• Tube and fiber colors follow the standard 12-color sequence.
• Letters continue past Z as AA, AB, AC… for large panels.
• "Skipping I" matches panels in the field that omit the letter I.
Field TipMatch the label style to the panel in front of you - many field panels skip the letter I.
Common MistakeUsing the wrong bulkhead size shifts every port letter/number after the first row.
