things

Some funny things happened while the Internet was minding its own business and incessantly growing into every corner of our lives.  Not that we didn’t see it coming.  When I was giving presentations at optics conferences in the late 1990s, I recall a quote from a major industry trade magazine predicting that the data center of the future would be “software and a network”. As the Internet of Things (IoT) begins to take shape, this prediction is coming true in ways that nobody ever imagined.  And optical networking is positioned to play a major role in the IoT.

Top 4 things that make a good conference and why you should submit a paper to OFC

Despite all the advances in telepresence, video distribution, and webinars, technical conferences remain one of the fundamental ways that our profession shares information.  In fact, the value of a face-to-face conference has become even more apparent in this age of virtual, always-on communication.

40G to 100G Ethernet: By The Numbers

Is it possible to think of something without knowing a word to describe it ?  According to some studies, humans understand the concept of numbers and counting before knowing the words for those numbers.  Perhaps that means that this month’s blog will be easier for everyone to understand, since I’ve found that it’s hard to describe the emerging market for 40 – 100 Gbit/s optical links without using an awful lot of numbers (I needed to use 65 numbers in this post alone, including that last one).

Coherent optical OFDM: What is it good for?

OFDM, short for orthogonal frequency-division multiplexing, is a method of encoding data on multiple carrier frequencies. And the coherent optical OFDM (CO-OFDM) is OFDM data that is being modulated to light frequency and being detected in coherent manner. Though OFDM has been standardized in wireless communication (e.g. IEEE 802.11) for a long time, the CO-OFDM was proposed around 2008 and is a relatively new concept for optical fiber transmission.

What are the possible ways to combat fiber nonlinearity?

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.
