Which of the following options is the BEST choice for a high-speed data center backbone requiring minimal signal loss over long distances?
Single-mode fiber
Twinaxial cable
Multimode fiber
Coaxial cable
Single-mode fiber is the best choice for high-speed data center backbones over long distances due to its ability to transmit data through an extremely small core using laser light; this allows minimal signal loss and higher transmission speeds. On the other hand, Multimode fiber though similar, uses light emitting diodes (LEDs) and is more suited for short to medium distances due to modal dispersion. Coaxial cable is not typically used in high-speed data center backbones as it supports lower data rates and shorter distances than fiber. Twinaxial cable is primarily used for short distance connections and lacks the long-distance capabilities of single-mode fiber.
