Explanation

Optical-electric composite cable (A) solves the power supply problem by bundling optical fibers for data transmission together with copper conductors for electrical power in a single cable, eliminating the need for separate power infrastructure to reach remote terminals in an all-optical campus network.

Why the distractors are wrong:

• B (XGS-PON) is a 10G-capable symmetric passive optical network transmission standard - it defines how data is sent, not how power is delivered.
• C (Pre-connected ODN) refers to factory-terminated optical distribution network components for faster deployment - it addresses installation convenience, not power supply.
• D (SFP ONU) is a compact form-factor optical network unit - it's a device type, not a power delivery mechanism.

Memory tip: The word "composite" is your clue - a composite cable combines two things into one. When you see a remote terminal that needs both a signal and power but only one cable can run to it, think "composite = optical + electric in one jacket."
