There is no single machine list for every fiber optic cable factory. A complete fiber optic cable production line depends on six things: indoor or outdoor cable, the exact product, required capacity, project schedule, budget, and whether the customer needs machines only or a one-stop factory solution.
When a customer asks us for a “complete line,” we do not send the same quotation to everyone.
We first ask what cable the customer wants to make. Then we select the machines, testing equipment, and factory support for that product.
This simple step prevents three common problems:
- buying machines that the product does not need;
- missing an important production process;
- comparing quotations that do not include the same scope.
What Are the Six Questions We Ask First?
Before we discuss machine models or prices, we ask six practical questions.
1. Will you make indoor or outdoor cable?
Indoor and outdoor fiber optic cables are not made in the same way. Their structures, raw materials, and machines can be different.
This is always our first question.
2. What exact cable do you want to produce?
A cable name is useful, but a picture is often even better. The customer can send us any of the following:
- a product name or model;
- a cable photo;
- a cross-section drawing;
- a technical specification;
- a sample cable.
If the customer says only, “I want to make fiber optic cable,” we still do not know which production line is correct.
For example, an FTTH drop cable, an indoor tight-buffer cable, and an outdoor loose-tube cable use different production routes. Our guide on how to choose the right fiber optic cable production line explains these product differences in more detail.
3. What production capacity do you need?
We ask for the planned daily, monthly, or yearly output. We also ask how many shifts the factory will run.
Capacity affects:
- machine speed;
- reel and drum size;
- automation level;
- the number of production lines;
- the size of the supporting equipment.
A customer making one product in one shift may need a different solution from a factory making several products around the clock.
4. When do you plan to start production?
The start date affects the whole project plan.
The customer needs time to confirm the cable, prepare the factory, manufacture and ship the machines, install the equipment, train operators, and test the first cable.
A clear schedule helps us separate urgent needs from equipment that can be added later.
5. What is your approximate budget?
A budget range helps us recommend the right equipment level.
Without it, a proposal may be too basic for the production target or more expensive than the project needs. When the cable and capacity are clear, we can discuss different equipment and automation options.
6. Do you need machines only or a one-stop solution?
Some customers need one machine. Some need a complete production line. A new investor may need a wider factory plan.
A one-stop project can include:
- main production machines;
- online inspection equipment;
- laboratory test equipment;
- factory support equipment;
- layout and utility guidance;
- installation and commissioning;
- operator training;
- recommended spare parts.
The final scope still depends on the product, factory conditions, local resources, schedule, and budget.
Are You Making Optical Fiber or Fiber Optic Cable?
Optical fiber manufacturing and fiber optic cable manufacturing are two different industries.
This is one of the most common misunderstandings in early customer discussions.
| Project | What it does | HONGKAI scope |
|---|---|---|
| Optical fiber manufacturing | Draws glass fiber from a preform and applies the primary coating | Not supplied by HONGKAI |
| Fiber optic cable manufacturing | Uses purchased coated fiber and turns it into a protected indoor or outdoor cable | Supplied by HONGKAI |
HONGKAI supplies fiber optic cable production equipment. We do not supply optical-fiber drawing towers or a complete fiber-drawing technology-transfer package.
Our production scope normally starts with qualified coated optical fiber purchased by the cable factory. The next processes identify, protect, combine, jacket, test, and package that fiber.
If you are unsure which project you are planning, send us the intended final product. A photo or sample can quickly show whether the requirement is fiber manufacturing or cable manufacturing.
Why Must We Separate Indoor and Outdoor Cable?
Indoor and outdoor cables solve different installation problems.
| Question | Indoor cable | Outdoor cable |
|---|---|---|
| Where is it normally used? | Inside buildings or protected environments | Ducts, aerial routes, outdoor networks, or direct-buried applications |
| What is the main design need? | Compact size, flexibility, and indoor installation performance | Water protection, mechanical strength, and environmental protection |
| What materials may be used? | Tight-buffer materials, yarn reinforcement, and an outer jacket | Loose tubes, strength members, water-blocking materials, optional armor, and an outer jacket |
| How do we select machines? | From the exact indoor cable structure | From the cable structure, fiber count, protection level, and required output |
This table shows the basic difference. It is not a fixed specification for every cable.
An indoor cable may use a tight-buffered production line. An Dây chuyền sản xuất cáp thả FTTH can combine fiber, strength members, and the outer jacket in a more direct process.
Many outdoor products use loose tubes, but their final structures still differ. An ADSS cable production line does not use the same protection system as every duct or armored cable.
That is why we ask for the cable name, photo, drawing, or sample before selecting equipment.
What Does a Typical Outdoor Cable Process Look Like?
The following is a simple example for a common stranded loose-tube outdoor cable. It is không the required route for every outdoor product.
Coated optical fiber → coloring → loose-tube production → cable-core assembly → optional water blocking or armor → outer sheath → testing and packaging
Step 1: Coated optical fiber enters the factory
The cable factory buys qualified coated optical fiber. The fiber is checked before production and loaded onto the correct pay-off reels.
This is the starting material for HONGKAI cable production equipment.
Step 2: The fibers are identified
A coloring machine applies different colors so operators can identify individual fibers later.
This machine may not be needed if the factory already buys fiber with the required colors or uses another approved identification method.
Step 3: The fibers are placed inside loose tubes
A loose-tube line puts several fibers inside a protective plastic tube.
The tube helps protect the fibers during the later cable-making stages. The tube material, number of fibers, and filling method come from the cable design.
Step 4: The tubes are assembled into a cable core
For many stranded designs, an SZ stranding machine places the loose tubes around a central strength member.
In simple words, this machine builds the main cable core. Some central-tube or special cable designs do not need this process.

