Product Description
Structure Design:
Applications: Aerial, Overhead, Outdoor
Main Features:
- High quality IEC607948 IEEE1138 standards for designing, testing, and producing with grade A materials available to ensure long-term reliability.
- Engineering support supervising and providing its own line of accessories hardware.
- Seal stainless steel tube superior protection to the fiber optical to moisture and extreme environmental conditions such as lightning.
- To construct OPGW must cut power, resulting in greater loss, thus OPGW must be used in constructing a high-pressure line over 110kv.
- Apply to the transformation of old lines.
Quality Control:
OPGW cable is mainly divided into: central-type stainless steel tube OPGW, stranded-type stainless steel tube OPGW,
al-covered stainless steel tube OPGW, aluminum tube OPGW, lightning resistant central stainless steel tube OPGW with compressed wires and OPPC.
Test Types:
Type test: May be waived by submitting maker’s certificate of the similar product performed in an internationally acknowledged independent test organization or laboratory. If performed, it will follow an extra type test procedure agreed upon between purchaser and manufacturer.
Routine test: The optical attenuation coefficient on all production cable lengths is measured according to IEC 60793-1-CIC (Back-scattering technique, OTDR). Standard single-mode fibers are measured at 1310nm and 1550nm. NZDS fibers are measured at 1550nm.
Factory test: Carried out on two samples per order in the presence of the customer or representative. Requirements are determined by relevant standards and quality plans.
Packaging Requirements:
- 1：All cables shall be wound on treated wooden spools that are not returnable
- 2：Cable ends must be firmly secured to the spool and protected with waterproof shrink caps
- 3：Each spool must include:
A protective outer layer of plastic wrapping
Reinforcing wooden slats to ensure stability
At least 1 meter of free cable end reserved for testing
A standard spool length of 3000mm (with a permissible tolerance of ±2%)
Cable Identification:
The outer jacket must display:
- 1、Unique sequential numbering every 1m (±1% variance permitted)
- 2、 Additional repeating markings at 1m intervals showing:
Product code and fiber count
Manufacturer identification
Production date (month/year)
Total cable length
Standard Packaging Dimensions:
| Length | Container | Size (L×W×H) | Net Mass | Total Mass |
|---|
| 2 km | Wood spool | 90×75×90 cm | 156 kg | 220 kg |
| 3 km | Wood spool | 100×68×100 cm | 240 kg | 280 kg |
| 4 km | Wood spool | 109×75×109 cm | 300 kg | 368 kg |
| 5 km | Wood spool | 129×72×129 cm | 400 kg | 480 kg |
Technical Reference:
- 1、 Standard cable diameter: 10.0mm
- 2、Maximum span distance: 100m
- 3、Contact sales team for complete technical specifications
Spool Marking Standards:
Permanent markings (minimum 25-30mm height) must appear on both sides of each spool:
- 1、 Company name and trademark
- 2、Contained cable length
- 3、Cable specifications (type/fiber count)
- 4、Winding orientation
- 5、Weight measurements (gross/net)
Note: All wooden packaging materials must undergo proper fumigation treatment prior to use.

Opticlink have a total of 8pieces production lines, include FTTH drop cable, Central loose cable and stranded fiber cable production , modernized dust-free workshops, and high-performance processing equipment. From raw material procurement, to finished product processing, to product quality testing, to packaging and export, we have a full range of production lines. The following are some of the actual photos of the workshop
1. What makes OPGW-4 different from other OPGW cable types?
OPGW-4 uses a central stainless steel loose tube that is aluminum-covered, combining high mechanical strength, thermal protection, and lightweight conductivity—making it suitable for long-span high-voltage transmission towers.
2. Is this cable suitable for areas with lightning and high EMI?
Yes. The aluminum-covered design provides excellent grounding capability, while the stainless steel tube protects the optical fibers from electromagnetic interference (EMI), ensuring signal integrity even in harsh utility corridors.
3. What are the fiber specifications available?
OPGW-4 supports 12 to 144 cores, using G.652D (standard SMF) or G.655C (NZDSF), offering flexibility for utility SCADA, protection, and telecom systems.
4. How is the cable installed on transmission lines?
It’s installed as the topmost ground wire on transmission towers using tension clamps, dead-end grips, and suspension fittings. Its dual function (grounding + data) reduces material and maintenance cost.
5. What are typical use cases for OPGW-4?
OPGW-4 is widely used in:
220kV and above high-voltage transmission lines
Smart grid and SCADA systems
Electrical substations
Remote monitoring and protection communication
