H. Takeuchi et H. Yasaka, Low-chirp 10-Gbit/s EA-DFB lasers for photonic network systems - Extendingthe transmission distance of high-hit-rate optical signals, NTT REVIEW, 12(5), 2000, pp. 54-57
A low-chirp electroabsorption modulator integrated distributed feedback las
er has been developed as a compact, low-power-consuming light source for op
tical fiber transmission systems. It enables 10-Gbit/s long-haul single-mod
e optical fiber transmission of up to 140 km with bit-error-free performanc
e. It has long-term stability with lifetime of more than 10 years.
