The outer diameter of the armored optical cable is approximately

The outer diameter of armored optical cables typically ranges from about 6 mm to 15 mm, depending on fiber count and armor type. Armored optical cables are designed with additional protective layers, such as steel tape or wire armor, over the fiber tubes and inner sheaths. This increases the overall diameter compared to non-armored cables.

For example, a 48-fiber multi loose tube armored cable may have a central tube of 2. 5 mm, an ECCS steel tape armor of 0. 15 mm, and an HDPE outer sheath of 1.

8 mm, resulting in a total diameter in the range of several millimeters beyond the core tube. Steel wire armored cables, such as those from Prysmian, can have outer diameters around 10 mm for 24-fiber configurations, with variations depending on the number of fibers and sheath material. In general, armored cables are thicker than standard single-mode or multi-mode cables, which may have diameters as small as 0.

25 mm to 0. 9 mm for single-mode fibers. The exact outer diameter depends on factors including: Number of fibers: More fibers require larger central tubes or multiple tubes.

Type of armor: Spiral metal tape or steel wire armor adds thickness. Sheath material: HDPE, PVC, or LSZH outer jackets contribute to the final diameter. For practical purposes, when planning installations, armored optical cables are usually considered to have an outer diameter between 6 mm and 15 mm, with higher fiber counts or heavier armor approaching the upper end of this range.
