DiCon announces what it claims is the world's smallest ROADM
The 1-CH MEMS ROADM is based on DiCon's proprietary thin film coating and MEMS technologies. A MEMS mirror is combined with a customized TFF to form a component that de-multiplexes a fixed wavelength, provides add/drop switching, and then multiplexes that wavelength back with the rest of the channels, explain DiCon representatives.

Digital ROADMs: Completing the promise of the optical network revolution
By Geoff Bennett, Infinera -- Due to their analog nature, ROADMs have significant limitations, including limited management capability, lack of subwavelength multiplexing, and the iunability to exploit the full benefits of a GMPLS control plane. However, a new class of ROADM, based on digital technology, is now emerging to address these limitations and deliver a range of additional benefits to the service provider. More...

ROADMs need complementary technologies to realize opex value
By Rich Ramsay, Meriton Networks -- The value proposition of ROADM-based systems is rooted in the opex savings they can deliver. To realize those savings, however, systems require complementary features beyond the ROADM subsystem. More...
