摘要： The present invention discloses a time/wavelength-division multiplexed passive optical network (TWPON), which has an optical splitter (21) and a waveguide grating router (WGR) (22) disposed at a remote node (RN) (20). The optical splitter (21) and the WGR (22) can be connected in a cascade or in a parallel such that the present invention can use less number of wavelengths to increase transmission capacity or increase the number of users. A channel fault monitoring (CFM) module provided at an optical line terminal (OLT) is utilized to locate fiber breaks among distribution fibers. The TWPON of the present invention can provide TDM-PON, WDM-PON, and Hybrid PON co-existing platform with less wavelengths channel fault monitoring mechanism.
