WHAT TO CONFIRM
A few details make the choice clearer.
Select your route to see the questions that matter for this cable.
- Installation method and mechanical loads
- Fiber type, count and network requirements
- Jacket, protection and acceptance criteria
Every layer has a purpose.
Review the cable components, then confirm the drawing for the configuration you intend to order.
The approved cable drawing defines the final dimensions and materials.
Stranded optical core
Loose tubes are arranged around a central steel member.

GYTY53 configuration guide
Start with the construction and installation requirements below.
- Cable construction
- Stranded optical core · Core water protection · Inner PE sheathThe approved drawing defines materials, dimensions and tolerances.
- Optical configuration
- Specify the fiber category and countSelect against the network design, wavelengths and acceptance limits.
- Mechanical configuration
- Match the installation conditionsTensile, crush and bending limits depend on the complete cable construction.
Optical selection reference
If your selected fiber is G.652.D
- 1310–1625 nm
- ≤ 0.40 dB/kmG.652.D cable-attribute reference in ITU-T G.652 (08/2024), Table 2.
- 1530–1565 nm
- ≤ 0.30 dB/kmIncludes 1550 nm. These are standard limits, not a HONGKAI batch test result.
G.652 attenuation limits are not a blanket specification for short indoor cables, jumpers or drop cables. Fiber bending performance also does not determine the minimum bend radius of a finished cable.
Sources & scope
Public technical references checked September 2026. Manufacturer examples illustrate a construction; they do not identify HONGKAI’s source factory or establish the specification of your order.
Compare the construction.
Then narrow your shortlist.
Keep the route and protection requirements in view when you compare cable families.
FRP-reinforced steel-armored outdoor cable
GYFTY53
A stranded cable with an FRP center, inner sheath, steel-tape armor and outer PE jacket. Confirm armor, water protection and mechanical acceptance requirements for the route.
Central loose-tube fiber optic cable
GYXTW
A central loose-tube construction with steel-tape protection, parallel steel wires and a PE outer jacket. Start with your installation route, then confirm the mechanical and optical requirements.
Follow the equipment route for this cable.
GYTY53 · double-sheathed steel-armored — from fiber preparation to agreed acceptance and delivery. See HONGKAI equipment and process references matched to the listed construction.
The functions below explain how this construction is made. They are not a fixed machine count or a final equipment specification.
- 01
Fiber coloring & preparation
Start with the approved optical fiber. Apply and cure the specified identification colors, then rewind; if colored fiber is purchased, verify the incoming identification and package instead.
- 02
Loose-tube extrusion
Protect the fibers inside the specified loose tube. Confirm tube material, dimensions, excess fiber length and filling or dry water-blocking construction.
- 03
Loose-tube core stranding
Assemble the tubes and fillers around the approved steel center, with the specified binding and core water protection.
- 04
Inner PE sheath
Apply the specified inner sheath around the prepared optical core before the outer protection stages. Confirm the inner-sheath material and dimensions from the double-sheathed drawing.
- 05
Steel-tape protection
Apply the approved steel-tape protection and water-blocking package before outer sheathing. Confirm tape type, forming or corrugation, overlap and the required cable drawing.
- 06
Outer PE sheath & take-up
Apply the specified outer sheath, cool, check dimensions, mark and take up. Material grade, diameter, tooling and delivery length follow the approved order.
- 07
Inspection & delivery preparation
Complete the agreed optical and mechanical checks, inspection records, lengths, marking and packing. HONGKAI handles the agreed acceptance inspection and delivery; process videos are not batch test records.
The inner sheath precedes the steel armor and outer sheath. This sequence must not be shortened to a single sheathing pass; the shared sheathing footage does not demonstrate every pass or the armor stage. Final materials, equipment interfaces and acceptance follow the approved drawing and order.
Optical fiber coloring & rewinding
HONGKAI coloring and rewinding footage: identification ink is applied and cured before the fiber is rewound. Already-colored input can enter the next approved production stage. Equipment and process reference only. Not proof of the manufacturing source, full equipment configuration or acceptance of your cable batch.

Only matching process functions have video controls. Other stages retain their explanation where suitable footage has not been established. These clips are not one continuous factory tour or a batch inspection record.
Independent factories manufacture the finished cable; HONGKAI handles customer-facing supply, payment, agreed acceptance inspection and delivery. Some equipment customers also manufacture the cables we supply. The actual source, specification and acceptance requirements are confirmed for each order.
One partner for your finished-cable order.
HONGKAI connects cable-making equipment experience with finished-cable supply. Work with us on your requirement, then keep payment, acceptance inspection and delivery with HONGKAI.
A production perspective on cable selection
Our equipment business gives the cable discussion a practical starting point: how the fiber, reinforcement, protection and jacket fit the required construction.
A direct relationship with your supplier
HONGKAI is your customer-facing supplier. In our usual supply arrangement, you pay HONGKAI, and we handle acceptance inspection and delivery.
An agreed basis for acceptance
Set the cable drawing, specification, inspection scope and required records in the order documents, so the supply is assessed against your agreed requirement.
Who makes the finished cable?
Independent factories in China that use HONGKAI cable-making equipment. HONGKAI is the supplier, not the finished-cable manufacturer; the actual manufacturing source is confirmed for your order.
What establishes product acceptance?
The agreed cable specification, inspection scope and order records. Using HONGKAI equipment is a production relationship, not a finished-product certification.
Planning your own cable production?
HONGKAI also supplies cable-making equipment and production-project support. Start from the cable drawing, materials and production requirements.
Why source finished cable through HONGKAI?
HONGKAI combines cable-making equipment experience with customer-facing supply responsibility. Some of our equipment customers also manufacture finished cables supplied through HONGKAI. You work with HONGKAI on your requirement, payment, agreed acceptance inspection and delivery. The actual manufacturing source and specification are confirmed for your order.
How do I know whether GYTY53 fits my project?
A stranded loose-tube cable with a central steel strength member, inner PE sheath, steel-tape protection and outer PE sheath. Review ground conditions and installation protection together. Share your route, quantity, destination and any drawing or customer specification so the configuration can be reviewed.
Is HONGKAI the manufacturer of this finished cable?
HONGKAI supplies finished fiber optic cables and handles payment, acceptance inspection and delivery. The cables are manufactured by independent factories in China using HONGKAI cable-making equipment. The actual manufacturing source and acceptance requirements are confirmed for each order.
Who receives payment and handles acceptance and delivery?
For finished cable orders, HONGKAI receives payment and handles acceptance inspection and delivery. The actual manufacturer, specification and acceptance requirements are confirmed for your order.
What if I do not know the model or specification?
You can enquire without selecting a model. Send the route, intended connection, approximate quantity or a drawing. We will help identify the information needed for selection.
Can HONGKAI also help with cable-making equipment?
Yes. HONGKAI also supplies cable-making equipment and production-project support. The equipment configuration follows your cable drawing, materials and production requirements.
