Explanation
External optical drives (DVD/Blu-ray) almost universally connect via USB because it provides both data transfer and power through a single cable, is universally supported across operating systems, and requires no additional configuration. Fiber optic connections are used for high-speed networking, not peripheral drives. Bluetooth is a short-range wireless standard unsuitable for the sustained data rates needed by optical drives. SATA is an internal interface used inside the computer chassis to connect internal drives-external devices use eSATA (which is not listed) or USB. USB is the overwhelmingly standard choice for external optical drives.
