The utility model relates to a novel real-time monitoring device for optical fibers, and the device is characterized by comprising an optical time-domain reflection module, a network management module and an optical switch module; the optical time-domain reflection module is connected with the network management module and the optical switch module; the network management module is connected to a monitoring host via a network interface, and achieves management functions under the control of the monitoring host; and the optical switch module is connected with the optical fibers to be tested. The novel real-time monitoring device for optical fibers is reasonably designed, and can detect line faults in time, thereby greatly raising the efficiency of maintenance and achieving effective management of a Q / EPON optical system; meanwhile, modular design is employed, the number and the type of monitoring units and the number of monitoring modules are determined based on the number of optical fibers to be actually mo
