Abstract

With the ever-increasing bandwidth demand of the end-customers, the 100-Gb/s access solution has attracted more and more attention. In this letter, we propose a symmetric 100-Gb/s digital signal processing-enhanced time wavelength division multiplexed passive optical networ (TWDM-PON) architecture with four pairs of wavelengths. A 4 × 25 -Gb/s TWDM-PON is experimentally demonstrated over a 26.7-km fiber using double sideband (DSB) orthogonal frequency division multiplexing (OFDM) modulation. The reflective semiconductor optical amplifier is deployed in the optical network unit (ONU) to enhance the receiver sensitivity of downstream OFDM signals, and DSB single-carrier frequency domain equalization modulation is used for upstream transmission to reduce the complexity and cost of the ONU.
