Basic principles of WDM PON

WDM PON is a point-to-point passive optical network using wavelength division multiplexing technology. That is, in the same fiber, the number of wavelengths used in both directions is more than 3, and the use of wavelength division multiplexing technology to achieve uplink access can provide grea...

Introduction of EPON technology and test challenges faced

The EPON system consists of multiple optical network units (ONU), an optical line terminal (OLT), and one or more optical networks (see Figure 1). In the extension direction, the signal sent by the OLT is broadcast to all ONUs. 8h Modify the frame format, redefine the front part, and add the time... Read More
