This paper proposes a novel bandwidth-elastic and energy-efficient passive optical network (PON) based on the coherent interleaved frequency division multiple access (IFDMA) scheme. We experimentally demonstrate the coherent IFDMA-PON uplink transmission up-to 30 Gbps over a 30 km standard single-mode fiber with 2 × optical network units (ONUs). A low-complexity digital carrier synchronization technique enables multiple access of the ONUs on the basis of 78.1 MHz narrow band orthogonal subcarriers without any guard-bands.
本文提出了一种基于相干交织频分多址（IFDMA）方案的新型带宽弹性且节能的无源光网络（PON）。我们通过实验证明了相干IFDMA-PON上行链路在30 km标准单模光纤上，通过2个光网络单元（ONU）实现高达30 Gbps的传输。一种低复杂度的数字载波同步技术使得ONU能够基于78.1 MHz窄带正交子载波进行多址接入，且无需任何保护带。
