Wednesday Bytes: Cologix, TTK, TE SubCom, Zayo

March 29th, 2017 by · Leave a Comment

Here's a quick rundown on some news from around the world:

Cologix has some more expansion plans north of the border. The colo and interconnection provider has signed leases in Toronto that will add another 30,000 square feet and 3MW to the company's footprint there, with a third of that coming at 151 Front and two thirds at 905 King a couple kilometers away. Also in the mix is a high-count fiber ring connecting the MMRs in both buildings. Cologix was recently acquired by Stonepeak Infrastructure Partners.

In Russia, TransTelecom says it has shifted all its international backbone traffic onto a longhaul DWDM network. According to the company, 20% of the traffic between Europe and China passes over their infrastructure, and now over their newly upgraded 80-channel, 20,000km transport network. Latency is 153ms between Frankfurt and Hong Kong. TTK is now working on adding on/off ramps to the new longhaul network.

On the submarine cable front, TE SubCom has announced a successful demonstration of some major capacity.  They have achieved 70.4Tbps over 7.600km of fiber using C+L technology.  The solution uses amplifiers with "nearly 10THz of usable optical bandwidth, a transmission line designed to minimize noise accumulation and maximize performance, a new transmission format using multi-dimensional coded modulation with hybrid probabilistic and geometrical constellation shaping, and digital signal processing featuring several stages of non-linear compensation".  I'd tell you what that means, but you'd certainly realize I still need to do some homework first.  But 70.4Tbps is a big number

And late last week, Zayo won a contract with a multinational retailer. Zayo will be providing wavelength and Ethernet connectivity across four continents, including both a transatlantic and transpacific ring and linking locations in the US, UK, and Singapore among others. Zayo has only recently expanded it's reach to Singapore and other destinations in the Far East. This new solution also includes dedicated capacity on SEA-ME-WE-5, taking the network the rest of the way around the globe.
