For those interested in speeds and feeds, there are two new announcements of note from Asia/Pacific.
The first is that NEC Corp. claims to have completed a successful, error-free 1Tbit/s superchannel transmission on a 5,400-kilometer subsea network using multiple 100Gbit/s Ethernet sub-carriers. The company has shared some of the technical details of how it performed the trial early Thursday morning in a release that, yes, puts the words "software" and "defined" next to each other:
It combined a "software-defined pulse shaper" (an "optoelectronic device that changes the shape of an optical pulse according to values predefined by the user") together with flexible-grid ("transponder capable of modifying the wavelength of the optical subcarrier") real-time 100Gbit/s subcarriers to create a 1Tbit/s superchannel over "commercially available optical fiber [using] cost-effective repeater spacing". The pulse shaper is "designed to mitigate transmission impairments and to offer flexible bandwidth allocation capabilities." NEC claims the technology used "provides a 43 percent improvement over the bandwidth utilization of current commercial systems."
NEC also set up a 1Tbit/s superchannel comprising "full digital" 100Gbit/s subcarriers ("generated with a digital transmitter and detected with a digital-coherent receiver"). NEC explains that "each subcarrier is equipped with a digital signal processor at the transmitter, which can potentially extend the re-configurability to a variable modulation format and/or for variable error-correction capabilities." This, according to the vendor, "enables the 1Tbit/s superchannel to successfully transmit beyond 7,200 km."
Asia/Pacific appears to be the region for superchannel trials. (See Infinera Boasts 8Tbit/s Pipe.)
Meanwhile, regional operator Pacnet has announced plans to add 100Gbit/s capabilities and OTN (Optical Transport Network) switching to its EAC-C2C subsea network, which lands in the major North-East Asia countries and traverses the Pacific to the U.S.
The carrier has previously tested 500Gbit/s superchannels on its submarine network. (See Pacnet, Infinera Demo 500G Super-Channels.)

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.
