|July 16, 2021
Summary
A polarization insensitive fiber optic parametric amplifier (PI-FOPA) significantly outperforms discrete Raman amplifiers (DRA) and erbium-doped fiber amplifiers (EDFA) in long-reach optical access networks. PI-FOPA enables higher traffic density and power budgets for bursty 10 Gbps signals.
Area of Science:
- Optical Communications
- Fiber Optic Amplification
- Network Performance Analysis
Background:
- Long-reach optical access networks face challenges with bursty traffic and limited power budgets.
- Traditional amplifiers like EDFA and DRA have performance limitations in such scenarios.
Purpose of the Study:
- To compare the performance of a PI-FOPA against EDFA and DRA in a 50 km optical access network.
- To evaluate amplifier capabilities under varying traffic densities (5%-97%) for 10 Gbps bursty signals.
Main Methods:
- Experimental comparison of PI-FOPA, EDFA, and DRA in a 50 km fiber link.
- Transmission of 10 Gbps bursty signals with traffic densities from 5% to 97%.
- Analysis of power budget requirements for each amplifier type at different traffic densities.
Main Results:
- PI-FOPA supports up to 97% traffic density, significantly higher than DRA (30%) and EDFA (15%) at the same power budget.
- PI-FOPA offers a 3 dB (vs. DRA) and 5 dB (vs. EDFA) higher power budget for 75% traffic density.
Conclusions:
- PI-FOPA demonstrates superior performance for handling high-density, bursty traffic in long-reach optical access networks.
- PI-FOPA presents a viable solution for enhancing network capacity and power efficiency compared to conventional amplifiers.
