Eurolan's house code for the 39LD-S1 loose-tube distribution line — confirmed from a 48-count datasheet (4 tubes × 12 fiber), shown here extended to the 96-count / 8-tube version of the same product family. Tube order is open-ended: tube 1 Red, tube 2 Green, everything after that is undyed "Natural" PBT with no fixed color for a last tube, so tubes 3 and up look the same by color alone. Unused/filler tubes (no fiber inside) are marked Black, but that's a construction detail, not part of this cycle. Labeled generically as "Type 2" since other Eurolan lines may use the same code — unconfirmed. Note that Euroland makes S12 and TIA/EIA-598(EIA/TIA) aswell.
