Intraband crosstalk induced by back reflections, mainly Rayleigh backscatte
ring is experimentally and theoretically studied in a bidirectional system
using the same wavelength. Assuming that 1.0 dB of power penalty is an acce
ptable design criterion, the distance between the adjacent nodes is limited
to be 40 km. The derived crosstalk penalties are in excellent agreement wi
th those obtained from experiments. (C) 2001 Published by Elsevier Science
