CompTIA Network+ (N10-007) — Question 84

A network technician has been asked to install an additional switch in an IDF, but all of the single-mode fiber is in use between the IDF and MDF. The technician has deployed new transceivers that allow for the use of a single fiber stand, providing the additional fiber needed for the new switch. Which of the following has the technician deployed?

Answer options

• A. 1000BaseLX SFP
• B. Duplex GBIC
• C. Duplex SFP+
• D. Bidirectional SFP

Correct answer: D

Explanation

The correct answer is D, Bidirectional SFP, because it allows for simultaneous transmission and reception of data over a single fiber strand. The other options, such as Duplex GBIC and Duplex SFP+, require two fibers for operation, making them unsuitable for this scenario where a single fiber is needed.
