Transforming Network Infrastructure Week in Review: Cisco, Coriant, IDT

February 25, 2017

This week’s Transforming Network Infrastructure was a grab bag of news that included everything from a Cisco-Fiber Mountain connectivity solution, to Coriant’s new open line system features, to Integrated Device Technology’s move to purchase GigPeak.

The Cisco-Fiber Mountain news involves the latter company developing an extension to its Glass Core Fiber Port Aggregators so they can interoperate with Cisco’s NCS 1002 optical transport platform. That solution, called the LS-2520 QSFP Breakout, allows for direct porting to the Cisco NCS 1002.

It features eight 250 gigabit per second dense wave division multiplexed trunk ports as well as 20 QSFP ports. That provides for up to 2 terabits per seconds of transport capacity within and between data centers or points of presence. (QSFP stands for quad small form factor pluggable. It’s a compact, hot-pluggable transceiver technology.)

The Coriant news, meanwhile, tells of the story of how that supplier has improved upon its optical line system with the addition of AC power and front-to-back airflow. The 7300 OLS design also makes better use of rack space, Coriant says.

important theme in data centers today. Companies like Facebook have led the way on this, but now some of the telcos and their suppliers are getting involved as well. For example, Verizon has recently been working with Radisys on a new rack architecture that leverages some new thinking about power and shared access. That involves using racks that are the standard 19-inch size, but offer the ability to plug in from the front, while providing optical and power connections on the back. In this architecture, all the power comes from a shared power source, so it’s efficient from a AC to DC perspective, and it’s efficient from a phased balance perspective. For more details on some of these efforts, look for the upcoming 2Q issue of INTERNET TELEPHONY magazine.)

As for the above-mentioned acquisition, that has IDT buying GigPeak for $250 million in cash. IDT develops RF, real-time interconnect, sensor, and wireless power system-level solutions. GigPeak is a semiconductor IC and software solutions provider.

Day 4, Cisco Live! - The Wrap

Day 4 was the final day of our first ever Cisco Live! We had a great show, with many great conversations and new connections with existing and potential end users, resellers, partners and job hunters.

Day 3, Cisco Live!

Day 3 of Cisco Live is history! For Fiber Mountain, we continued to enjoy visits from decision makers and influencers who were eager to share their data center and structured cabling challenges.

Day 2, Cisco Live!

Tuesday was Day 2 of Cisco Live for Fiber Mountain and we continued to experience high levels of traffic, with many high value decision makers and influencers visiting our booth. One very interesting difference from most conferences I attend is that there are no titles on anyone's show badges. This allows open conversations without people being pretentious. I think this is a very good idea.

Day 1, Cisco Live!

Fiber Mountain is exhibiting at Cisco Live! In Las Vegas for the first time ever! Our first day was hugely successful from just about any perspective - from quantity and quality of booth visitors to successful meetings with customers.
