Erbium Doped Fiber Amplifier Module Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-13255
Indian Lab Suppliers supplies the Erbium Doped Fiber Amplifier Module (Product ID: 13255) as part of its electronics engineering lab equipment range. It is a C-band erbium-doped fibre amplifier (EDFA) trainer in which a 980 nm pump laser amplifies a 1550 nm signal inside erbium-doped fibre.
Quick Answer
A 980/1550 nm WDM combines the pump and the signal into the erbium-doped fibre. The pump raises Er3+ ions to an excited level, from which they relax to a metastable level; the 1550 nm signal then triggers stimulated emission and is amplified across the C band (1530–1565 nm). Students measure small-signal and large-signal gain, compare forward and backward pumping, and use a 2 nm filter at 1550 nm and a 0.8–60 dB variable attenuator to set input levels, with an InGaAs PIN detector reading the output. PC software over USB 2.0 controls both lasers, plots V-I curves and applies internal modulation at 100 Hz, 200 Hz, 500 Hz or 1 kHz. The 980 nm pump delivers up to 100/150 mW of invisible light: never look into a connector or fibre end, and keep ends capped when the pump is on.
