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.

AFiberCorrect

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.

BCoaxial

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.

CInfrared

Infrared is a short-range wireless technology with very low bandwidth, typically well under 1 Gbps, and requires line of sight.

DDSL

DSL (Digital Subscriber Line) uses telephone lines and is limited to speeds typically under 1 Gbps even in VDSL2 implementations.
