Abstract

This letter numerically analyzes and experimentally confirms by PCVD process a large effective area single-mode optical fiber.Its effective area is as high as 133μm2 with its attenuation coefficient optimized to 0.183dB/km and its bending loss to 0.45dB/turn at 7.5mm bending radius at 1 550 nm by using a trench structure.Furthermore

it verifies the propagation performances of the 100Gbit/s and 400Gbit/s systems such as BER and Qfactor with dual polarization DFT-S CO-OFDM4QAM/16 QAM modulated signals.The results show that this fiber effectively improves the optimum incident power and the nonlinear effects and extends the propagation distance by 30% and that can effectively optimizes the 400Gbit/s transmission system and has broad prospects of applications in FTTx.
