ZTE Boasts 400G Breakthrough

ZTE Corp. sent a bullish optical challenge to the likes of Alcatel-Lucent, Ciena Corp., Coriant, Huawei Technologies Co. Ltd. and Infinera Corp. Friday by announcing what it is calling an "industry first" in the 400Gbit/s market. The Chinese vendor says it has "completed data signaling at speeds of 400 Gbit/s over a distance of more than 5,000 kilometers" using a WDM system with 100GHz channel spacing and a "unique frequency algorithm to overcome the issue of signal degradation," which is significant in long-distance transmissions. "Data was transmitted through 25 reconfigurable optical add-drop multiplexer (ROADM) nodes without an electrical repeater," the vendor boasts, before adding, "the communications capacity of ZTE's system is double that of the most advanced systems currently available in the industry." This might sound like a brave claim but ZTE, which claimed a separate 400Gbit/s world record in September 2012, has reason to be confident about its optical prowess currently, having recently ousted Alcatel-Lucent as the number two optical equipment vendor. (See ZTE Passes Alcatel-Lucent and ZTE Claims 400G Transport First.) Of course, other vendors might argue with ZTE over its capacity claims, and there may be some dispute over whether ZTE is first with 400Gbit/s over more than 5,000 kilometers. (See AT&T Claims 400G Distance Record.) For more

I feel like I clicked on an infomercial for optics. It kind of cheapens the message.

re: ZTE Boasts 400G Breakthrough
Here at Infinera Corp, we accept the 'bullish optical challenge".

This announcement of an 'industry first' from ZTE, while an achievement for ZTE, is a hero experiment. It does not appear to have been run on a live network with commercially available equipment. There is value in these sorts of
experiments as a way to think about what might some day be possible. At the same time it is important to contrast commercially available solutions before calling this hero experiment a credible challenge to the industry.

Infinera started deploying 500G long-haul super-channels in Q2 2012 and has deployed 335 Tb/s of capacity with 27 customer purchase commitments as of March 31, 2013. These 500G super-channel deployments are not hero experiments, these are revenue generating deployments.

Craig Matsumoto correctly points out that Infonetics Research is reporting something different than Ovum regarding who is #2 now in EMEA. Indeed Andrew Schmitt at Infonetics does report someone overtaking ALU for #2 in EMEA, and it is not ZTE. Jimmy Yu of the Dell Oro Group also recently reports that someone overtook ALU for #2 in EMEA for LH WDM, it is not ZTE . Our challenge back to Light Reading is to report the findings of these other industry analysts as well. :-)

As an example of what Infinera is shipping today, we recently announced provisioning 2 Tb/s of capacity in 12 minutes with DANTE in Europe on their production network. The trial involved lighting up four 500G super-channels, and then provisioning a 100GbE service across the link. The trial was timed on a stopwatch, and a time-lapse video of the provisioning process is available here.

Thanks for the opportunity to chime in Ray! We'll hand the microphone over to one of the other teams in the challenge now ... who's up next?

About ZTE's second-place standing ... it depends who you ask. Andrew Schmitt of Infonetics disagrees: https://twitter.com/aschmitt/s...
