DRA5228/F
C-Band Separate Dispersion Compensation Fiber Raman AmplifierProduct DescriptionAITC DRA5228/F is a separated optical fiber Raman Amplifier. It adopts built-in negative dispersion DCF as gain medium. In the system, it can realize the concentration amplification of the optical signal. It's especially suitable for over-long trunk that needs high dispersion compensation.
Product features1.Low noise figure and flat gain.
2.High negative-dispersion figure
3.High dispersion compensation
4.High switch gain.
5.Perfect laser APC, AGC, ATC closed-looped circuit ensuring long life and stable operation of the pump laser.
6.Adopts famous Fitel Raman pump laser.
7.Different gain suits for different network.
Main application1.Extra-long trunk that needs high dispersion compensation.
2.Fiber CATV system, extra-long trunk that is inconvenient for building relay station.
Relay distance > 60Km.
Single span distance > 80Km.
3.DWDM, CATV extra-long trunk optical transmission system.
4.Submarine optical transmission system.
