Abstract
We experimentally compare the performance of a polarization-independent fiber optic parametric amplifier (FOPA), a discrete Raman amplifier and a commercial erbium doped fiber amplifier (EDFA) for burst traffic amplification in extended reach passive optical networks (PON). We demonstrate that EDFA and Raman amplifiers suffer from severe transient effects, causing penalty on receiver sensitivity >5 dB for traffic bursts of 10 Gbps on-off keying signal shorter than 10 µs. On the other hand, we demonstrate that FOPA does not introduce a penalty on receiver sensitivity when amplifying signal bursts as short as 5 µs as compared to a non-burst signal. Therefore, FOPA used as a drop-in replacement for an EDFA or Raman amplifier allows us to improve receiver sensitivity by >3 dB for short signal bursts. We conclude that FOPA allows substantially increased power budget for an extended reach PON transmitting variable duration bursts. In addition, we identify the maximum burst duration tolerated by each examined amplifier.

Fiber optic parametric amplifiers (FOPA) have been shown to be a promising amplification technology for fiber optical communication with such unique features as a very large gain (70 dB) [1,2] a broad (>100 nm) and flat gain spectrum [3,4,5], and phase sensitive gain allowing for
We have experimentally demonstrated an employment of polarization insensitive FOPA with net gain up to 20 dB for amplification of bursts of 10 Gbps on-off keying (OOK) signal in a 50 km reach passive optical network (PON) architecture
We have compared the performance of a polarization insensitive FOPA with a commercial erbium doped fiber amplifier (EDFA) and a discrete Raman amplifier for amplification of non-burst signal as well as a range of signal burst durations from 70 μs to 5 μs
