NeoPhotonics' new ROADM module builds on the success of NeoPhotonics' extensive line of planar lightwave circuit (PLC) products, including arrayed wavelength gratings (AWGs) and variable optical multiplexers (VMUXs).
First shipped seven years ago, these products have been embraced by customers around the globe and have accumulated more than 75 million device hours in the field.
"PLC integration is the most cost effective way to produce 2-degree ROADM modules", commented Dr Ferris Lipscomb, VP of Marketing at NeoPhotonics.
"Because NeoPhotonics has extensive design expertise and manufactures PLC devices in large volumes in our own wafer fab, we can readily combine building block elements to increase performance at a competitive cost".
"The incorporation of NeoPhotonics' ultra low loss DWDM MUX/DMUX into the popular ROADM configuration we are currently shipping significantly lowers insertion loss and ripple and increases the passband, which is critical in cascaded DWDM architectures", continued Dr Lipscomb.
"In addition, NeoPhotonics' extremely low power, high isolation, broadband PLC Switch-VOA-Tap (SVT) design enables a much higher level of single-chip integration, significantly reducing the power consumption, size and cost of NeoPhotonics' modules".
"This technology gives us a critical edge in the continuing evolution of PLC ROADMs, which demand significantly reduced power consumption and insertion loss on through and add/drop DWDM channels".
