According to the latest 568B.3 standard, which connector style is specified?

• A. ST
• B. SC
• C. LC
• D. Any Connector Meeting Focused on Standardization

Answer: (D)

The key idea is that this standard defines performance and compatibility requirements for fiber optic connectors rather than prescribing a single physical connector style. It sets testing methods and acceptance criteria for factors like insertion loss, return loss, durability, and environmental performance. Because it focuses on meeting those criteria, any connector type that demonstrates conformance is acceptable under the standard. That’s why the best answer is the option indicating that any connector meeting the standard is specified. ST, SC, and LC are common connector families, but nothing in the standard forces you to use one particular style—what matters is that the connector you use meets the specified performance criteria.
