Fiber Numbering Procedure

This page was created by Andrew Sampino, whose logbook for Spring 2016 can be found here

The fiber numbering system is the means by which the fused and unfused waveguides are identified.

Original System

Originally the fibers were collected in groups of thirty and given a group identifier with colored straps. Each strap color corresponds to a bundle number, the number to strap color conversion can be found in the first page of this google sheet. Within the bundles each fiber had a relative identifier consisting of two colored rubber bands. The two colors corresponded to a two digit base six number, which allowed for thirty six (six squared) intra-bundle numbers (on thirty were used). The band color to number conversion is as follows:

Purple = 0
Pink = 1
Orange = 2
Yellow = 3
Green = 4
Blue = 5

The rubber band closest to the fused end (or to be fused end) of the waveguide is the sixes place and the rubber band closest to the non fused end is the ones place. For example, purple blue corresponds to a zero in the sixes place and a five in the ones place giving a relative fiber number of five (0*6 + 5*5 = 5).
