Abstract
High-speed measurements of the output power level of a laser are obtained by using a high-speed optical monitoring device that is capable of producing an electrical feedback signal having an amplitude that varies based on the amount of light impinging on the monitoring devices. These signals are processed and measured by OTDR circuitry and sampling circuitry within the transceiver module to allow measurements to be made in the transceiver module to detect breaks, defects or discontinuities in the transmit fiber, BER, mask margin, jitter, rise and fall times, logic 1 level, logic 0 level, crossing level of rise and fall times, double tracing anomalies, hits in the eye region, etc.
