What is the main function of a cable certifier?

The primary function of a cable certifier is to verify network performance. This tool is essential for ensuring that the installed cabling systems meet specific standards and are capable of supporting the necessary data rates according to industry specifications. By performing tests on the installed cabling, a certifier can identify any issues such as attenuation, crosstalk, or return loss, which can impact overall network performance.

In a professional environment, verifying that the cabling system conforms to the required performance levels enhances the reliability and efficiency of the network. This certification process not only helps to ensure that the network will function as intended but also helps in troubleshooting any connectivity issues by confirming that the physical layer of the network meets the expected criteria.

Including extra features in cables is not a function of a certifier; rather, it's focused on testing existing installations. Estimating material costs and recording installation procedures are tasks associated with planning and project management, not the main function of a cable certifier. Thus, the specific role of verifying network performance aligns directly with the primary purpose of a cable certifier.
