| Summary: | Various aspects concerning Erbium Doped Fiber Amplifiers (EDFA) for use in C-band
transmission system were investigated through experimental work culminating in the
design and implementation of three different C-band EDFA’s. The most promising being
an EDFA utilizing double pass with tunable bandpass filter (TBF) amplification scheme.
The configuration is a new approach to increase the sensitivity of the preamplifier before
the signal is received by the receiver. This is because, limited sensitivity preamplifiers
offered in the markets that limit the fiber optic link design. Thus, a new approach is
desirable in solving the problem. In this thesis, new technique is proposed to increase the
sensitivity up to 10dB.
STM-1 and STM-4 Bit Error Rate (BER) test on SDH network was successfully
conducted in a laboratory environment. The test showed that no error was introduced.
Finally it is concluded that DPEDFA is reliable to be used as a device to realize high
sensitivity preamplifier, as its realization would result in a huge increase in additional
power budget with minimum installation and maintenance complexity and cost. |
