Paper Abstract

The current status of the praseodymium doped fluoride fiber amplifier (PDFFA), the preferred fiber amplifier at 1.3 micrometers , is reviewed. Small-signal gains of 30dB are achievable, together with output powers of 200mW, and a noise figure of 4-7dB. 1.3- micrometers transmission offers the advantage of operating near the zero dispersion wavelength of standard telecommunications fiber, allowing high speed links with simple transmitters.
