Abstract
The present invention discloses a time/wavelength-division multiplexed passive optical network (TWPON), which has an optical splitter () and a waveguide grating router (WGR) () disposed at a remote node (RN) (). The optical splitter () and the WGR () 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.
