CompTIA Network+ (N10-008) — Question 408

A company is opening a new building on the other side of its campus. The distance from the closest building to the new building is 1,804ft (550m). The company needs to connect the networking equipment in the new building to the other buildings on the campus without using a repeater. Which of the following transceivers should the company use?

Answer options

Correct answer: B

Explanation

The correct answer is B, 10GBASE-LR, which is designed for long-distance connections up to 10 kilometers over single-mode fiber, making it ideal for the 1,804ft distance. Options A (10GBASE-SW) and D (10GBASE-SR) are intended for shorter distances and would not be suitable without repeaters. Option C (10GBASE-LX4 over multimode fiber) is also not optimal for this distance when compared to 10GBASE-LR.
