A Novel Wavelength Division Multiplexing Passive Optical Network Based on Self-Seeding Light Source and Doubling Wavelength-Utilized Rate

摘要

A wavelength-utilized rate-doubled wavelength division multiplexing passive optical network based on a self-seeding light source is proposed. The effect of distributed fiber length and power division ratio on the upstream-signal power is analyzed; the results indicates that raising the power division ratio can increase the upstream-signal power when it is lower than 0.86. The power difference between upstream signals caused by the length difference os distributed fibers is also expanded with power division ratio; thus, the power division ration should be decreased to a proper level to reduce the power difference when the length difference is too large.
