1. Fiber Count and Type:
   The fiber count within an OPGW cable is a direct determinant of its data transmission capability. It is crucial to ascertain how many fibers are necessary based on both current and anticipated communication needs. Additionally, selecting the correct fiber type (single-mode or multi-mode) is dependent on the application's distance and data requirements.
2. Cable Diameter and Weight:
   Installed alongside high-voltage transmission lines, OPGW cables must have appropriate cable dimensions and weight to ensure installation feasibility and structural soundness.
3. Tensile Strength:
   Assessing the tensile strength of an OPGW cable is paramount to ensure it can withstand the mechanical stresses incurred during installation, maintenance, and harsh weather conditions.
4. Short Circuit Rating:
   The short circuit rating demonstrates the cable’s capacity to endure brief surges of high electrical current. A sufficient rating is vital to prevent damage during electrical system failures.
5. Crush Resistance:
   OPGW cables are likely to confront compression from various angles. Ensuring adequate crush resistance will safeguard the optical fibers and maintain signal quality.
6. Thermal Performance:
   The thermal characteristics of OPGW cables can greatly affect their functionality in different temperature conditions. It is crucial to evaluate thermal expansion, contraction, and temperature ratings to guarantee dependable operation.
7. Corrosion Resistance:
   Given their exposure to the elements, OPGW cables must possess strong corrosion resistance to ensure durability and consistent performance over time.
8. UV Resistance:
   UV radiation can deteriorate cable materials; hence, it is essential to have UV-resistant OPGW cables to endure prolonged sunlight exposure.
9. Installation Considerations:
   A thorough understanding of the installation process is key to ensuring effective and safe cable deployment.
10. Testing and Certification:
    It is essential that OPGW cables adhere to relevant industry standards and certifications that confirm their quality and performance.
11. Cost and Long-Term Value:
    It is crucial to balance initial expenditures with long-term benefits when choosing OPGW cable specifications. Investing in high-quality cables may minimize future maintenance and replacement costs.
12. Supplier Reputation and Support:
    Selecting a reputable supplier known for quality products and strong customer support is essential to the successful installation of OPGW cables.

Furthermore, the Optical Ground Wire (OPGW) primarily serves the electric utility sector, positioned securely at the top of transmission lines. This placement not only shields sensitive conductors from lightning strikes but also facilitates telecommunications for both internal usage and third parties. With the dual aim of replacing traditional static wires and integrating optical fibers for communication purposes, OPGW must endure mechanical stress and electrical faults while protecting its delicate internal fibers.