Step 5: Protection materials are added when required
The cable may need water-blocking yarn, water-blocking tape, filling compound, strength yarn, steel tape, or another protective material.
These items are selected from the cable structure and installation environment. They are not automatically required for every outdoor cable.
Step 6: The outer jacket is added
Các dây bọc cáp adds the final outer layer around the cable core.
The line can also include printing, length measurement, diameter inspection, pulling, and take-up. The exact tooling and material system must match the cable.
Step 7: The finished cable is tested and packed
The cable is wound onto the correct drum. The factory checks the product before shipment.
Testing may include optical, dimensional, and mechanical checks. The exact test plan follows the cable standard and customer specification.
Does a Complete Project Include More Than Production Machines?
Yes. A factory cannot run steadily with production machines alone.
When a customer has a clear cable and already owns a factory, only one or two new machines may be required. A new factory normally needs a wider checklist.
Main production equipment
These machines directly make the target cable. The list may include coloring, loose-tube, stranding, armoring, tight-buffer, or sheathing equipment.
The correct combination comes from the cable product.
Inspection and test equipment
Online devices check the cable while it is being produced. Laboratory equipment checks the raw materials, process samples, and finished cable.
The test list must match the product. IEC 60794-1-1:2023 provides a general framework for optical fibre cable specifications, but the customer specification decides the final tests and limits.

Factory support equipment
Depending on the process, the project may also need:
- electrical power distribution;
- cooling water or a cooling system;
- compressed air;
- nitrogen supply where the selected process requires it;
- material drying and handling;
- cable reels, drums, and storage;
- safe space for operators and maintenance.
Auxiliary equipment should come from the real process requirements. It should not be added only to make a quotation look more complete.

How Do We Configure the Project for Different Buyers?
We do not use the same proposal for every customer.
New factory owner
A new investor may not know the exact cable or machine sequence.
We first help define the target product and capacity. If the customer has not selected one outdoor cable, we can discuss a broader outdoor-cable factory plan based on the intended market and previous project experience.
The proposal can then separate:
- machines required for the first products;
- optional machines for future products;
- testing equipment;
- factory support equipment;
- services needed before production starts.
Existing production manager
An experienced factory usually knows the process it wants to add.
The discussion focuses on the target cable, extra capacity, reel sizes, existing machines, factory utilities, and the planned installation time. The customer may need one machine, one additional line, or a replacement for a production bottleneck.
Technical buyer comparing suppliers
A technical buyer needs to compare the same scope.
Check:
- which cable products the line can make;
- the agreed production capacity;
- which machines and testing items are included;
- which auxiliary systems are excluded;
- the parts and controls used;
- installation, training, and after-sales support;
- the agreed acceptance method.
Two quotations can have very different prices because their capacities and included items are different.
What Are the Three Most Common Quotation Mistakes?
Mistake 1: Mixing fiber drawing with cable production
First decide whether the factory will manufacture optical fiber or buy optical fiber and manufacture finished cable.
HONGKAI works in the second area.
Mistake 2: Asking for a complete line without defining the cable
“Outdoor cable” is still too broad.
Send a cable name, picture, sample, or cross-section. This helps us identify the correct production route.
Mistake 3: Comparing price without comparing capacity and scope
One quotation may include only production machines. Another may include testing equipment, auxiliary equipment, installation, training, and start-up support.
Compare what each quotation can produce and what it includes—not only the final price.
What Information Should You Send Us?
You do not need to prepare a complete factory specification for the first conversation.
Start with:
- Indoor or outdoor cable.
- Cable name, photo, sample, or drawing.
- Required production capacity.
- Planned project start date.
- Approximate budget.
- Machines only or one-stop project support.
Explore our fiber optic cable production line solutions if you want to compare common indoor and outdoor product routes.
Then send the six items to the HONGKAI team. We can use them to prepare the correct questions and a practical equipment discussion for your project.
A complete line should be complete for the cable you plan to sell—not simply a long list of machines.
