WDM-PON network upscaling using in-building linear SOAs

Abstract

In this work we propose a WDM PON migration from FTTB to FTTH access by employing bidirectional amplification by a linearized semiconductor optical amplifier. We demonstrate that a semiconductor optical amplifier placed at the entry of a group of ONUs sharing the same wavelength can boost the loss budget allowing to compensate for the losses of a passive splitter up to 1:16 division rate, allowing to upgrade existing WDM PONs FTTB structures to permit the fiber to reach the final user's home.

Design & Analysis of Noise-Resilient Mix Data Rate Passive Optical Network Supporting Simultaneous Transmission of Both NGPON Standards

“…Due to low cost point-to-multi point design with high data rate, high quality and modern services supporting features, passive optical network (PON) is become most promising candidate in next generation access networks. Till now, several standards of PON have been introduced by ITU-T and IEEE such as ATM-PON (APON), Broadband-PON (BPON), Gigabit-PON (GPON), Extended GPON (XGPON), and Next Generation-PON 1(NG-PON 1) and the recent Next Generation-PON 2 (NG-PON 2) have been introduced [3][4][5] To achieve high data rate transmission, several advanced modulation formats have been proposed such as DQPSK with IRZ [6], RZ-DQPSK with On-Off keying (OOK) [7], Carrier suppressed RZ CSRZ-QDPSK [8], RZ-DQPSK with dispersion compensated fiber (DCF) [9], three different Differential Phase Shift Keying (DPSK) techniques and the WDM PON with semiconductor optical amplifier (SOA) [11]. But these techniques are either low data rate supported or single standard transmission based i.e.…”
