“…Transmitted optical power (TOP) could be increased to achieve the required link power budget. An electro absorption modulated laser (EML) boosted by an external semiconductor optical amplifier (SOA) can be placed at the TX side to increase launch power in PONs for a wide wavelength range of 1200-1650 nm [26]. For a 50G PON, EML + SOA was exploited DS to support high budget classes.…”

In this paper we present the simulative analysis of a 200 Gbps per wavelength (λ) 8-level pulse amplitude modulation (PAM-8) downstream communication over up to 20 km single mode fiber (SMF) in C-band based on direct detection (DD) achieving at least a 29 dB link power budget in a PON environment. We use chromatic dispersion digital pre-compensation (CD-DPC) and a dual-arm in-phase and quadrature Mach–Zehnder modulator (IQ-MZM) at the optical line termination (OLT) side, while preserving DD in the optical network unit (ONU). Three receiver digital-signal-processing (DSP) options are analyzed and compared: square-root-like technique (SQRT) in combination with a feed forward equalizer (FFE) and a decision feedback equalizer (DFE), the Volterra nonlinear equalizer (VNLE), and the SQRT in combination with the VNLE. The SQRT can be applied in combination with the VNLE to decrease the receiver DSP complexity while maintaining the required system performance. We show that PAM-8 with CD-DPC and the SQRT in combination with the VNLE is a feasible solution for 200 Gbps per λ downstream C-band transmission for PON.

“…In order to reduce the deployment and the operation costs, the use of optical amplifier to extend reach and splitting ratio in future PON systems are discussed [1]. Among the proposed solutions, semiconductor optical amplifiers (SOA) appear to be efficient and cost-effective for multiple-wavelength networks [2]. The use of a single SOA for budget extension of coexisting gigabit-capable PON (G-PON) and 10-gigabit-capable PON (XG-PON) was demonstrated [3].…”

“…Among the proposed ones are the midway amplifiers (Fig. 1b), such as EDFA [6] and semiconductor optical amplifiers (SOA) [7][8][9], Raman amplification [10,11], and nonamplifier based coherent detection [12] techniques. For example, the use of a single SOA for optical budget increase of coexisting gigabit-capable PON (G-PON) and 10-gigabit-capable PON (XG-PON) is shown in [9].…”

Saturated Collision Amplifier (SCA) is a novel amplification scheme that uses SOA saturation in order to maximize the output power and minimize the ASE noise and the polarization sensitivity. We demonstrate the SCA reach extension in a commercial single-wavelength XGPON1 prototype system where bidirectional optical budget of up to 50 dB is obtained. The traffic performances are compared between the SCA and the conventional SOA extender. The novel extension scheme is demonstrated also for two- and four-wavelength 10 Gbit/s unidirectional downstream configurations with 45 km and 100 km transmission distances with 58-dB maximum total optical budget for each wavelength.
