Paper Abstract

We propose a novel scheme for generation and detection of a 40 Gb/s binary frequency shift keying (FSK) signal. Multispan transmission properties are numerically compared with return-to-zero (RZ) and differential phase shift keying (DPSK) formats. Experimental demonstration shows that a 40 Gb/s FSK signal is transmitted over 50 km standard single-mode fiber (SMF) with 0.8 dB penalty and over 12 dB resilience of span input power, clearly validating the feasibility of this FSK modulation scheme. Transparent wavelength conversion for a 43Gb/s RZ-FSK signal is successfully achieved by FWM in a SOA and in HNDSF. 2R regeneration is also to be purposefully observed in HNDSF which results in limited over-all penalty after 100km transmission link.
