Which type of optical fiber cable consists of multiple individually jacketed strands under a single overall jacket?

The type of optical fiber cable that consists of multiple individually jacketed strands under a single overall jacket is indeed the breakout cable. This design allows each fiber strand to be protected by its own jacket, making it easier to manage and terminate fibers individually without the need for specialized splitting equipment.

This individual jacketing provides several advantages, including increased flexibility and ease of installation for connecting to network equipment. It also allows for easier repairs since a single strand can be accessed and replaced without disturbing the others. This construction method enhances performance and safety by reducing the risk of damage to adjacent fibers during handling or installation.

In comparison, loose tube cables contain multiple fibers within a single protective tube, which is typically not individually jacketed. Ribbon cables consist of multiple fibers organized in a flat ribbon-like structure but do not have individual jackets. Plenum cable refers to the fire-resistance rating for cables installed in air-handling spaces and does not specifically address the construction of the fiber strands within the cable.
