Abstract
A diagnostic system utilizes a monitor photodiode and a laser from a fiber optic data link transceiver to perform diagnostic measurements on the fiber optic data link. The diagnostic system includes a multiplexer connected between the encoder and the laser driver of the fiber optic data link. The multiplexer is controlled by a normal op/test mode selector and receives a pulse or pattern for the test mode from a pulse/pattern generator. A signal from the monitor photodiode flows into a pulse/pattern detection circuit which signals a register if a pattern is found. After a reflected pulse is detected, the register captures a count and forwards it to a service processor or system to be analyzed.
