Scaling Optical Fiber Networks: Challenges and Solutions
Increases in consumer demand and machine-to-machine network traffic are creating big challenges for letting optical communications continue to scale cost-effectively. Meeting those demands will require new forms of optical parallelism.
by Peter J. WinzerROADMs: Reconfigurable Optics for Agile Networks
Flexible, dynamic wavelength routing has already helped drive vast gains in optical network capacity—and the capabilities of wavelength routing’s core element, the ROADM, continue to evolve.
