Reveling in ROADMs

For the next few months, Light Reading will be running a Next-Gen ROADM Briefing Center, a little space at http://www.lightreading.com/roadm where we'll round up all the news and information that we cover relating to that most forward-looking of optical networking endeavors.

To help get that site off to a good start, Craig Matsumoto has updated our Buzz Bin entries on two key terms:

  • Wavelength Selective Switch (WSS)

  • Reconfigurable Optical Add/Drop Multiplexer (ROADM)



Click on each linked term for a quick explanation of the technology. In the ROADM entry, you'll get a nice tour of what's been going on in ROADMs for the past few months to get you up to speed.

Of course, that's just a sampling of what's been happening. You might also scan through the fair amount of analyst commentary on optical networking trends of late. Some highlights include:

  • A Peek Into Infinera's PICs

  • Packet-Optical Transport Takes Manhattan

  • 40G: Time for the Third-Party Candidate to Bow Out?

  • Evolving Packet-Optical Transport

  • 100G Hits the Ground Running



Also, you may enjoy this walk down memory lane as we recap below some of our archived resources on the wide world of ROADMs:

  • Trends in Dynamic Optical Networks (2007)

  • Next-Gen ROADMs (2006)

  • Cutting Opex in Optical Networks (2006)

  • Who Makes What: ROADMs (2004)



Keep checking back, as we'll have much more about ROADMs to report in the days to come.

Phil Harvey

Editor-in-Chief, Light Reading

Phil Harvey has been a Light Reading writer and editor for more than 18 years combined. He began his second tour as the site's chief editor in April 2020.

His interest in speed and scale means he often covers optical networking and the foundational technologies powering the modern Internet.

Harvey covered networking, Internet infrastructure and dot-com mania in the late 90s for Silicon Valley magazines like UPSIDE and Red Herring before joining Light Reading (for the first time) in late 2000.

After moving to the Republic of Texas, Harvey spent eight years as a contributing tech writer for D CEO magazine, producing columns about tech advances in everything from supercomputing to cellphone recycling.

Harvey is an avid photographer and camera collector – if you accept that compulsive shopping and "collecting" are the same.
