Paper Abstract

The authors propose a novel architecture of passive optical network (PON), which consists of time division multiplexing (TDM) based downstream (10  Gbit/s) and quasi-synchronization (Q-S) electrical code division multiplexing access (ECDMA) based upstream (2.5  Gchip/s), and realize the prototype of this TDM-ECDMA PON. The high speed (2.5  Gchip/s) all digital en/decoding of upstream have been achieved by field-programmable gate array in this prototype. The frames error rate (FER) free transmission of Q-S ECDMA based upstream is demonstrated after 20 km fiber link. Then receiver sensitivity of optical line terminal in upstream transmission can be improved ∼ 6  dB by coding gain compared with traditional 2.5  Gbit/s TDM PON.
