=== Transmission Testing ===
The main question to be answered by testing the transmission rates of the fibers is to determine how well we need to polish the fibers. This is done by cutting a 25.625” length of fiber into four segments, gluing those segments back together, testing in the dark box and comparing the results to the control fiber. The reason for the multiple cuts of the fibers is to increase the loss of photons. The increased loss of photons will make it easier to identify if the extra time taken to polish the fibers completely is necessary. The epoxy used is 20-3238.
The segmented fiber will be polished three different ways; the first is using only with the emery board leaving a rough polish, the second adds the use of the three buffer boards, the third adds stripping the cladding before polishing.
Being tested right now is the rough polished fiber. Testing is not yet complete but preliminary results show that there is approximately a 73% transmission through the rough fiber compared to the control. A graph and proper analysis will be posted by Wednesday.
