7.1 INTRODUCTION

Optical diagnosis, performance monitoring, and characterization are essential

for ensuring the high quality operation of any lightwave systems. In fact, an

efficient and reliable optical network, such as a passive optical network (PON),

depends on appropriate testing and measurement. During the construction

phase, proper testing is the only way to guarantee that all the required transmis-

sion specifications are met, the network is ready for actual traffic, ...
