For 1.55‐μm MQW‐DFB lasers, the dependence of transmission characteristics under 2.5‐Gb/s modulation on the number of wells is investigated experimentally and theoretically. The fiber length is 70 km and the total dispersion is 1470 ps/nm. Extremely low power penalty of 1.3 dB is obtained for a 12‐well laser with large differential gain of 7.1 × 10 −16 cm 2 . © 1994 John Wiley & Sons, Inc.
