<p>A fiber optic transceiver (10) adapted for use in an optical fiber data transmission system is capable of detecting fiber connection problems and providing visual or other indications of a problem. The fiber optic transceiver (10) contains a fiber interface, a receiver, a transmitter, and a microcontroller (118). The microcontroller (118) controls the transmitter to modulate ther laser power to transmit test data and the transceiver includes circuitry and microcode to detect fiber connection problems, including reflection and cross connections. This enables trouble shooting during installation and/or reconfiguring the connection automatically, in response to a connection problem, and provides a physical layer link.</p> |
