ECOC 2015 Review - Part 1

Part 1: Line side announcements

• Several companies announced components for 400 gigabit optical transmission
• NEL announced a 200 gigabit coherent DSP-ASIC
• Lumentum ramps production of its ROADM blades while extending the operating temperature of its tunable SFP+

400 gigabit

Oclaro, Teraxion and NeoPhotonics detailed their latest optical components for 400 gigabit optical transmission using coherent detection.

Oclaro and Teraxion announced 400 gigabit modulators for line-side transmission; Oclaro’s based on lithium niobate and Teraxion’s an indium phosphide one.

NeoPhotonics outlined other components that will be required for higher-speed transmission: indium phosphide-based waveguide photo-detectors for coherent receivers, and ultra-narrow line-width lasers suited for higher order modulation schemes such as dual-polarisation 16-quadrature amplitude modulation (DP-16-QAM) and DP-64-QAM.

JDSU's Brandon Collings on silicon photonics, optical transport & the tunable SFP+

JDSU's CTO for communications and commercial optical products, Brandon Collings, discusses reconfigurable optical add/drop multiplexers (ROADMs), 100 Gigabit, silicon photonics, and the status of JDSU's tunable SFP+.

"We have been continually monitoring to find ways to use the technology [silicon photonics] for telecom but we are not really seeing that happen”

Reflections 2011, Predictions 2012 - Part 2

Gazettabyte asked industry analysts, CEOs, executives and commentators to reflect on the last year and comment on developments they most anticipate for 2012. Here are the views of Verizon's Glenn Wellbrock, Professor Rod Tucker, Ciena's Joe Berthold, Opnext's Jon Anderson, NeoPhotonics' Tim Jenks and Vladimir Kozlov of LightCounting.

Glenn Wellbrock, Verizon's director of optical transport network architecture & design

The most significant accomplishment from an optical transport perspective for me was the introduction of 100 Gigabit into Verizon's domestic - US - network. 

"The key technology enabler in 2012 will be the flexible grid optical switching that can support data rates beyond 100 Gigabit"
