Abstract

Optical orthogonal frequency division multiplex (OFDM) symbol generation by all-optical discrete Fourier transform (DFT) is proposed and investigated for 100-Gbps transmission performance. We discuss a design example for a 4 × 25Gbps OFDM transmission system and its performance comparison with that for a 100-Gbps single-channel return-to-zero data transmission in an optically amplified system.

A schematic circuit diagram of 4 × 25Gbps all-optical OFDM transmission system. Solid and dotted lines show optical and electrical connections, respectively. The fiber link consists of 80-km SMF-28 fibers and optical amplifiers with full dispersion compensation for the fiber links by dispersion compensation modules (DCM). Fiber spans are varied from 1 to 5 to change the OSNR at the receiver. Span input power of an OFDM channel is 0 dBm. The amplifier gain and noise margin are 20 dB and 6 dB, respectively.
