    The ODC (Optical Direction Coupler) is 3 ports passvie optical component based on thin film filter technology. The ODC is used for dividing two groups of wavelengths into single fiber. One group is 1471/1491/1511/1531, the other is 1551/1571/1591/1611. Which is designed for bi-directional dual band CWDM modules.
