High Transmitted Bit Rate Through Graded Index Polymer Optical Fibers: The Worst Case

摘要

In the present paper, polymer optical fibers in high speed optical communication systems are deeply studied over wide ranges of the affecting parameters. The phenomenon of Four-Wave Mixing is reduced via the increase of channel spacing. Two multiplexing methods are applied , ultra—wide space division multiplexing (UW-SDM) and ultra-wide wavelength division multiplexing (UW-WDM) , where 1200 channels are processed to handle the product of bit rate and repeater spacing for cables of multi-links (12-120 links/core). Two transmission techniques are investigated namely soliton and maximum time division multiplexing (MTDM).The product (either per link or per channel) are treated over wide ranges of the affecting parameters. The worst real case of power budget and the total time spreading due to the effect of transmitter, optical link, and receiver are deeply investigated over wide ranges of affecting parameters. Dispersion, attenuation ,and repeater spacing are deeply studied to handle average worst bit rate, and average worst product either per link or per channel over the wavelength range (1.45 μm-1.65 μm) with Raman amplification technique. This is done through two bandwidths, the worst bandwidth and the normal one.
