(1)X represents power, for example, if the power is 2W, the model is FL-SF-780-2-CW

(2) You can also choose spatial collimation output at low power, with a diameter of 0.7-1mm. The single-mode polarization-maintaining fiber has a default FC/APC connector. Please pay attention to the cleanliness of the fiber end face when using it.

(3)Measurement of fiber delay by self-heterodyne beat frequency method
