This paper describe a truly-passive coexistence of 10G-PON and GPON compatible reach extension system with a novel optical configuration, by using laser pumps to provide reverse-pumped distributed Raman gain for both 1270nm 10G-PON and 1310nm GPON upstream (US) signals, and using semiconductor optical amplifiers (SOA) as boosters to improve the loss budgets for both 1577nm 10G-PON and 1490nm GPON downstream (DS) signals. The Raman interaction between laser pumps and the two US signals is investigated, and the system transmission penalties of US signals due to Raman ASE noises is measured. The transmission impairments of 1490nm DS signals due to pattern-dependent distortion caused by gain dynamics of the SOA is discussed in this paper. Finally, we present experimental demonstration of coexisting 10G-PON and GPON bi-directional transmission over 50-km of AllWaveTM fiber with entirely passive fiber plant and a total 1:96 split, accommodating link loss budget more than 39-dB for both 10G-PON and GPON US signals.
