Fiber Cable Factory

30+ years

Our factory was found in 1992, first start with coaxial cable which was one of the biggest manufacturers in lin'an city.In year of 2001 started focusing on the production of optical cables.

30+ countries

In year of 2008, set up international sales department and sale optical fiber cable to more than 30 countries and have 18 years` rich experience to export cables .

• A layer of wrapped steel wires ensures the tensile strength of the cable, while protecting the loose tube, can play a very good role in rodent prevention.
• Good lateral compression resistance.
• Good mechanical and temperature performance.

• Transport/storage temperature: -40℃ to +60℃

• Standard reel length: 2km/drum or 3km/drum; other lengths are also available.

The delivery time for small batches of products is 7-15 days, for large batches it is 15-25 days. If there is an urgent need, please inform us in advance, and we will try our best to coordinate during production.

# Complete Introduction to Fiber Optic Cable Source Factory

## I. Fiber Optic Cable Source Factory

Our fiber optic cable source factory began production in 2001. We possess full-chain independent production capabilities, integrating fiber coloring, loose tube cabling, sheath extrusion, finished product testing, and patch cord processing. We master core raw materials and complete processes, and can independently develop and customize various national standards. We have a full set of testing equipment and formal industry certifications (CE, ISO, etc.).

### Core Judgment Criteria (Essential for a Genuine Source Factory)

1. Own fiber coloring machine, externally sourced bare fiber;

2. Complete automated production lines for cabling, sheathing, and secondary coating;

3. Cleanroom for fiber optic cables, strictly controlling dust attenuation and loss;

4. Full set of professional testing equipment (OTDR, loss tester, tensile/high/low temperature aging tester);

5. OEM/ODM customization available, support for large-volume procurement, and issuance of original factory test reports;

6. Possess specialized qualifications and certifications such as those for network access.

## II. Complete Production Process at the Source Factory

### 1. Fiber Optic Coloring Process

24-color standard spectrum inks are used for curing and coloring, distinguishing fiber order, preventing color mixing and fading, and meeting the identification requirements for fusion splicing.

### 2. Loose Tube Buffer Layer Processing

Colored optical fibers are placed into PBT loose tubes, filled with water-blocking grease, and with excess fiber length reserved. This provides resistance to tension, low temperature, and water pressure, forming the core structure for waterproof and damage-resistant optical cables.

### 3. SZ Stranding Cable

Multiple loose tubes are bidirectionally stranded using SZ stranding, combined with water-blocking yarn and a central reinforcing core to form the cable core; power optical cables (OPGW/ADSS) additionally have aramid and metal armor added to enhance tensile strength.

### 4. Sheath Extrusion Molding

PE/low-smoke halogen-free LSZH/flame-retardant PVC outer sheath is extruded; underground models add steel/aluminum armor for rodent and crush protection, while aerial models have a thickened weather-resistant sheath.
### 5. Comprehensive Factory Inspection (Core Advantage of the Source Factory)

100% Inspection of Each Reel of Optical Cable:

- OTDR Full-Range Attenuation and Breakpoint Testing;

- High and Low Temperature Cycling, Immersion Pressure Resistance, Tensile and Flattening Mechanical Testing;

- Flame Retardancy and Smoke Density (LSZH Optical Cable Special);

- Dispersion and Return Loss (Compatible with PON/APC Optical Paths).

### 7. Finished Product Packaging / Patch Cord Processing

Fiber optic cable wooden reel packaging; Supporting workshop capable of processing various fiber optic patch cords such as SC/UPC, SC/APC, and LC, as well as mixed end-face patch cords, achieving one-stop supply of optical cable + patch cords.
