Testing with a professional multi-function OTDR-1500
1500 is its ability to display results for two wavelengths
LCD that ensures a clear and visible display interface suitable for field techs.
Compliance with industry standards Regulatory compliance is necessary for work that must meet IEC, TIA/EIA, or BICSI certification requirements, and is vital for enterprise networks, data centers, telecom backbones, and government contracts. For example, the safety level of the laser used in this device is: CLASS1 LASER PRODUCT: 21 CFR 1040.10 or CLASS 3A LASER PRODUCT: IEC 60825-1:Ed.2:2001
simultaneously. By selecting the ‘test conditions’ button, users can typically choose to test at both 1310 nm and 1550 nm wavelengths. Having access to both wavelengths is useful, as certain faults are more easily detected at specific wavelengths depending on their nature. The device also generates a graphical representation to help identify faults within the fiber optic cable. The ‘analyze’ button on the screen provides access to this event map, which lists all detected events along the tested fiber. An integrated ‘help’ section guides users through interpreting the graphical data, reducing the chance of misinterpretation. As a high-end device, the OTDR- 1500 is more efficient, reducing time spent on troubleshooting and documentation. It features a rugged design and an intuitive UI, with an advanced anti-reflection
Conclusion
Professional tools such as the OTDR-1500 offer greater durability and reliability, supported by manufacturers with regular firmware updates, straightforward maintenance, and extended technical support. This makes them a sound long-term investment. By delivering higher accuracy and resolution, detecting subtle faults, and producing clear, actionable data, these solutions provide an effective means to optimize fault diagnosis on large-scale fiber installations. As FTTx evaluation continues to develop, Jonard Tools remains well-placed to support access network builders and maintainers in achieving their objectives, enabling smarter, more efficient, and sustainable use of professional-grade OTDRs.

When set to Automatic test mode, the OTDR-1500 adjusts its settings automatically to test the connected fiber link. Once the test is complete, the device performs curve analysis and marks event points based on the configured loss analysis threshold. The event list then appears in the main operation window for easy review.
instrument’s optical output connector and the end face of the fiber under test clean. Contamination from substances such as ointment or other pollutants can cause measurement errors and, in severe cases, prevent the device from testing the optical fiber altogether. Detailed and interpretable traces This professional-grade tool provides clear, actionable data that can be easily analyzed and documented (Figure 2), including built-in analysis software or advanced PC software compatibility. Some of the events represented in a trace are: ■ Distance: Measured along the horizontal axis, it shows the location of events within the
fiber. Usually this is from the event point to the reference origin. ■ Amplitude: Measured along the vertical axis, it shows the intensity of the reflected light, indicating the amount of signal loss at each point. ■ Splices: These appear as peaks due to signal reflection. Higher peaks indicate poor quality splices.
■ Connectors: These are similar to splices but generally include smaller peaks. ■ Bends: These can cause gradual dips in the trace, with the severity depending upon the bend angle. ■ Breaks: These show up as sudden drops in the trace, indicating complete signal loss.
