✦ Synopsis

An efficient gain-flattened C-band Erbium-doped fibre
amplifier is demonstrated using a double-pass configuration with
an IsoGain^TM^ Erbium-doped fibre (EDF). The amplifier
utilizes a double-propagation of signal provided by an optical
circulator at the output end of the EDF to obtain an improved
flat-gain characteristic. At input signal power of -10 dBm, a
flat-gain of 25 dB was obtained from wavelength region from 1528
to 1568 nm. This amplifier has the potential to be used in the
high channel count dense wavelength division multiplexing system
because of its simplicity and low cost.

An erbium-doped fiber amplifier (EDFA) for S-band signal amplification is designed by using a depressed cladding erbium-doped fiber (DC-EDF). The fiber's characteristics are described in terms of the effects of the fiber spooling diameter on the amplifier's performance. In this experiment, the spool
