Signal fire Fiber Optic Tools OTDR Fiber Tester, 1310/1550nm Mini OTDR Mulit-Function Tester, Optical Light Source W/Built in OPM/OLS/VFL,Test Rang

The Signal Fire Fiber Optic Tools OTDR Fiber Tester has garnered a varied reception among its users. While some customers appreciate its affordability, particularly for smaller jobs, others find it lacking in reliability and functionality, particularly regarding its Optical Time-Domain Reflectometer (OTDR) capabilities. Many users have pointed out that the device primarily measures in meters, which may not meet everyone's expectations, especially for those accustomed to more advanced models. Additionally, while the tester is able to send and read light effectively, there seem to be significant challenges with the OTDR portion of the tool. Some reviews indicate that obtaining accurate readings can be frustrating, leading to the suggestion that users who require a dependable OTDR may do better investing in a more robust unit. A concerning issue highlighted involves the Optical Fault Locator (VFL). Users noted that a suitable adapter was missing, which poses safety risks due to potential exposure to harmful laser light if the device’s laser is activated while improperly connected. This has rendered the use of the VFL function practically ineffective for some users. In summary, while the Signal Fire Fiber Optic OTDR Tester offers an economical choice for basic jobs, those requiring more reliable and precise testing may find it lacking. The issues with the OTDR functionality and VFL adapter compatibility, coupled with the overall build quality, suggest this product may not meet the needs of all professional fiber technicians. **
