Question:
Is the NF-859GT Network Cable Tester suitable for POE applications?
Answer: Yes, the NF-859GT is specifically designed to test Power over Ethernet (POE) connections. This makes it essential for those installing or maintaining POE devices like IP cameras or wireless access points. It can check whether the media is properly delivering power alongside data, helping prevent malfunction in devices that rely on this technology for operation. This feature is particularly useful for technicians working on security systems or smart buildings. -
Question:
How does the optical power meter feature work in the NF-859GT?
Answer: The optical power meter of the NF-859GT works by accurately measuring the light power level in fiber optic cables. It provides results in decibels (dBm), allowing technicians to determine the quality of fiber connections. This is crucial in ensuring that signals are sufficient for effective communication. For example, when troubleshooting a slow network, using the optical power meter can identify weak spots in your fiber lines where signals may be degraded. -
Question:
Can I use the NF-859GT for non-network related wiring?
Answer: While the NF-859GT is primarily designed for network cables, its versatility extends to testing phone lines and other wiring setups.

YILTION Network & Cable Testers Editorial Review
The customer experiences shared about this testing tool paint a mixed picture of its usability and functionality. Users have reported that, once accustomed to its operation, the device becomes a valuable asset for troubleshooting networks. With a plethora of features including continuity checks, a built-in TDR, and PoE testing, it does prove to be multifunctional at an attractive price point, which has impressed many, especially those transitioning from more expensive tools. However, the device’s user interface and instructions have drawn significant criticism. Many users describe the manual and on-screen guidance as poorly translated, confusing, and at times contradictory. The complexity of connecting to the correct RJ45 ports for different tests requires careful attention, leading to an unnecessarily cumbersome experience that detracts from its overall efficiency. While certain features, like port flashing and PoE testing, work well, users have encountered issues with the scanning capabilities, both digital and analog, indicating shortcomings in performance. The design of the wand, including its thick probe, has also been flagged as an impediment. A notable inConsistency is observed in the length testing feature, which was more frustrating than informative and ultimately miscommunicated in its error messaging. In summary, the device serves as a competent tool for network professionals who can navigate its complexities, offering valuable functionalities at a low price point. However, potential users might face a steep learning curve due to its confusing operational aspects. **
