Prepare the 1 m fiber end face (refer to the procedures in the previous experiments). 2) Mount both fiber ends onto the fiber mounts with the end faces extended out about 1 cm, align one with the detector head of the optical power meter so that the detector can capture the entire radiation from the fiber end. Figure 10 Photo of experimental setup 3) Measure the output power of the 1 m fiber and the fiber spool, respectively and then calculate the transmission loss coefficient using formula (4-1).
