Record transmissions with the direct modulation of a 1550nm-hybrid III/V-on-Silicon laser of 21.5Gbps in optical back-to-back (B2B) and 12.4Gbps over 50km of Single-Mode Fiber (SMF) are achieved. Neither optical amplification, nor optical dispersion-compensation is used.
We present a detailed performance investigation of self-seeded RSOAs in WDM-PONs. The influences of several system parameters on the transmission performance are examined, including signal extinction ratio, stable seeding power, and features of the wavelength multiplexer.
