More Information
Summary:The utility model relates to a miniature DWDM module, comprising a single-fiber collimator which emits an optical signal to a Z-block assembly at a certain incident angle; the collimator array is provided with light receiving parts of which the number corresponds to the number of WDM (Wavelength Division Multiplexing) channels; the Z-block assembly sequentially comprises a first walk-off crystal, a 1/2 wave plate, DWDM (Discrete Wavelength Division Multiplexing) filters, a first 1/4 wave plate, a second walk-off crystal, a second 1/4 wave plate and a high-reflection film, wherein the number of the DWDM filters corresponds to that of WDM channels; the single-fiber collimator and the collimator array are respectively located at one side of a light output surface of the first walk-off crystal, the single-fiber collimator emits an optical signal into the first walk-off crystal, and each light receiving part of the collimator array respectively receives the optical signal which is emitted from the first walk-off c
