Oh, that's a fascinating piece of hardware engineering! Those pictures depict something you don't see every day—routing optical fibers using electrical jumpers on a PCB (Printed Circuit Board).

Generally, PCBs are known for their intricate traces and layers to connect electronic components. But using electrical jumpers for optical fibers suggests a highly specialized design, perhaps for advanced communication or sensing applications.

Optical fibers can handle high data rates and long-distance transmission with minimal loss, making them perfect for high-speed networks or complex data syste…
