There is no specific part number for this item.
This is specifically designed for 30dB of gain at 1550 nm. This typf of amplifier is commonly used in fiber optic
communication systems to boost signal strength.
It works by using erbium-doped fiber to amplify light signals within the 1500nm wavelength range, which is a common wavelength used in telecommunications.
The 30 “dB gain” means the amplifier increases the optical power of the input signal by a factor of 1000 (since 10*log (power_out/power_in) = 30dB =>power_out/power_in = 10 ^3 = 1000).
The amplifier has input and output ports, an on/off switch, and a current control.
It also includes a warning label about the invisible laser radiation emitted from the aperture
