Passive multiplexing AWG card is a passively multiplexing/demultiplexing device based on optical principles, which is used for multiplexing and demultiplexing of optical signals in optical communication systems. It consists of a group of parallel optical waveguide arrays, each optical waveguide array contains a group of step-by-step branching and step-by-step merging waveguides, the length and width of these waveguides are precisely designed and manufactured in order to achieve a specific Wavelength separation effect.

 

When the optical signal enters the AWG card, the optical signals of different wavelengths will be separated to different output ports, so as to realize the functions of multiplexing and separation. AWG card is a passive device that does not require external power supply or control signals. It has the advantages of low insertion loss, low crosstalk, high channel count, high stability, etc. It is widely used in optical network, data center, cable TV and other fields.
