Which of the following is not a primary function of an OTDR?

Identifying Cable Length
Evaluating Connector Quality
Measuring Bandwidth
Locating Splices

The correct answer is: Measuring Bandwidth

Choosing "Measuring Bandwidth" as the option that is not a primary function of an OTDR (Optical Time Domain Reflectometer) is accurate because OTDRs are primarily designed to analyze and troubleshoot the physical properties of fiber optic networks rather than evaluate bandwidth. An OTDR works by sending pulses of light down the fiber and analyzing the light that is reflected back due to various events such as splices, connectors, and breaks in the fiber. This allows the technician to determine the length of the cable, evaluate the quality of connectors, and locate splices by measuring the time it takes for the light pulse to return. In contrast, measuring bandwidth relates to the data transmission capacity of the fiber and involves other tools and methods, typically focusing on the throughput and data rates rather than the physical integrity of the fiber itself. Therefore, measuring bandwidth is outside the scope of what an OTDR is designed to do.
