Abstract :
A simple method of measuring power penalties due to reflection effects on semiconductor lasers in single-mode fibre transmission systems has been developed using a dielectric thin-film-coated fibre endface together with a nearly reflection-free variable attenuator. Field measurements indicate that, for some 560Mbit/s systems, power penalties, resulting from a 15.9% reflection, could be as high as 1.9dB.
