A 4 km transmission at 10-Gb/s operation with wide temperature range in 1.3-/spl mu/m InGaAlAs MQW FP lasers

We experimentally and theoretically demonstrated that transmission was over 4 km by using InGaAlAs Fabry Perot MQW lasers over a wide temperature range. We also present a new approach for estimating coefficient k of mode partition noise which we confirmed by transmission over 2 km in dark fibers with zero dispersion over the 1.29 to 1.33-/spl mu/m wavelength range.
