1462nm/1490nm 拉曼放大器 機架式
Raman Amplifier Rackmount 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). Powered by single 5VDC supply, the unit includes micro-controller based laser current and TEC control circuitry for ehanced stability and reliability. It is an ideal building block for 10G/40G transmission and fiber sensors systems.
