The purpose of a furcation unit is primarily to distribute optical power among various outputs. A furcation unit serves as an important component in fiber optic systems, particularly when transitioning from a single fiber cable to multiple fibers. It protects and organizes the fibers, ensuring that the optical signals can be effectively routed to different locations without loss of signal integrity.

Furcation units often involve several fibers being individually protected and managed to maintain performance, especially in environments where flexibility and safety are paramount. By allowing a single fiber's optical power to be split or shared among multiple outputs, the furcation unit plays a critical role in maintaining efficient fiber distribution within larger networks.

The other options do not accurately reflect the main function of a furcation unit in fiber optics: they either describe processes that are not the primary role of the unit, such as combining power from multiple inputs or checking continuity, or they mischaracterize the function of terminating fibers with protective coatings.
