Revision history
VCSEL binning details
There are 5 separate grades for the VCSEL laser. As part of the manufacturing process the
VCSELs are manually sorted into the 5 grades which means for the mouse manufacturers it
is a simple process of choosing the right resistor combination for the grade of laser received.

The value required for R2+R2A (see Figure 1) will be clearly indicated on the label (e.g. Bin
match: 150 ohm).
