Overview: The Erbium-Doped Fiber Amplifier is a high power optical amplifier. It offers a highly reliable, flexible and low-cost solution for CATV large area coverage of metropolises and medium sized cities, that are high density home pass, especially for FTTH application.The EDFA can work with BAUDCOM or Huawei GPON OLT together, working as total solution.

• Feature:
• High output power, E-Y co-doped
• Warm backup, on-line standby, auto redundancy
• Support ITU channels banding
• Low optical input power, Adjustable output optical power -3dB
• APC / ATC circuit design, built-in high-power optical isolator, mainly used for fiber access network of EPON architecture
• Single/dual input for choice, built in optical switch for dual input, the switching  power can be set by the button in the front panel or by web snmp.
•  Output adjustable by buttons in the front panel or web snmp, the range  is +0.5dBm～-4.0dBm
