Where Furukawa sits in the stack
Furukawa's placements in this catalog cover 4 parts, from layer 3 (networking & interconnect) to layer 8 (power generation & energy supply). None of them currently carries a sourced supply constraint tag. Across these parts it overlaps with other companies most often on the lines below.
What these parts are
- Fiber, connectors, structured cabling — The fiber optic cable, connectors, and structured cabling that carry optical signals between transceivers across a data hall or campus.
- Copper foil — The rolled or electrodeposited copper foil bonded to laminate cores that forms the actual conductive layers inside a PCB.
- LV cable, wire, tray, raceway — Low-voltage power cable and wire, and the tray and raceway systems that route and support it between switchgear, PDUs, and racks.
- HVDC — Manufacturers of high-voltage direct current converter stations and cable used to move bulk power over long distances or between asynchronous grids.
