A 40 Gb/s IM payload/2.5 Gb/s header AOLS technique based on an all fiber realization

An all fiber IM/FSK coding technique for the realization of the 2.5 Gb/s NRZ label swapping onto a 40 Gb/s NRZ payload signal has been numerically studied in this work. Four wave mixing (FWM) and cross phase modulation (XPM) on a dispersion shifted fiber (DSF) are used, for the combination of the Intensity modulated (IM) payload with Frequency Shift Keying (FSK) modulated header synchronously on the same optical carrier, and for the header removal and payload wavelength conversion respectively. Simulations have proven the feasibility of this DSF fiber based method, and shown the potential for high bit rate AOLS applications.
