Abstract :
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<1E-9 is demonstrated for all 16 channels from room temperature to at least 65°C.
