Abstract
The behavior of a 2R optical regenerator in a link limited
by amplified spontaneous emission (ASE) noise and polarization-mode
dispersion (PMD) is investigated in detail in this paper. 2R regeneration techniques are well
known for combating the accumulation ASE noise in an optical signal, but
their behavior in the presence of PMD is mostly unknown. Here, we propose a
general method to calculate the total outage probability in a link including
a cascade of optical regenerators. Through the use of semianalytical models,
we study the ability of 2R optical regenerators to combat at the
same time PMD distortions and ASE noise accumulation in an optical signal,
and show their interesting potential to counter independently both
detrimental effects.
