Sebuah esperimen bagi menambah daya pembesaran untuk jalur gelombang panjang (jalur–L) pembesar terdop erbium (PTE) telah didemonstrasi menggunakan reka bentuk yang berbadan dua. Jika dibandingkan dengan pembesar yang berbadan satu, pembesar ini dapat menambah pembesaran untuk isyarat 1580 nm sebanyak 5.5 dB dengan sedikit sahaja penambahan nilai bisingan. Nilai bisingan bertambah sebanyak 0.3 dB kerana kemasukan isolator dalam reka bentuk. Kadar kuasa pam pertama mestilah 33% daripada jumlah keseluruhan kuasa pam untuk nilai optima. Pembesaran maksimum sebanyak 8.3 dB telah diperolehi oleh isyarat 1568 nm semasa kuasa isyarat dan kuasa pam, masing–masing ditetapkan pada 30 dBm dan 92 mW. Keputusan esperimen menunjukkan penggunaan pembesar berbadan dua dapat menjimatkan kos kerana ia menggunakan kuasa pam yang lebih rendah.

Compared to a conventional single–stage amplifier, the small signal gain for a 1580 nm signal can be improved by 5.5 dB without paying much noise figure penalty. The corresponding noise figure penalty was 0.3 dB due to the insertion loss of the optical isolator. The optimum pump power ratio for the first pump was experimentally determined to be 33%. The maximum gain improvement of 8.3 dB was obtained at a signal wavelength of 1568 nm while signal and total pump powers were fixed at –30 dBm and 92 mW, respectively. These results show that the employment of the dual–stage amplifier system will play an important role in the development of a practical L–band EDFA from the perspective of economical usage of pump power.

An experiment on gain enhancement in the long wavelength band erbium doped fiber amplifier (L-band EDFA) is demonstrated. It uses a dual stage technique with dual forward pumping scheme. Compared to a conventional single stage amplifier, the small signal gain for 1580nm signal can be improved by 5.5dB without paying much noise figure penalty. The corresponding noise figure penalty was 0.3dB due to the insertion loss of the optical isolator. The optimum pump power ratio for the first pump is experimentally determined to be 33%. The maximum gain improvement of 8.3dB was obtained at a signal wavelength of 1568nm while signal and total pump powers were fixed at -30dBm and 92mW, respectively. The employment of dual stage amplifier system seems to play an important role in the development of practical L-band EDFA from the perspective of economical usage of pump power.Key Words:  erbium doped fibre; optical amplifier; L-band EDFA; dual stage EDFA; amplified spontaneous emission

AbstractThis paper has simulated the pump laser automatic signal control for erbium-doped fiber amplifier gain, noise figure, and output spectral power. Signal gain and noise figure are deeply studied in relation to laser pump power variations at operating pumping wavelengths of 980 nm and 1,480 nm for previous and proposed models. Similar to the study of the light signal to noise ratio, output power level and maximum Q factor are also simulated versus EDFA amplifier length at pumping power of 500 mW and different pumping wavelength by using the proposed model. The obtained results are better by using a pumping wavelength of 1,480 nm than a pumping wavelength of 980 nm. The optimum EDFA amplifier is 5 m, which gives better performance than other amplifier lengths.
