Aim to have the start of the region of interest around or below +4000 units. 234 -1*. Ensure the far end of the region of interest does not enter a non-linear response scheme. 235 -1. **Consideration for Short Fibers:** 236 -1*. In cases where the fiber length is short and non-linear effects are not observed, set the Optical Power to its maximum. 237 -1*. **Power Scale:** The adjustment slider ranges from 0-100, representing the percentage of maximum power available. 238 - 239 -=== **Note on Optical Power Control** === 240 - 241 -* **Control Mechanism:** The slider provides a precise control mechanism to manage the intensity of light sent through the fiber. 242 -* **Monitoring and Adjustment:** Continuously monitor and adjust as necessary to ensure optimal performance. 243 - 244 - 245 - 246 - 247 - 248 - 249 - 250 - 251 - 252 - 253 - 254 - 255 - 256 - 257 - 258 - 259 - 260 - 261 - 262 - 263 - 264 - 265 265 === [[image:1706506304897-924.png]] === 266 266 267 267 [[image:1706506500585-231.png]]
