All of our multifiber test equipment, including single-mode and multimode, are from testers manufactured by JGR, a test equipment manufacturer in Ottawa, Canada.

The figure below shows how we tested the insertion loss of the MPO to MPO patch cords, MPO to LC breakout patch cords, LC to LC patch cords, and plug type fixed attenuators. This is how our production line operates.
