Athermal AWG DWDM module
Key element of multiplexer/demultiplexer block
AAWG module is the main component of DWDM equipment multiplexer/demultiplexer blocks. AAWG allows working in a wide temperature range. AAWG module is an entirely passive device due to providing compensation of chip thermal expansion. The module does not include components of the system that requests electrical supply.
AAWG module is designed for multiplexing or demultiplexing of optical signal in the band 1525-1565 nm (C-band), configurations of the device using from 40 to 96 channels with a step of 100 or 50 GHz.
Fields of application:
- Data transmission system DWDM
Features:
- Low losses
- High insulation
- Entirely passive module
- Compact case
- Wide temperature range
