(1) X represents power. For example, the model is FL-SF-776-2-CW for 2W output power.
(2) Spatial collimated output (0.7-1mm diameter) is also optional for low power. The single-mode polarization-maintaining fiber comes with a standard FC/APC connector. Please ensure the fiber end face is clean before use.
(3) Measured by Fiber Delay Self-Heterodyne Beat Note Method.
