What does this production route produce? This reference solution follows a three-stage route for GYXTW central loose-tube outdoor optical cable. HK-235 colors and rewinds optical fiber, HK-50 extrudes a jelly-filled PBT loose tube, and HK-90 applies parallel steel wires, corrugated metal-tape armor and a PE outer sheath. Final fiber count, armor material and equipment scope follow the approved cable drawing.

02 Cable structure → process
Open this GYXTW cable and trace each layer to its production stage.
Start with the assembled cable, open the reviewed structure, then choose one layer. The selected layer maps directly to HK-235, HK-50 or HK-90 and carries that context into the reference configuration.

This official HONGKAI video demonstrates the downstream HK-90+45 armoring and sheathing process used to complete a GYXTW cable. It gives buyers a practical view of Stage 03 after fiber preparation and central loose-tube production have been completed upstream.
Reference boundary: the video shows a GYXTW HK-90+45 armoring and sheathing process, but it does not confirm the final machine quantities, arrangement, capacity, interfaces, supplied scope, acceptance result or project performance.

04 Project responsibility
Define the GYXTW project boundary before the route is finalized.
The three-stage route above is a reference configuration, not a contractual supply scope. Buyer, HONGKAI and joint responsibilities become final only in the approved technical proposal or agreement.

07Route FAQ
Clarify the route before requesting a proposal.
These answers define the GYXTW reference route, what the supplied images can demonstrate, and what still requires project confirmation.
What GYXTW cable construction is this reference route based on?
The reference construction uses colored optical fibers inside a jelly-filled central PBT loose tube, followed by the specified water-blocking package, parallel steel strength members, corrugated steel-tape armor and a PE outer sheath. Fiber count, dimensions and material grades must follow the approved cable drawing.
Is the HK-235 fiber-preparation stage always required?
Not always. If qualified colored fibers are supplied in the required package and are ready for loose-tube production, the reviewed project scope may begin at HK-50. If coloring, rewinding or package preparation is required, the HK-235 reference stage must be evaluated with the fiber input specification.
Why does the page show three production stages?
The reference route separates fiber preparation, central loose-tube formation, and final armoring and sheathing. HK-235 prepares the fiber input, HK-50 forms the jelly-filled central loose tube, and HK-90 completes the outer protection package and PE sheath. Final interfaces between these stages remain project-specific.
Are HK-235, HK-50 and HK-90 the final equipment configuration?
No. They are reference production-stage models used to explain the process route. Final module quantities, dimensions, controls, utilities, optional systems and equipment interfaces are confirmed only after reviewing the cable drawing, materials, capacity target and factory conditions.
Can existing equipment or buyer-supplied materials be integrated?
Potentially, subject to technical review. HONGKAI must confirm material package sizes, tension ranges, line interfaces, control signals, dimensions, utilities, operating conditions and required tests before existing equipment or buyer-supplied materials are included in the proposed route.
What information is needed to confirm line speed and production capacity?
Please provide the cable drawing or specification, fiber count, finished diameter, required materials, product mix, target output, expected operating speed, reel sizes, shift pattern, available utilities, factory layout and project schedule. This reference page does not assume a standard project capacity.
Are the machine images and process video the final supplied equipment?
No. The images illustrate the HK-235, HK-50 and HK-90 reference stages. The related video demonstrates a comparable downstream HK-90+45 armoring and sheathing process only; it is not the complete three-stage project route, a final arrangement, a performance result or an acceptance record.
Are inspection, FAT, installation and training included?
Inspection points, FAT requirements, acceptance criteria, documentation, installation, commissioning, training, travel and on-site responsibility are project-scope items. Their exact content must be defined in the technical proposal and mutually approved commercial agreement.
Final cable construction, performance, equipment, acceptance criteria and supply scope are defined only in the mutually approved technical and commercial agreement.
