保偏光纤耦合器(也称保偏拉锥分路器,FBT Coupler),能使在光纤中传输的光信号在特殊结构的耦合区发生耦合,进行光功率的再分配,制作不等分分光路,广泛用于光纤传感,光纤通信系统。

Polarization-maintaining fiber coupler (known as polarization-maintaining taper splitter,or FBT Coupler) allows the optical signals transmitted in the fiber to be coupled in the coupling zone of the special structure, realize the redistribution of optical power, and make unequal splitters, which are widely used in optical fiber sensing and optical fiber communication systems.

备注:

*以上指标是不加连接头的参数.(Above specification are for component without connector)

*对于增加连接头的器件,,回损将会降低5dB,消光比也会降低2dB左右.( RL will be 5dB lower and ER will be 2dB lower for component with connector)

*保偏光纤和连接器是慢轴对准。(The PM fiber and connector key are aligned to the slow axis)
