With the popularization of FTTH, network maintenance requires increasing costs. For network maintenance personnel, the last-kilometer fiber is the most difficult to maintain, because they cannot go into users' houses to perform tests and preventive maintenance. To resolve the test problem of the last-kilometer fiber, we develops the PON endpoint tester (FTTH ONT FINDER) KY***0. It enables maintenance personnel to test links without going into users' houses. Maintenance personnel only need to connect KY***0 to the rear-end of an optical fiber distribution box, and then they can learn about six link states, which help to understand link and ONT status.
