This week marked the fifth anniversary of Nortel Networks announcing its coherent technology.
Mike Adams (who's now a vice president at Ciena Corp.) clued me in on it Thursday. Sure enough, it was mid-March 2008 when Ryan Lawler (who's now doing things like interviewing Will Arnett) wrote: Nortel Trots Out 40Gig.
We didn't call it "coherent" then. Nortel was emphasizing the name of the modulation scheme, the oh-so-catchy dual-polarization quadrature phase-shift keying (DP-QPSK).
Not everyone believed in coherent from the get-go, Adams remembers -- and why not? Nortel's would be one of many different, incompatible 40Gbit/s schemes to emerge for optical line-side transmission.
But Nortel got some carriers on board quickly. And months later, coherent detection became the de facto 100Gbit/s standard when the OIF set its 100Gbit/s framework, including the choice of DP-QPSK as the sole modulation format. (See Nortel Rolls On With 40-Gig and OIF Steps In to Fill the 100G Void.)
Now at the 2013 OFC/NFOEC, coherent is all we'll talk about, although there'll be some quadrature amplitude modulation (QAM) to go along with the DP-QPSK.
We did give Nortel a lot of credit for trailblazing 100Gbit/s coherent (at least, that's how I remember it), but the five-year mark still provided a nice excuse to pause and reflect for a minute. Now back to OFC/NFOEC planning.

re: Coherent Turns 5 Yep, and you would have thought for this story I'd have been able to find more pictures, news coverage, etc from 2008.-á Even digital stuff seems to fade away.-á I'm sure the BK process didn't help that at all.

re: Coherent Turns 5 We just posted an in-depth story that starts back over a decade ago when coherent was just an idea, and interviewed some of the R&D engineers who were involved in its early development.-á Some nice pictures of old people and products too.-á
Light Reading is spending much of this year digging into the details of how automation technology will impact the comms market, but let's take a moment to also look at how automation is set to overturn the current world order by the middle of the century.
Understanding the full experience of women in technology requires starting at the collegiate level (or sooner) and studying the technologies women are involved with, company cultures they're part of and personal experiences of individuals.
During this WiC radio show, we will talk with Nicole Engelbert, the director of Research & Analysis for Ovum Technology and a 23-year telecom industry veteran, about her experiences and perspectives on women in tech. Engelbert covers infrastructure, applications and industries for Ovum, but she is also involved in the research firm's higher education team and has helped colleges and universities globally leverage technology as a strategy for improving recruitment, retention and graduation performance.
She will share her unique insight into the collegiate level, where women pursuing engineering and STEM-related degrees is dwindling. Engelbert will also reveal new, original Ovum research on the topics of artificial intelligence, the Internet of Things, security and augmented reality, as well as discuss what each of those technologies might mean for women in our field. As always, we'll also leave plenty of time to answer all your questions live on the air and chat board.
