摘要：

The design and performance of a 1.65-mum-band single-mode optical time-domain reflectometer (OTDR) with a laser diode source are described. The approach employs a high-power laser diode with a strained-layer InGaAs/lnGaAsP MQW structure which was grown by MOVPE, an InGaAs avalanche photodiode, and methods for reducing the optical wiring loss in an optical unit. A 1.65-mum-band OTDR is realized with a single-way dynamic range of 25 dB at a pulse width of 1.0 mus.
