What is the significance of Total Power Accepted by Fiber?

The total power accepted by the receiving fiber is a crucial parameter in optical communication systems. It signifies the amount of light power that successfully makes it from the emitting (sending) fiber into the receiving fiber. The higher the total power, the more efficient the energy transfer between the two fibers, which can lead to better signal quality and longer transmission distances. Conversely, if total power is low, it means a significant amount of light power is lost due to factors like misalignment or separation, which can degrade the signal quality and limit the communication range.

How to Calculate Total Power Accepted by Fiber?
