A mobile fronthaul approach that can facilitate 96 channels of 20MHz 64QAM LTE formatted signals over 20km fibre has been demonstrated for the first time, due to centralized pre-compensation for downlink and post-compensation for uplink in BBU, RRH sustains neat.
We propose and experimentally demonstrate a new orthogonal frequency division multiple access-based passive optical network (OFDMA-PON) architecture supporting flexible all-optical virtual private network (VPN) with source-free optical network units (ONUs). In our scheme, variable-bit-rate VPN communications are achieved. Moreover, based on optical sideband reuse at the ONU side and optical carrier...
