Abstract:

we give an account of a wavelength division multiplexed-orthogonal frequency division multiplexed-passive optical net-work (WDM-OFDMPON), using a tunable mode bolted brush source for downstream transmission. The 10 brush tones are separated by 10GHz and modulated by 12.75 GB/s compatible single side band (SSB) OFDM signal. Transmission over 50 km and 87 km of standard single mode fiber was successfully demonstrated. The average spectral efficiency of 1.12 and 1 bit/s/Hz were obtained in conjunction with the use of low complexity electronics. Relative to the back-to-back case the penalties after transmission over 50km were 1dB at a bit error rate (BER) of of 3 × 10−3 this indicates improved efficiency in transmission. All channels after 87km transmission achieved performance below the 20% forward error correction (FEC) limit.
