Final answer:
The subject of this question is Technology and the concept being discussed is fiber optics.
Step-by-step explanation:
The subject of this question is Technology and the concept being discussed is fiber optics.
Fiber optics is the transmission of light down fibers made of plastic or glass, using the principle of total internal reflection. In this context, the termination of fiber optic cables is done using a push-pull mechanism. This mechanism helps make the connection between the fiber optic cables.
