C-Band Gain DWDM Fiber Amplifier
FWA-1550G DWDM EDFA (Erbium Doped Fiber Amplifier) is a C-band flat gain optical fiber pre-amplifier, which is mainly installed in front of the receiving device. Ultra-low optical power input: -30 ～ -15dBm, gain is fixed 10 ～ 30dB output to improve the sensitivity of transmitting and receiving equipment and achieve the purpose of extending the signal for long-haul transmission.
FWA-1550G series gain fiber pre-amplifier uses advanced electronic control technology and complete software functions. By optimizing the optical path, it has a wide operating wavelength range, low noise, and excellent gain flatness characteristics.
【Application】（1） Line amplify （2） Power amplify （3） Optical distribution system （4） SFP, SDH, ATM long-haul transmission （5） Video, Ethernet optical transmission system
◆ With excellent optical performance, advanced electronic control technology and complete software functions, the system can obtain excellent CNR by optimizing the optical path and minimizing the NF of EDFA.
◆ Reliability: Adopt 19" 1U standard chassis, built-in high performance modular dual switching power supply, can work in AC 85 ～ 265V city network voltage. DC 48V power supply option is available as well. Dual hot and reserved power supply with Chassis automatic heat dissipation control.
◆ Intuitive: The pump laser is the most expensive component. The built-in microprocessor monitors the working status of the pump laser, and the working parameters are displayed on LCD.
◆ Network management Interface: Web transponder is line with the national standard and compatible with the SCTE HMS standard, achieving WEB monitoring function.
◆ The working wavelength is C band, which meets the communication technology requirements of DWDM systems.
◆ Excellent gain flatness (GF <1.0dB) makes the optical power gain of each channel flat.
