Abstract

A novel secure wavelength hopping passive optical network (WH-PON) is presented in which physical layer security is introduced to the access network. The WH-PON design uses a pair of matched tunable lasers in the optical line terminal to create a time division multiplexed signal in which each data frame is transmitted at a unique wavelength. The transmission results for a 32-channel WH-PON operating at a data rate of 2.5 Gb/s are presented in this paper. The inherent security of the WH-PON design is verified through an attempted cross-channel eavesdropping attempt at an optical network unit. The results presented verify that the WH-PON provides secure broadband service in the access network.
