Final answer:
The statement regarding the exclusive use of AFL Fujikura connectors for AFL Fujikura fiber is false, as fiber optic connectors are not brand-specific. Refraction is essential in fiber optics for signal transmission, and tension in a connector is the stretching force that pulls towards the center, which is true. The preference for short-staple cotton over long-staple before the cotton gin's invention is false.
Step-by-step explanation:
The statement 'Only AFL Fujikura connector ends can be used to terminate AFL Fujikura fiber' is false. In fiber optics, connectors are not typically proprietary to the fiber brand. Technicians can use a variety of connectors as long as they match the fiber type (single-mode or multi-mode) and meet the performance specifications required for the application.
Refraction is a phenomenon where light changes direction as it passes from one medium to another with different densities. This concept is true for its application in fiber optic cables, as it is the principle that allows light signals to be transmitted with minimal loss.
Tension in a connector or cable refers to the force applied that stretches the material and attempts to pull it apart. The statement that tension is the result of opposite forces in a connector, such as a string or cable, that pull apart in a direction parallel to the length of the connector, is true. The tension at the ends pulls toward the center of the connector.
