“…Use of more than one pump laser diode can solve this problem. Among the several schemes available for pumping EDFAs, the best configuration to offer the highest output power and relatively low noise figure is the bidirectional pumping scheme [4][5][6][7][8][9][10]. In this configuration, the signal to be amplified is launched from one end of the amplifier fibre and the pump power is launched from both the ends of the fibre.…”

We have evaluated the performances of bidirectional optical amplifiers which were suited for the costeffective implementation of amplified bidirectional passive optical networks (PONs). First, we measured the maximum gains of two simple bidirectional optical amplifiers implemented without using any optical components for the suppression of reflected signals. From the results, the maximum gains of two simple bidirectional amplifiers with a broadband light source (BLS) seeded optical source were limited to be 27 dB due to the reflection-induced in-band crosstalk, when the reflectance coefficients were measured to be -33 dB in both directions. Then, we have also implemented a bidirectional optical amplifier with two band splitters for the amplified bidirectional PON where the two different wavelength bands were allocated to the downstream and upstream signals transmission. In our measurement, we confirmed that the maximum gain of bidirectional optical amplifier with two band splitters could be increased to more than 30 dB owing to the efficient suppression of in-band crosstalk.
