1U EDFA Optical Amplifier
The main function of EDFA (Erbium Doped Fiber Amplifier) optical amplifier equipment is to compensate the power of signal light in the transmission link. It can simultaneously amplify optical signals of up to 48 channels (channel spacing is 100GHz) or 96 channels (channel spacing is 50GHz) in the C band. It has the characteristics of flat gain, adjustable gain, and low noise index. It is an indispensable and important part of DWDM system and future high-speed system and all-optical network long-distance transmission.

EDFA amplifier can be divided into: power amplifier, line amplifier, and preamplifier according to the application position;
BA power amplifier: It has the characteristics of high input power, high gain, and high output. It is mainly used at the transmitting end of DWDM system to increase the optical power of DWDM system into fiber;
LA line amplifier: It has the characteristics of low input power, high gain, and high output. It is mainly used between two network nodes of DWDM system to increase the transmission power of DWDM system;
PA pre-amplifier: It has the characteristics of low input power, high gain, and low output. It is mainly used at the end of DWDM system to increase the receiving optical power of DWDM system;
- Standard 19 inches 1U height;
- Supports optical amplification of DWDM systems in the C band;
- Supports optional input amplification with OSC signal;
- Supports power amplification, line amplification (secondary optical amplification), and preamplification;
- Monitors: pump drive current, pump output power, pump switch, pump temperature, input optical power, output optical power, and module temperature;
- Supports adjustable pump switch, AGC mode, and APC mode (input and output optical power are adjustable).
- Supports optical monitoring port (MON).
- LCD display is used to display data very intuitively, which is convenient for users to operate.
