Dynamic wavelength allocation in wavelength division multiplexing radio-over-fiber access network

Abstract

We demonstrate that dynamic wavelength add-drop multiplexing technology based on a fiber Bragg grating array (FBGA) can be used to improve the efficiency of wavelengths at a burst traffic load for wavelength division multiplexing radio-over-fiber (ROF) access networks. Moreover, we also propose an upstream injection-locked longitudinal mode scheme in a remote node to offer a simple ROF interface. Experimental results demonstrate that these technologies can provide robust and reliable characteristics for large radio terminals.
