F. Liu et al., Chirped return-to-zero source used in 8 x 10Gbit/s transmission over 2000 km of standard singlemode fibre, ELECTR LETT, 36(16), 2000, pp. 1399-1400
A new and simple chirped return-to-zero transmitter is proposed and success
fully used in 8 x 10Gbit/s transmission over 2000km of standard singlemode
fibre with 80km amplifier span.
