10-Gbps WDM-PON with RSOA-based colorless ONUs and MZI-based optical equalizers

Proposed in this paper is a 10-Gbps uplink transmission over 25-km fiber in WDM-PON, in which band-limited RSOAs are applied to colorless ONUs and cascaded Mach-Zehnder Interferometers are used as three-tap optical equalizers in OLT.
