160-Gb/s CWDM capacity upgrade using 2.5-Gb/s rated uncooled directly modulated lasers
01 October 2004
Uncooled 2.5-Gb/s directly modulated lasers are used to demonstrate a coarse wavelength-division-multiplexed (CWDM) transmission capacity of 160 Gb/s. All 16 CWDM channels, modulated at 10 Gb/s, are simultaneously transmitted over 40 km of uncompensated low-water-peak nonzero dispersion fiber. Operation with bit-error ratio BER
