T. Sakamoto et al., FLAT-GAIN OPERATION OF 1580NM-BAND EDFA WITH GAIN VARIATION OF 0.2DB OVER 1579-1592NM, Electronics Letters, 34(20), 1998, pp. 1959-1961
The flat-gain operation of a gain-shifted EDFA (GS-EDFA : 1580 nm-band
EDFA) is described. The GS-EDFA provides a flat gain profile with a g
ain variation of < 0.2 dB for an average gain of 28 dB in the 1579-159
2 nm wavelength range (13 nm). 16 channel x 10 Gbit/s WDM signals are
successfully transmitted over 800 km (80 km x 10 span) of dispersion-s
hifted fibre using the proposed GS-EDFA with no gain equalisation or p
reemphasis.
