Abstract
The impact of fiber chromatic dispersion and an isolated mode hop on the bit-error performance of an external-cavity diode laser newly designed for uncooled wavelength-division-multiplexing (WDM) applications was investigated. Bit-error-rate measurements confirmed that the power penalty resulting from optical waveform distortion after a transmission through 80 km of standard single-mode fiber (SMF) was suppressed to about 1 dB. Moreover, it was confirmed that the deterioration in the bit-error performance caused by an isolated mode hop can be disregarded.
