Can FlexE Close The Gap Between What Networks Require and The Ethernet Rates That Are Standardized?

Flexible Ethernet, or FlexE, originated to solve challenges and inefficiencies in today’s packet and transport networks by providing flexibility and higher capacity, while also enabling the optimal usage of new technologies such as highly flexible coherent optical transmission. Read more »

Unlocking the Benefits of C-RAN with OTN Mobile Fronthaul

Author: Scott Wakelin

Ever since 1987, players from the winning Super Bowl team have been asked the question, “You’ve just won the Super Bowl, what are you going to do next?”  They respond, “I’m going to Disney World!”  This led me to wonder how the U.S. Treasury would answer the same question after the conclusion of the latest AWS-3 auction in which Mobile Network Operators bid almost $45B to secure new licenses – a number that easily surpassed analysts’ estimates of between $10B and $20B.

The Drive for a Higher Capacity Mobile Network

Author: Scott Wakelin

Mobile operators worldwide are investigating new architectures in the Radio Access Network to increase capacity and reduce costs. The C-RAN architecture is the leading solution to this challenge. With C-RAN, baseband processing is moved out of the cell site and into a central location, which creates a new challenge: how to cost-effectively extend the Common Public Radio Interface (CPRI) to the centralized baseband location – a function the industry has named Fronthaul.

Where will the next optical network innovation appear?

Guest Author: Stephen Hardy, Editorial Director, Lightwave

With bandwidth demand growing continuously, optical communications must assume an even more central role in carrier, enterprise, and data center networks alike. Yet merely addressing capacity requirements isn’t enoughLightwave to meet the needs of the network manager. Optical technology must become less expensive, less power hungry, more efficient, more flexible, and more economical to deploy. That means innovation in fiber optics – and in the electronics that support optical transmission – is more important than ever.

To explore where this innovation is needed, what it must look like, and when we might see it, Lightwave has created the Lightwave Optical Innovation Summit, which will take place this July 14-16 in Austin, TX.

What is OTN Switching?

Author: Babak SamimiStorage_title_image

We’re constantly hearing about the phenomenal growth in big data and the resulting increase in traffic on carrier networks worldwide. For example. this interesting infographic by Qmee captures 60 seconds of online traffic in 2013, and the stats are amazing: 350GB of data uploaded to Facebook, two million Google searches, 204 million emails sent, 278,000 tweets—and a whole lot more—every single minute.

Optical network operators have the tremendous challenge of re-architecting their networks to 100G to keep up with this massive traffic growth and doing so profitably.Read more »

Building the 100G OTN Ecosystem

Author: Babak SamimiStorage_title_image

As the optical industry gathers to talk about the future of optical networking at OFC 2014 this week, Acacia Communications and PMC announced a major milestone for the 100G OTN ecosystem.

We’ve achieved successful interoperability between our DIGI 120G OTN Processor and Acacia’s AC100 100G Coherent module, which is important step to show that the ecosystem is ready for the 100G transition.

According to Cisco, big data continues to fuel traffic growth of more than 60% per year in metro networks. As a result, service providers are looking for ways to cost effectively increase optical network capacity. 100G Coherent technology allows transmission of 100Gb/s per lambda over existing fiber plant previously installed for 10G, unlocking a ten-fold increase in fiber capacity and eliminating the need for new fiber.
