Check that the fiber optic transceiver is firmly inserted into the slot on the line card.
Check that both ends of the fiber optic cable are securely connected to the ports on the transceiver and end node.
Verify that the end node is powered on and operating properly.
Review the operating specifications of the fiber optic transceiver and end node to verify that the devices have the same speed and duplex mode.
Check that the operating specifications, including wavelength and maximum operating distance, of the transceiver are compatible with the fiber optic port on the end node.
Make sure that you are using the appropriate type of fiber optic cable and that the cable length does not exceed the allowed maximum distance. The cable specifications for the transceivers are provided in the installation instructions that ship with the modules.
Use a fiber optic tester to test the whether the optical signal is too weak (i.e., sensitivity) or too strong (i.e., maximum input power). The operating specifications of the fiber optic transceivers are shipped with the units.
Try replacing the fiber optic cable.
Check the two strands of the fiber optic cable to be sure that the receive fiber connector is connected to the transmit connector on the remote end node, and that the transmit fiber connector is connected to the receive connector on the end node.
