A consumable cassette line, not a machine: guidance-fibre spools in four capacity tiers — FS-S, FS-M, FS-L, FS-XL — that give a fleet vehicle a physical, hard-wired tether for comms or guidance. Radio and GNSS remain permitted and primary on this line; the fibre is the option for the worksite where a crew wants a wire instead, or as well.

The Fibre Spool Line is a consumable component family, not a vehicle: guidance-fibre payout cassettes — FS-S, FS-M, FS-L and FS-XL — built to give a fleet vehicle a physical, hard-wired tether for command, telemetry or guidance. Where a radio link can be jammed, spoofed or simply unwelcome on site, a fibre link cannot — because nothing about it broadcasts.
It sits on the Industrial line as a support system, the same way the Self-Charging Dock (CS-700) and the Deployable Relay Chain (CS-710) do: not a work platform in its own right, but the consumable and infrastructure layer other platforms draw on. Cargo Mover (CS-600) and Personnel Mover (CS-610) both carry an optional fibre fly-by-wire "fibre tail" for their most demanding profiles, and the cassette in this line is the part that makes that option real — a line-replaceable unit, swapped at the dock, not a bespoke fit per airframe.
One cassette grammar, one seat geometry, four capacity tiers. Pick the tier the mission's route length needs before launch; the spool, the tension path and the exit eye that gets the fibre off it cleanly are engineered once and shared up the whole ladder.
A radio link can be denied. A fibre link has to be cut.
Jamming, spoofing and RF-quiet requirements are electromagnetic problems. A hard-wired fibre tether doesn't have an electromagnetic signature to attack — the only way to break the link is to physically part the fibre, and that event is detectable the instant it happens.
Inside every cassette sits a wound fibre pack on a core, a tension element that keeps the paying fibre in its working band, and an exit eye — the last, radiused contact point that sets the fibre's departure cone as it leaves for the host termination. Three parts, one job: get fibre off the pack without ever letting it go slack or pulling it tight.
Two engineering questions are still open by design, and we say so rather than pretend otherwise. First, whether the pack pays out by rotating the whole spool or by staying static while fibre lifts off a bobbin end — each has a real trade-off, and the cassette housing reserves volume for either. Second, whether tension is held by a passive drag path or by an actively managed dancer-and-brake — again, both are drawn, neither is decided. What is fixed is the discipline: wind-pattern quality at the factory is what keeps a spool from birdnesting — a tangled, self-locking loop at the eye — under load on a moving vehicle.
Severance is engineered as a controlled event, not an accident. The fibre's own tensile limit is the fuse: a genuine snag parts the fibre before it can drag the vehicle off its line. Loss of optical continuity is sensed at the host end the instant it happens — and on every radio-equipped Industrial-line consumer, that loss fails over benignly to the dual radio links that were running in parallel the whole time.
FS-S, FS-M, FS-L and FS-XL are capacity classes on the same cassette architecture — the wound pack grows tier to tier; the seat, the latch and the mounting interface do not. A crew that has swapped an FS-S cassette has already learned how to swap an FS-XL.
Pick the tier the mission's expected route length needs before launch: a short precision-lift beside live infrastructure wants a small, light cassette; a long corridor run through an RF-quiet or heavy-EMI site wants more fibre on the pack. FS-XL sits at the ladder's edge deliberately — spool mass and volume grow with fibre length, and whether the top tier closes on mass at all is exactly the kind of question the engineering work exists to answer before it is printed as a spec.
Exchange is a dock task, not a field repair. The cassette seat and latch geometry are being developed jointly with the Self-Charging Dock (CS-700) so that empty-off, full-on is part of ordinary turnaround — the same logic that lets a Cargo Mover swap battery packs without touching a wrench.
Figures below are drawn from the Fibre Spool Line engineering drawing package (CSH-DWG-FIBRESPOOL-001). The source document states plainly that no fibre length, tension, bend-radius, mass or cost value exists in canon yet — so none is invented here.
We do not publish rung lengths for FS-S through FS-XL, because on this line that number is not yet a property of the design — it is the output of work still open. A length claim without the variables below attached would be a number for its own sake, so we decline to make one.
Source: drawing package CSH-DWG-FIBRESPOOL-001. No fibre material limit is invented here — every such field remains an open engineering question in the design record itself.
Radio and GNSS are permitted, and remain the default, right across the Industrial line — that doctrine does not change here. The Fibre Spool Line doesn't argue with it; it completes it, for the worksites where a purely radio link isn't the whole answer.
A precision lift beside live high-voltage infrastructure, an RF-quiet site next to sensitive equipment, a heavy-EMI industrial yard, a corridor where a crew simply wants proof of a hard-wired link for the record — none of those are jammed battlefields, and we do not price the fibre tail like a defence necessity. It is a mission-selected option: fit it when the worksite calls for a wire, run without it when radio alone is the right answer, and let a snag fail over benignly to radio rather than end the mission.
The overlap with the rest of the house is physical, not rhetorical. The same fibre spool, termination and cassette grammar that gives Cargo Mover and Personnel Mover their optional fibre tail is the platform this whole line stands on — engineered once by Canadian Shield's sovereign manufacturing base, drawn on wherever the fleet needs a wire it can trust.
One cassette. Every dock, every ladder rung.
On the Industrial line, the Fibre Spool Line sits beside the Self-Charging Dock (CS-700) and the Deployable Relay Chain (CS-710) as the surface line's shared infrastructure — support systems that make the work platforms above them turn around faster and stay linked with confidence, on a worksite the crew already knows how radio behaves on.
A Fibre Spool Line job is a loop around someone else's mission, not a mission of its own: the cassette is chosen, the fibre pays out while the host does its work, and the run ends clean — either recovered or, on a genuine snag, cut on purpose rather than by accident.
Before launch, the crew reads the mission's expected route length and worksite conditions — RF-quiet, heavy-EMI, beside live infrastructure, or simply "we want the wire on the record" — and seats the matching FS tier at the dock. Radio and GNSS are checked and live regardless; the fibre is an addition, not a substitution.
The host works its profile as normal — flying, driving or holding station — while the cassette pays fibre off the pack, held in its tension working band. Radio and GNSS keep running in parallel throughout; the fibre is a second, physical channel, not the only one.
At mission end the run either comes home for inspection under the reuse fork, or — on a genuine snag — parts at its own tensile limit, sensed instantly at the host, with radio already carrying the link. The empty cassette swaps out at the dock for the next leg; the depot re-arms while the crew moves to the next job.
Scenario illustrates the design intent of the operating loop. Payout architecture, tension control, reuse policy and tier rung lengths are exactly what the engineering and test program exists to close — and none of them is presented here as settled before it is.
The Fibre Spool Line sits beside the Industrial line's other support systems — and feeds the two work platforms that carry it as an optional fit.
