Product Details

Arrayed waveguide gratings (AWG) are commonly used as optical (de)multiplexers in wavelength division multiplexed (WDM) systems. These devices are capable of multiplexing a large number of wavelengths into a single optical fiber, thereby increasing the transmission capacity of optical networksconsiderably.

GLSUN 50G 80ch AAWG - Application Note

The specifications serve for C-band 80 channels Flat-top MUX/DEMUX Athermal AWG module in DWDM system
