EDFA - Erbium Doped Fiber Amplifier
Product Overview
This EDFA amplifier by HYD Technology is an optical module f designed to amplify the signals in an optical fiber to ensure communication over longer distances using dispersion devices. It comprises a very reliable pump laser and has an ATC circuit and ACC circuit, which allows it to provide a reliable and stable output power.
It comprises a GFF, which is professionally designed, and it combines with an optical path, which eliminates the noise and flatness in the optical fiber link. This device also leads to achieving the APC and AGC functions.
- This module supports DWDM c-band amplification for optical signals.
- Offers a maximum output starting power of more than 23dB and a minimum negative of 35dB.
- Supports the signal amplification with optional OSC.
- Line amplification, power amplification, and pre-amplification are supported.
- It carries out monitoring pimp output power, pump driver current, and pump temperature.
- Provides support to AGC mode, sets pump switch, and APC mode.
- Offers support to multiple network management modules like SNMP unified module, WEB, and CLI. Moreover, it also supports optical monitoring ports.

Application 1:
A Power Amplifier can be used along with the multiplexer so that the power of different wavelength signals can be increased once they are multiplexed and transmitted. The signal’s power after multiplexing is large, and gain requirements followed by noise figures might be low. However, once the amplification is done, the output power needed is quite large.
Application 2:
Line amplification is carried out once the power amplification has taken place; this helps compensate for the loss of the transmission line and needs very small noise figures with a huge amount of optical power output.
Application 3:
Before the demultiplexer is applied, the preamplifier is used. This helps amplify the signal and improve the receiver’s sensitivity in the signal-to-noise ratio context. A massive input of power can lead to suppressing the receiver’s noise. The noise figure, in this case, is too small and hence doesn’t require much power for the output.
