Product Description
MOT-31 Multi-Function OTDR Fiber Optic & Network Cable Tester is the ultimate diagnostic companion for telecommunications and network infrastructure professionals. 
Its core strength is its powerful OTDR module, which provides critical insight into fiber health, accurately locating breaks, bends, splices, and measuring overall link loss with a clear graphical interface. The integrated optical tools (OPM, VFL, LS) cover every aspect of fiber installation and maintenance, from measuring signal power and visualizing faults with a red laser to providing a stable light source for loss testing. For copper installations, it performs like a premium cable analyzer, identifying wiring faults, measuring lengths, and tracing Ethernet cables.

Frequently Asked Questions 
Q: Can this OTDR test live fiber?
A: No, this particular model (MOT-31 with 1310/1550nm wavelengths) is designed for testing unlit (dark) fibers only. Testing a live fiber could damage the instrument.

Q: What types of fiber connectors does it use?
A: The tester is equipped with a standard SC/UPC connector interface for all fiber optic tests (OTDR, OPM, VFL, LS).

Q: How do I get the test reports off the device?
A: The tester supports generating reports in PDF and Excel formats. You can use the built-in FTP server function to transfer files to a computer over the network, or physically remove the SD card to access the files.

Q: What is the typical battery life?
A: The built-in 3.7V 4000mAh lithium-ion battery provides several hours of continuous operation, sufficient for a full day of typical field testing.

Customer Feedback
•"Incredible Value for Money. This device replaced three separate pieces of equipment in my toolkit. The OTDR traces are clear, and the VFL is powerful enough to find breaks through the jacket. The cable test features are a huge bonus." — Mark S., Fiber Installation Contractor

•"Perfect for Field Service. The battery lasts all day, and the 4-inch screen is perfect for on-the-go reviews. The event map makes it easy to explain problems to clients. The report generation feature is a professional touch." — Lisa T., Network Field Engineer

•"Saves So Much Time. The IP scanner and PING tools help me quickly sort out network issues before even touching the fiber. The RJ45 length test accurately found a break 200 meters out that would have taken hours to locate otherwise." — David W., ICT Technician

Applications
•Installation, commissioning, and maintenance of single-mode fiber optic networks (FTTH, FTTx).

•Locating and diagnosing faults in fiber optic cables (breaks, bends, poor splices).

•Measuring optical power and calculating end-to-end loss for fiber links.

•Testing and certifying the installation of copper Ethernet (RJ45) and coaxial (BNC) cables.
