Through the adapter in the distribution box, the optical signal is led out by the optical jumper to realize the optical wiring function. An optical cable consists of three primary parts: the core, the cladding, and the protective sheath. The core is at the center of the optical cable and serves as the pathway for transmitting light signals. Surrounding the core is the cladding, which has a lower refractive index than the core. In the complex architecture of fiber optic networks, the Optical Distribution Frame (ODF) serves as the linchpin for organizing, protecting, and distributing optical signals.
