To connect the fiber optic cable to the port 1 Clean the fiber ends as follows 1a Gently wipe the fiber end with a lint free swab dipped in isopropyl alcohol 1b Use compressed air to dry completely 1c Visually inspect the fiber end to ensure its cleanliness 2 Carefully align the connector and port to prevent the fiber end from touching the outside of the port or rubbing against other surfaces If your connector features a key ensure that it is fully fitted into the port s corresponding notch 3 Push the connector in so that the fiber optic cable is firmly in place thus ensuring adequate contact If your connector features a screwsleeve tighten the connector enough to firmly maintain the fiber in place Do not overtighten as this will damage the fiber and the port Note f your fiber optic cable is not properly aligned and or connected you will notice heavy loss and reflection 22 AXS 100 Series Setting General OTDR Parameters Setting General OTDR Parameters You can set preferences such as gt gt OTDR Grid You can display or hide the grid appearing on the graph s background By default the grid is displayed Zoom and markers You can display or hide the zoom controls as well as the markers appearing on the graph Reference file You can enable or disable the selection of a reference trace A reference trace is used to compare fibers of a same cable monitor fiber deterioration or c
