Books in 2017: Part 2

Gazettabyte has asked various industry executives to discuss the books they read in 2017. Here, Infinera's Dave Welch and Deutche Telekom's Yuriy Babenko provide their highlights.

 

Dave Welch, founder and chief strategy and technology officer at Infinera

One favourite book read this year was Alexander Hamilton by Ron Chernow. Great history about the makings of the US government and financial systems as well as a great biography. Another is The Gene: An Intimate History by Siddhartha Mukherjee, a wonderful discussion about the science and history of genetics.

 

Yuriy Babenko, senior expert NGN, Deutsche Telekom

As part of my reading in 2017 I selected two technical books, one general life/ philosophy title and one strategy book.

Today’s internet infrastructure design is hardly possible without what we refer to as the cloud. Cloud is a very general term but I really like the definition of NIST: Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction.

Has coherent optical transmission run its course?

Feature: Coherent's future

Three optical systems vendors share their thoughts about coherent technology and the scope for further improvement as they look two generations ahead to symbol rates approaching 100 gigabaud   

Optical transmission using coherent detection has made huge strides in the last decade. The latest coherent technology with transmitter-based digital signal processing delivers 25x the capacity-reach of 10-gigabit wavelengths using direct-detection, according to Infinera.

Since early 2016, the optical systems vendors Infinera, Ciena and Nokia have all announced new coherent digital signal processor (DSP) designs. Each new generation of coherent DSP improves the capacity that can be transmitted over an optical link. But given the effectiveness of the latest coherent systems, has most of the benefits already been achieved?

“It is getting harder and harder,” admits Kim Roberts, vice president, WaveLogic science at Ciena. “Unlike 10 years ago, there are no factors of 10 available for improvement.”

Infinera unveils its next-gen packet-optical platforms 

  • Infinera has announced its first major metro product upgrade since it acquired Transmode in 2015.
  • The XTM II platforms use CFP2-DCO pluggable modules for the line-side optics, not Infinera’s photonic integrated circuit (PIC) technology.
  • Infinera’s XTM II achieves new levels of power efficiency by adopting CFP2-DCO pluggables and a distributed switch architecture.

    Infinera has unveiled its latest metro products that support up to 200-gigabit wavelengths using CFP2-DCO pluggable modules.

    The XTM II platform family is designed to support growing metro traffic, low-latency services and the trend to move sophisticated equipment towards the network edge. Placing computing, storage and even switching near the network edge contrasts with the classical approach of backhauling traffic, sometimes deep within the network.

    Infinera inches closer to cognitive networking

    Part 2: Infinera’s Instant Network

    The second and final part as to how optical networking is becoming smarter

    Infinera says it has made it easier for operators to deploy optical links to accommodate traffic growth.

    The system vendor says its latest capability, known as Instant Network, also paves the way for autonomous networks that will predict traffic trends and enable capacity as required.

    The latest announcement builds on Infinera’s existing Instant Bandwidth feature, introduced in 2012, that uses its photonic integrated circuit (PIC) technology.

    Instant Bandwidth exploits the fact that all five 100-gigabit wavelengths of a line card hosting Infinera’s 500-gigabit PIC are lit even though an operator may only need a subset of the 100-gigabit wavelengths. Using Instant Bandwidth, extra capacity can be added to a link - until all five wavelengths are used - in a matter of hours.

    The technology allows 100-gigabit wavelengths to be activated in minutes, says Geoff Bennett, director, solutions and technology at Infinera (pictured). It takes several hours due to the processing time for the operator to raise a purchasing order for the new capacity and get it signed off.

    Real-time visibility makes optical networking smarter

    Part 1: Ciena's Liquid Spectrum

    Systems vendors are making optical networks smarter. Their latest equipment, combining intelligent silicon and software hooks, can measure the status of the network and enable dynamic network management.

    Ciena recently announced its Liquid Spectrum networking product while Infinera has launched its Instant Network. Both vendors exploit the capabilities of their latest generation coherent DSPs to allow greater network automation and efficiency. The vendors even talk about their products being an important step towards autonomous or cognitive networks.

    Infinera goes multi-terabit with its latest photonic IC

    In his new book, The Great Acceleration, Robert Colvile discusses how things we do are speeding up.

    In 1845 it took U.S. President James Polk six months to send a message to California. Just 15 years later Abraham Lincoln's inaugural address could travel the same distance in under eight days, using the Pony Express. But the use of ponies for transcontinental communications was shortlived once the electrical telegraph took hold. [1]

    The relentless progress in information transfer, enabled by chip advances and Moore's law, is taken largely for granted. Less noticed is the progress being made in integrated photonic chips, most notably by Infinera.

    Next-generation coherent adds sub-carriers to capabilities

    Briefing: DWDM developments

    Part 2: Infinera's coherent toolkit 


    Source: Infinera

    Infinera has detailed coherent technology enhancements implemented using its latest-generation optical transmission technology. The system vendor is still to launch its newest  photonic integrated circuit (PIC) and FlexCoherent DSP-ASIC but has detailed features the CMOS and indium phosphide ICs support.

    The techniques highlight the increasing sophistication of coherent technology and an ever tighter coupling between electronics and photonics.
