Wavelength Division Multiplexing at 2μm

Abstract

This paper shows, for the first time, the implementation of a WDM subsystem at the 2µm wavelength window with mixed formats. Three wavelength channels were directly modulated with BPSK Fast-OFDM at 5Gbit/s per channel, with a fourth channel NRZ-OOK externally modulated at 8.5Gbit/s giving a total capacity in excess of 20 Gbit/s.
