| description | The extensive usage of Erbium Doped Fiber Amplifier (EDFA) in fiber optic networks creates many
new configurations and technologies. Conventional optical amplifiers based on EDFA can amplify
multiple channels at the same time, but within a single fiber optic core. The amplifier can be made to
support multiple fibers, however the channels must be at different set of wavelengths, which is
impractical since optical channels are standardized at a specific set of wavelengths. Therefore, the
application of optical amplifiers are limited for one fiber core only. As an alternative, a design of an
EDFA is hereby proposed. With this amplifier, it will make the network management simpler. It also
provides flexibility in optical network design.
In this dissertation, the design and development of EDFA is detailed and discussed. The design has
made it possible to support two fibers with each one carrying the same set of wavelengths. This is
achieved by taking advantage the polarization multiplexing techniques which allow a combination of lights by setting them linear and orthogonally apart. The signals co-exist in a single core EDF by
differentiating both of their polarity using polarization controllers. Then it will combine through in a
single core using a 3dB coupler. The combined signals are then amplified by the EDFA
simultaneously, doubling the amount of signals carried by the same wavelength.
The amplifier has been successfully tested at the transmission speed as high as 2.5Gbps. Moderate
gain and noise figure of the EDFA was achieved at an optimum pump power for the EDF at 40mW.
The transmission performance also shows tolerable polarization crosstalk due to unpolarized amplified
spontaneous emission with the bit error rate showing little difference compared to that of the
conventional amplifier. The results were obtained mainly through experimentation while others are
through software simulation. |
