Abstract

This paper evaluates the allowable loss ranges of 1G / 10G dual-rate symmetric long-reach 10 gigabit Ethernet passive optical networks (10G-EPONs) that employ cascaded semiconductor optical amplifiers with fast automatic level controlled circuit (ALC-SOAs) for upstream transmission and a single SOA for downstream transmission. Experiments show that our optical amplifiers have the ability to achieve the maximum loss budget of 61dB with very wide loss ranges for both access and trunk spans; they support up to 80km transmission (60km trunk span and 20km access span).
