Description
AWG (AWG) is the preferred technology in Dense Wavelength Division Multiplexing (DWDM) systems. It is a grating formed by an array of waveguides with equal length differences, utilizing the ability to split waves.
AAWG features
- Low insertion loss
- Low PDL
- Multiple packaging methods
AAWG application
- DWDM transmission system
- Optical add/drop multiplexing
