Final answer:
In an environment with high RFI and EMI, the best cable to use is a Fiber Optic Cable due to its immunity to electromagnetic interference, low loss, high bandwidth, and reduced crosstalk capabilities.
Step-by-step explanation:
When working in an area with high amounts of Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI), the type of cable that would function best is the Fiber Optic Cable. Unlike metallic cables, fiber optic cables use light to transmit data, which makes them immune to electromagnetic interference. Their structure allows for data to be transferred over long distances with minimal loss, which is referred to as low loss. In addition to this, they provide a high bandwidth, allowing more data to be transmitted simultaneously compared to traditional copper cables. Furthermore, fiber optic cables have reduced crosstalk, which means optical signals in one fiber do not cause interference in adjacent fibers.
