5-Gb/s upstream transmission using an RSOA seeded by ultra-narrow spectrum-sliced incoherent light
A 5.35-Gb/s upstream transmission using an ultra-narrow spectrum-sliced incoherent light source and an RSOA is demonstrated. Transmitter de-emphasis is used to compensate for the bandwidth limitation of reflective semiconductor optical amplifier. Offset optical filtering technique is exploited to mitigate the excess intensity noise in the spectrum-sliced light source.
