Abstract

We propose a bidirectional coherent ultra-dense time/wavelength division multiplexing passive optical network (UD-TWDM-PON) scheme for 1000 optical network units (ONUs). Then we experimentally demonstrate a bidirectional coherent UD-TWDM-PON using real-time FPGA-based transceivers. The power budget of this system is evaluated based on 1000 downlink ultra-dense wavelength division multiplexing (UD-WDM) channels with 5 GHz channel spacing in C band. The power budgets are 28 dB for DP-QPSK format with 10 Gb/s per user and 30 dB for PS-QPSK format with 7.5 Gb/s per user after 40 km SSMF transmission. The uplink transmission over 40 km SSMF for the 1000 users is also achieved based on 200 channels with 10 Gb/s per channel under channel spacing of 12.5 GHz in L band. Time division multiplexing is performed for the uplink optical signals, where 5 ONUs share one channel in the uplink. The 24-hour real-time performance testing for the bidirectional transmission is also conducted to evaluate the feasibility of the real-time FPGA-based transceivers in the proposed UD-TWDM-PON scheme.
