2R regenerator based on a 2-m-long highly nonlinear bismuth oxide fiber
Abstract:
We report the use of a 2-m-long Bismuth Oxide fiber with an ultra-high nonlinearity of ~1100 W(-1)km(-1) in a simple 2R regeneration experiment based on self phase modulation and offset filtering. Numerical simulations and experimental results confirm the suitability of this kind of fiber for 2R regeneration. An improvement in receiver sensitivity of more than 5 dB at 10 Gb/s and 2 dB at 40 Gb/s is achieved.
