Optics have thresholds for how strong or weak of a light level they can receive before they'll theoretically fail
- The purpose of this page is to help estimate if a particular optic will work on a particular fiber span
Terminology
- Power level
- The power level from optics is measured in microwatts but converted to dBm for ease of reading by humans
- dB is on a logarithmic scale
- The higher the dBm the stronger your receive level (the brighter your receive level)
- The lower the dBm the weaker your receive level
