“…In this paper we extend our previous work [33,34] experimentally demonstrating a polarizationinsensitive FOPA (PI-FOPA) as a drop-in replacement amplifier for amplification of a bursty traffic in extended reach PON. We transmit a bursty 10 Gbps on-off keying (OOK) signal by 50 km, amplify it by FOPA, a discrete Raman amplifier or a commercial EDFA, before passing it through a variable optical attenuator (VOA) emulating a PON splitter, and detect the signal.…”

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.

“…Finally, the LG variant is for applications where the output signal power is more important than the noise figure, e.g. for extended-reach PON requiring to maximise power budget whilst employing only one amplifier [8].…”

“…These are: operation in virtually any wavelength range, a theoretically unconstrained gain bandwidth, a capability for phase-sensitive amplification (PSA) and an instantaneous response time [1]. Thus, experiments with FOPA demonstrate possibility of operation at arbitrary wavelengths between ~1300 nm and ~1700 nm [2,3], gain bandwidth of ~150 nm [4,5], noise figure (NF) as low as 1.1 dB [6] and a transient-free amplification of signal bursts [7,8].…”

We evaluate and compare performance of three polarisation-insensitive fibre optic parametric amplifier (PI-FOPA) variants. We employ each variant to amplify a set of 21x50 GHz-spaced channels by 12.8±1.5 dB and analyse bit-error rate of an amplified 100G PDM-QPSK channel as power per channel is varied. We demonstrate two variants to provide a competitive noise figure of 6 dB. We envisage each of three PI-FOPA variants to be employed for broadband communications, phase-sensitive amplification and extended-reach PON respectively.

“…The optical parametric amplifier (OPA) is also attracting attention in research as a wideband optical amplifier outperforming the EDFA band. OPAs utilizing nonlinear optical processes have been studied using periodically poled LiNbO3 (PPLN) waveguides as a χ (2) -based medium [8][9][10][11][12][13] or highly nonlinear fibers (HNLFs) as a χ (3) -based medium [14][15][16][17][18][19]. Recently, a highly efficient χ (3) -based OPA using a silicon nitride waveguide was also proposed [20].…”

The optical parametric amplifier (OPA) has attractive features for optical communications, such as a wideband, high gain, and fast transient response. In addition, by using idler light, which is phase-conjugated light generated in the amplification process, various kinds of optical signal processing, such as fiber-nonlinearity mitigation, wavelength conversion, and phase-sensitive amplification, can be performed. A periodically poled LiNbO3 (PPLN) waveguide is an χ (2) -based optical parametric amplification medium, and it makes both wideband and high-gain amplification possible. We developed a 4-port PPLN module that can combine signal light and pump light into a PPLN waveguide with low loss. In this paper, we overview the applications of OPA to WDM optical fiber transmission and explain the configurations of an OPA using 4-port PPLN modules. As applications of our PPLN-based OPA, we introduce the demonstration of wideband inline amplification exceeding 5 THz. Furthermore, we demonstrate inter-band wavelength conversion between C-and S-bands using PPLN waveguides developed for multi-band optical transmission applications.
