32 Port 1550nm High Power EDFA for CATV

Description

1550nm EDFA Features

High quality: The front stage pump uses 980nm as a small signal amplification, and a dedicated pulse width constant temperature cooling chip. The back stage uses imported high-power multi-mode pumps, and the power is precisely controlled by hardware circuit APC, AGC, and the dual pump hot backup design minimizes the NF of HPEDFA, which is comparable to conventional EDFA. The system can obtain excellent CNR.
Flexibility: The output optical power is adjustable. The adjustable range of the output optical power (-3~-6dB) is required when the user orders. Multiple ports with low power and reasonable output power distribution. The internal 1310/1490/1550nm EPON and GPON splitters can also be integrated, which greatly facilitates the application of EPON networks.
Intuitive: The machine has a built-in microprocessor to monitor the working status of the pump laser, and the working parameters are displayed on the panel LCD window.
Network management type: The optional status monitoring transponder ensures that it meets the national standard and is compatible with the SCTE HMS standard, and can realize the network management monitoring function.
Power plug-in type: The aluminum type plug-in switching power supply is used, which is conducive to heat dissipation and replacement. And dual power supply hot and cold backup.
Intelligent pump over-temperature protection function, when the pump temperature exceeds 50℃, the pump is automatically turned off. When the temperature is below 50℃, the pump is automatically turned on.
