1426nm/1440nm/1455nm 拉曼放大器
Raman Amplifier Benchtop Units are designed for distributed Raman amplification in both the C-Band and L-Band. Each pump channel is configured with two high power pump laser diodes and one polarization beam combiner (PBC). Utilizing 100% Telcordia-qualified components, the unit incorporates micro-controller based laser current and TEC control circuitry for ehanced stability and reliability. It is an ideal instrument for 10G/40G transmission and fiber sensors systems.
