U. Gliese et al., CHROMATIC DISPERSION IN FIBEROPTIC MICROWAVE AND MILLIMETER-WAVE LINKS, IEEE transactions on microwave theory and techniques, 44(10), 1996, pp. 1716-1724
The influence of chromatic fiber-dispersion on the transmission distan
ce of fiber-optic microwave and millimeterwave links is analyzed and d
iscussed in this paper, it is shown that dispersion significantly limi
ts the transmission distance in intensity modulated direct detection l
inks operating in the above 20 GHz frequency region by inducing a carr
ier to noise penalty on the transmitted signal, At 60 GHz, a 1 dB pena
lty is induced after less than 500 m transmission over standard single
-mode fiber with a dispersion of 17 ps/km . nm and the signal is compl
etely extinct after 1 km, In remote heterodyne detection links, the di
spersion induces both a carrier to noise penalty and a phase noise inc
rease on the transmitted signal, It is shown, however, that the induce
d carrier to noise penalty is insignificant, At 60 GHz, the induced pe
nalty is less than 0.3 dB after 100 km transmission. The phase noise i
ncrease proves more dominant. At 60 GHz, a 150 Mbit/s QPSK signal is l
imited to around 10 km of transmission.
