The LambdaDriver® EM1600-ROADM40 module uses an advanced IPLC technology for Reconfigurable ADD/EXPRESS and ultra-low loss DWDM DROP functionality, based on Arrayed Waveguide Grating (AWG) devices. The ROADM can multiplex/demultiplex up to 40 DWDM C-Band channels (carrier wavelengths/frequencies) spaced 100 GHz apart over a single physical fiber. Each channel is fully independent of the others and can carry data at the same rate as a dedicated physical fiber.
