This paper presents a new long reach PON (LR-PON) scenario operating at a single carrier of 40-Gbit/s for downstream, as an upgrade option of the LR-PON evolutionary strategy. An electrical 3-level duobinary modulation format was proposed for the 40-Gbit/s downstream transmission. In this paper the required optical signal to noise ratio (OSNR) and optical power budget were investigated based on analytic...
All-optical FDM grid generation and channel selection is experimentally demonstrated through optical signal processing. Full-duplex 10G/2×10G transmission with reflective ONUs is validated for 20dB budget and 25km reach. An optional 10Gb/s FDM/TDM mode is verified.
The paper gives an overview of burst-mode receiver developments. The receiver design challenges associated with high speed TDMA PONs are discussed and recent results of 10Gb/s burst-mode receivers are highlighted.
