At which layer of ISO/OSI does the fiber optics work?
Fiber optics work at the Physical layer of the OSI model. The Physical layer is responsible for the transmission of raw data bits over a physical medium. This includes various types of cabling and signaling options, like fiber optics, which transmit data as pulses of light. The other options (Network layer, Transport layer, and Data link layer) involve higher-level functions like addressing and error checking, which are not related to the physical medium itself.
