Single Channel Erbium-doped Fiber Pre-Amplifier for C-band
Description
The erbium-doped fiber small signal amplifier, also known as a Pre-Amplifier (PA), is specifically engineered for amplifying weak optical signals ranging between -45dBm and -25dBm. It boasts a remarkable typical gain ranging from 35 dB to as high as 45 dB, coupled with a low noise figure to ensure minimal signal degradation.
This pre-amplifier is ideally positioned before the photodetector in optical systems to significantly enhance the detector's sensitivity to weak light signals, thereby improving the overall system's performance and reliability in capturing and processing optical data.
