Add/drop platform and wavelength-selective switches

Oclaro announced an add/drop routing platform for next-generation reconfigurable optical add/drop multiplexers (ROADMs). The platform, which supports colourless, directionless, contentionless (CDC) and flexible grid ROADMs, can be tailored to a system vendor's requirements and includes such functions as cross-connect switching, arrayed amplifiers and optical channel monitors.

 


"If we make the whole thing [add/drop platform], we can integrate in a much better way"

OFC/NFOEC 2013 industry reflections - Part 4

Gazettabyte asked industry figures for their views after attending the recent OFC/NFOEC show. 

 

"Spatial domain multiplexing has been a hot topic in R&D labs. However, at this year's OFC we found that incumbent and emerging carriers do not have a near-term need for this technology. Those working on spatial domain multiplexing development should adjust their efforts to align with end-users' needs"

OFC/NFOEC 2013 industry reflections - Part 3

Joe Berthold, vice president of network architecture, Ciena

The two topics that received the most attention, judging from session attendance and discussion in the hallways, were silicon photonics and software-defined networking (SDN). I predict that next year those who wish to capitalise on this popularity wave will be submitting papers on SDN-enabled silicon photonics.
