Hi Karan Ahuja,
Are you mean Optical Amplifier to SOA (semiconductor optical amplifier) or other.
Although i want to discuss the difference among all others amplifiers to EDFA.
Here is EDFA specifications
• Gain of about 40dB or greater
• Wavelength in the range from 1530 nm to 1560 nm
• Maximum saturation of about 22 dBm
• Noise figure in the order of 5dB
• Pump power of about about 25 dBm
• bandwidth (3dB) – 30 to 60
• Polarization sensitivity not available with EDFA
EDFAs will provide high pump utilization of power and is used along with optical filters to equalize the gain response. There are so many merits of EDFA but as they are not small, they can not be seamlessly integrated with other semiconductor devices in the chain.
Thanks,
