What is the physical layer? I Definition from TechTarget

In the seven-layer OSI model of computer networking, the physical layer or layer 1 is the first and lowest layer: the layer most closely associated with the physical connection between devices. The physical layer provides an electrical, mechanical, and procedural interface to the transmission medium. The shapes and properties of the electrical connectors, the frequencies to broadcast on, the line code to use and similar low-level parameters, are specified by the physical layer. WebMar 31, 2024 · The conventional model of the optical communication system is constructed in a divide-and-conquer manner and consists of a series of model blocks, including symbol mapping, shaping filter, laser, modulator, fiber channel, amplifier, optical filter, detector, low-pass filter, and digital sampling, as shown in Figure 4A.
