An ultra-dense 100 Gb/s multi-band orthogonal frequency division multiplexing (MB-OFDM) system employing
virtual-carrier assisted direct-detection and a 2.85 GHz receiver bandwidth is demonstrated experimentally. Nine OFDM bands with band spacing of 6 GHz and a band capacity of 11 Gb/s are employed. The proposed system enables single-band extraction with low-complexity, provides high granularity, flexibility and scalability, and is proposed for metropolitan (metro) networks.
The experiments show that the transmission of the 100 Gb/s
MB-OFDM signal comprising the 9-bands along metro networks reaching 150 km is successfully accomplished with bit error ratio levels below the FEC threshold. Reduced penalty relative to back-to-back operation is observed for optical power levels launched into each fiber span in the range between 0 dBm and 4 dBm.
