Andrew works for a company that develops for a company that develops optic-fiber cables for transmission of data. which layer of the OSI model will define protocols that describe pin configurations for this medium?

the will define protocols that describe pin configurations for this medium

Physical layer

Explanation:

The physical layer happens to be the lowest in the OSI model. And it meant for sending the bits from one device to another. And this is the layer that has no concern with the bits meaning, as it deals with the physical connection set up only in the network, and with the reception and transmission of the digital signal. And hence, it is the physical layer that describes the pin configuration for this medium.
