Abstract
This paper reports the world's first field trial of a 100-km reach symmetric-rate
ten gigabit Ethernet passive optical network (10G-EPON) system that uses
optical-amplifier-based PON repeaters. Semiconductor optical amplifiers (SOAs) are
utilized to handle the 10G-EPON wavelength allocation defined in IEEE802.3av; a fast
automatic level control technique is applied to cascaded SOAs for upstream amplification
to achieve high gain and wide input dynamic range. An electronic dispersion compensation
technique is also applied for downstream detection. These techniques support a 79.5-dB
loss budget and 100-km reach transmission with 40 km span lengths. In a field trial, we
successfully demonstrate bidirectional real-time uncompressed high-definition television
signal transmission over installed standard single-mode fiber links.
