Why each option
Fiber optic cable supports the highest transmission speeds of all listed options, with modern implementations reaching 100 Gbps and beyond using standards like 100GbE.
Fiber optic cable transmits data as pulses of light through glass or plastic strands, enabling speeds up to and exceeding 100 Gbps via standards such as 100 Gigabit Ethernet (100GbE). Its immunity to electromagnetic interference and low signal attenuation make extreme speeds achievable over long distances.
Coaxial cable is limited to much lower speeds, typically up to 10 Gbps in high-end implementations, and is generally used for cable TV or legacy Ethernet.
Infrared is a short-range wireless technology with very low bandwidth, typically well under 1 Gbps, and requires line of sight.
DSL (Digital Subscriber Line) uses telephone lines and is limited to speeds typically under 1 Gbps even in VDSL2 implementations.
