Description
The CW20P-type laser modules are designed for use in transmission systems and high-speed data communication applications. The device supports 20 wavelengths. The module uses an RS-232 interface to adjust various module functions such as wavelength. In addition, the interface provides accessibility to the alarm and monitor outputs.
