Introducing Cisco Data Center Networking (DCICN, legacy) — Question 21

Which fiber optic cable type is used most often with a Subscriber connector?

Answer options

• A. dual-mode
• B. single-mode
• C. straight-mode
• D. multi-mode
• E. subscriber-mode

Correct answer: B

Explanation

The correct answer is B (single-mode), which is typically used in conjunction with Subscriber connectors due to its ability to transmit data over long distances with minimal loss. The other options, such as dual-mode, straight-mode, multi-mode, and subscriber-mode, do not accurately represent the standard fiber optic types used with these connectors.
