Mo. Vandeventer, POWER PENALTIES DUE TO REFLECTION AND RAYLEIGH BACKSCATTERING IN A SINGLE-FREQUENCY BIDIRECTIONAL COHERENT TRANSMISSION-SYSTEM, IEEE photonics technology letters, 5(7), 1993, pp. 851-854
Crosstalk penalties from a single reflection and Rayleigh backscatteri
ng (RB) are calculated and measured for a bidirectional coherent CPFSK
transmission system, having both transmitters operating at the same o
ptical frequency. A 0.5 dB penalty occurs for -22 dB crosstalk/signal
ratio for both types of crosstalk. The measured crosstalk penalties fo
r RB fit very well with the predicted Gaussian behavior. The crosstalk
penalties for a single reflection are always lower than those for an
equal amount of RB.
