Z. Bakonyi et al., 10Gbit/s RZ transmission over 5000 km with gain-clamped semiconductor optical amplifiers and saturable absorbers, ELECTR LETT, 36(21), 2000, pp. 1790-1791
By combining a gain-clamped semiconductor optical amplifier (GC-SOA) and a
saturable absorber-semiconductor optical amplifier module, 10Gbit/s RZ tran
smission over 5000km (200 x 25km) has been demonstrated in a fibre loop set
up. It is shown that a GC-SOA could compensate for the patterning introduce
d by a conventional SOA.
