B. Clesca et al., MULTIWAVELENGTH GAIN FLATNESS ASSESSMENT OF FLUORIDE-BASED FIBER AMPLIFIERS USING A CIRCULATING LOOP, Electronics Letters, 30(16), 1994, pp. 1308-1309
Using an 8 channel multiplex ranging over 28nm and a circulating loop,
the gain excursion and the signal-to-noise ratio discrepancies betwee
n channels were measured against the number of in-line fluoride-based
fibre amplifiers. 27nm 6dB gain bandwidth was observed after six fluor
ide-based amplifiers.
