We present two gigabit/s spectral-amplitude-coding O-CDMA techniques that use coherent multi-frequency light. The techniques achieve high beat-noise tolerance by either employing multi-frequency self-homodyne detection or using spectral M-ary ASK based on electrical-domain spatial-code spreading.

We propose an adaptive quasi-cyclic LDPC-coded multilevel modulation scheme, suitable for use in future 100 Gb/s and 1 Tb/s Ethernet technologies. In proposed scheme, the codeword length and column-weight of a parity-check matrix H are kept constant while the code-rate adaptation is performed by varying the row-weight and permutation-block size of H.

Optical OFDM's high PAPR values limit the systems nonlinear tolerance (NLT). A 2.6-dB improvement in NLT has been found by peak clipping. Towards higher bit rates above 50 Gb/s, we observe an additional NLT increase of 8 dB per 10x increase in signal bit rate.
