The Oprel OFA20D-22111S is an Erbium Doped Fiber Amplifier (EDFA) designed for long-haul optical communication systems operating in the C-band. It amplifies 1550 nm signals across the 1530 nm to 1565 nm wavelength range, extending transmission distances and improving signal integrity in telecommunications, CATV, and research applications. The unit accepts input power from -10 dBm to +10 dBm and delivers typical output power of +20 dBm with adjustable optical gain up to 25 dB. A noise figure of ≤5 dB and SNR exceeding 30 dB ensure minimal signal degradation. Polarization dependent loss remains ≤0.5 dB typical, while optical return loss reaches ≥50 dB for system stability.
