Abstract

Capacity demand has continued to increase exponentially. For the system capacity expansion, increasing the spectral efficiency by using multi-level modulation formats may be a good candidate. One drawback of multi-level formats is the requirement of higher signal-to-noise ratio. This requests more frequent OEO regenerations due to its shorter reach. Optical regeneration using phase sensitive amplifier (PSA) has a possibility to prolong the reach by suppressing phase noise generated through fiber transmission. In this paper, we discuss a network architecture having optical restoration process, and its advantages and merits. Then, we show proposed PSA and optical restoration schemes and their system tolerance against chromatic dispersion.
