Capability, not a product list
Why does one factory make both fiber optic patch cords and USB-C cables?
Because they are not two businesses. They are one process — precision termination and cable assembly — carried by two media: glass and copper.
- One termination floor, two sets of tooling
- One moulding shop for strain-relief boots and overmoulds
- One 100% test bench and one packing line
The direct answer
Same process, different carrier
Buyers ask this because a supplier that lists everything is usually good at nothing. The answer here is a process answer, not a catalogue answer.
- Both products exist because a conductor has to be terminated into a connector and that joint has to be protected. Fiber and copper differ in tooling and test method, not in factory.
- The moulding shop, the potting line, the test bench and the packing line are the same physical assets. Splitting them into two factories would double the cost and change nothing about quality.
- What differs is the work station inside the same room: grinding and ferrule assembly for fiber, crimping and soldering for copper.
Process by process
What is actually shared
Every step below runs under one roof, and most of the equipment is used by both product families.
| Process step | Fiber optic patch cords | USB-C cables | Shared? |
|---|---|---|---|
| Termination | Polishing, ferrule assembly | Contact crimping, soldering | Same floor, different tooling |
| Moulding / overmoulding | Strain-relief boot | Inner mould, outer jacket | Same moulding equipment |
| Potting / reinforcement | Armored patch cords | Waterproof and reinforced versions | Same process |
| 100% testing | Insertion loss, return loss | Continuity, hipot, 240 W load | Same bench, different fixtures |
| Packing and dispatch | Same | Same | Fully shared |
Where the lines stay separate
What is not shared
A supplier who claims everything is identical is not telling you the truth. These three genuinely differ.
Tooling
Ferrule polishing fixtures and crimp applicators are not interchangeable. Each line keeps its own, and neither is used as a spare for the other.
Test method
Fiber is measured optically — insertion loss and return loss. Copper is measured electrically — continuity, hipot and current carrying at 240 W. Same bench, different instruments.
Skills
A polisher and a crimp operator are different trades. We train them separately and do not rotate people between the two lines.
What it buys you
Why this matters on a purchase order
One purchase order
Fiber patch cords and USB-C assemblies can ship on one document set, one invoice and one container.
One audit
A single factory audit covers both lines, instead of two suppliers and two sets of paperwork.
One quality rule
The same incoming inspection, the same traceability and the same 100% test rule apply to both families.

Buyer questions
Questions this page usually answers
Do you manufacture both, or resell one of them?
We terminate both in-house, in the same plant. Fiber patch cords run on the optical line and USB-C assemblies on the copper line, and both use the shared moulding, potting, test and packing assets described above.
Can fiber and copper go on one order?
Yes. Mixed orders are consolidated into one shipment and one document set, and the packing list keeps the two product families separate so customs can read them clearly.
Which line is your main business?
Connectors and cable assemblies are the main line. Fiber optic patch cords are a supporting line for buyers who prefer one supplier for both.
What insertion loss do you specify on patch cords?
Insertion loss is specified at 0.3 dB or better. Ask any supplier for the number and the test method before you compare quotations.
