Application Scope of Raman 1550nm optical Fiber Amplifier: Applied in span of above 90km (e. G. 90-160km, even 200km).

Features of Raman 1550nm optical Fiber Amplifier:
1. Even number(number of pumps is 2468)pump design ensures stability and reliability of gain flatness.
2. Adopt specialized pump laser. Each wavelength is fixed in the scale. (1425-1445nm)
3. Very low effective noise coefficient (-2dB, typical value) greatly increases CNR index.
4. Pump polarization insensitivity design of PBC (polarization beam coupling) can ensures gain stability.
5. 1U has local allocation (passed RS-232) and function and system of remote network management RJ45 which meets national standard.
6. Network management software is provided by random.
