A mechanical splice is showing a loss of 1.5 dB on a single-mode link. The tech pulls it apart, cleans it, and puts it back together, but it still reads 1.5 dB. The fiber ends were cleaved at a perfect 90-degree angle. What is missing?
Answers
AIndex matching gel inside the mechanical splice has dried out or was missing
BMechanical splices naturally have 1.5 dB of loss
CThe tech used the wrong color boot
DThe fiber needs to be cleaved at an 8-degree angle (APC)
