Answer: The EDFA is an Optical amplifier allowing 1550nm wavelength to be
optically amplified. Amplification varies from 10- 30db, loss in fiber is usually 0.25db/km. What is your application? What transmitter do you use? What is the optical distance you need to send the signal? Please answer and we will determine which EDFA you need.
El PA EDFA se utilizan antes de la óptica del receptor para amplificar la se?al óptica DWDM y aumentar el presupuesto óptico y la distancia de transmisión en fibra.
