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.

Huawei joins imec to research silicon photonics

Huawei has joined imec, the Belgium nano-electronics research centre, to develop optical interconnect using silicon photonics technology. The strategic agreement follows Huawei's 2013 acquisition of former imec silicon photonics spin-off, Caliopa.
