Differences between airblowing cable and regular optical cable:
1. Construction Method:
Airblowing cable: Airblowing cabletechnology uses the "parent duct - sub-duct - microduct" installation mode.
Regular optical cable: It is directly laid in existing parent ducts (such as conduit or duct).
2.Installation Method:
Airblowing cable: When using Airblowing cable on highways, the Airblowing cable need to be blown first, followed by the blowing installation of micro cables.
Regular optical cable: It is typically installed manually or by blowing without the need for a separate duct system.
3. Maintenance:
Airblowing cable: Airblowing cable are equipped with pre-installed splice closures during the installation process, allowing for quick restoration of communication lines by dragging individual closures in case of cable issues. Micro cables and regular optical cables use the same fibers, so there are no concerns regarding fusion splicing between microducts and regular cables.
Regular optical cable: Regular cables are not equipped with pre-installed splice closures, and maintenance personnel face difficulties and longer repair times when dealing with cable issues due to the lack of access points along the cable route.
4. Technical Parameters:
Airblowing cable: As the name suggests, Airblowing cable have smaller outer diameters compared to regular optical cables, making them a suitable solution for constrained or limited highway duct resources.
Regular optical cable: Regular optical cables have larger outer diameters, typically above 8mm, which can pose challenges when duct resources are limited.
5. Airblowing cable Structures:
Non-metallic central-tube microducts are typically used for micro cables with 24 fibers or fewer, while non-metallic layer-stranded microducts with 24 fibers or more are commonly used in highway applications. Regular optical cables have larger diameters, and microducts offer advantages in situations with limited duct resources.
