Abstract

This paper reports the results of temperature cycling and thermal shock tests on commercially available laser modules designed for uncontrolled environments. Components in these installations must withstand a much wider temperature range than that of a telephone central office. The lasers tested in our experiment include receptacle packages, cylindrical packages with pigtails and rectangular packages with pigtails. We have observed some anomalous characteristics such as unstable spectra, non-linear L-I (power versus current), and non-constant front-to-rear tracking ratio. The appearance of these anomalies challenges our ability to economically screen those problem devices.
