How many optical fibers does this OPGW fiber cable contain, and what type are they?

OPGW cable features 24 cores of single-mode (SM) optical fibers. The fibers adhere to the G652D standard, which is widely used for long-distance communication due to its low attenuation and compatibility with various transmission systems.


What is the significance of the aluminum tube jacket in this fiber cable?

The aluminum tube jacket serves as a robust protective layer. It shields the optical fibers from mechanical damage, moisture, and environmental stress (such as temperature fluctuations). Additionally, aluminum provides good electrical conductivity, enhancing the cable's grounding performance in 110kV applications.


Is this OPGW cable specifically designed for 110kV power lines? Can it be used for higher or lower voltage systems?

Yes, this cable is engineered for 110kV power lines, with specifications optimized for the electrical and mechanical demands of this voltage class. While it may not be suitable for significantly higher voltages (e.g., 220kV or 500kV) without modifications, it could potentially be adapted for lower voltages, though it’s best to consult technical guidelines for specific applications.


Can the 24 cores be used for different types of communication signals simultaneously?

Yes, the 24 individual cores allow for parallel transmission of multiple signals. Each core can carry separate data streams (e.g., telemetry, SCADA, voice, or video), enabling versatile communication within the power grid without interference between cores.


What are the advantages of using single-mode (SM) G652D fibers in this OPGW cable?​

Single-mode G652D fibers offer several benefits: they support higher bandwidth over longer distances compared to multi-mode fibers, have lower signal loss (attenuation), and are compatible with most modern optical communication equipment. This makes them ideal for transmitting data, voice, and control signals across power grids.

We installed this 24core OPGW cable during a 110kV grid upgrade last year, and it’s been exceptional. The aluminum tube jacket held up perfectly through heavy rain and extreme temperature swings. The G652D fibers deliver consistent signal quality—our SCADA and telemetry systems run flawlessly.
