Multiple Virtual Private Networks Over Passive Optical Networks Using RF Subcarrier Multiplexing and Fabry–PÉrot Laser Diodes

摘要

An optical layer solution for implementing multiple virtual private networking capabilities over a passive optical network using subcarrier multiplexed (SCM) transmission is proposed and experimentally demonstrated with 60-Mb/s data multiplexed with two radio-frequency subcarriers. The transmission of the SCM data is carried out using Fabry–PÉrot laser diodes. Experimental results and theoretical analysis show that our technique can potentially support high data rate traffic from a large number of simultaneous virtual private networks with minimal penalty resulting from optical beat interference.
