Bi-Directional Event Locator

Find the true event location and average loss from shots taken at both ends.

Event Distance from End A Total Fiber Length (A to B) Loss from End A (dB) Loss from End B (dB)

Average loss-

Field TipDistance from End B = Total length − Distance from End A. Confirm both directions before digging.

Common MistakeUsing only one direction's loss. Gainers and losers are common - average both sides when you can.

About this calculationLocation from End B is total length minus distance from End A. Average loss is (Loss A + Loss B) / 2.
