The Jonard OTDR-1650 Professional Multi-Function 1310/1550/1650 nm OTDR is an all-in-one fiber optic test platform designed for evaluating FTTx infrastructure, measuring single-mode fiber links and locating events that may affect network performance. It combines seven independent modules in a durable, portable instrument suitable for fiber construction, commissioning, maintenance and troubleshooting.
The OTDR-1650 operates at 1310, 1550 and 1650 nm, with a 36 dB dynamic range at each wavelength. It supports G.652 single-mode fiber testing over distances from 500 metres to 100 kilometres. Its filtered 1650 nm OTDR wavelength enables qualified technicians to test compatible live EPON, GPON, BPON and XGS-PON networks without interfering with traffic operating in the filtered 1260 to 1580 nm range.
A large 7-inch colour LCD touchscreen provides a clear interface for configuring tests, viewing traces and evaluating event information. The built-in event map displays fiber events graphically for simplified troubleshooting, while Wi-Fi connectivity and compatible Android and iOS applications allow users to run tests and save results using a smartphone or tablet.

Triple-Wavelength OTDR Testing
The Jonard OTDR-1650 provides Optical Time-Domain Reflectometer measurements at 1310, 1550 and 1650 nm. The 1310 and 1550 nm wavelengths support standard single-mode fiber characterization, while the filtered 1650 nm wavelength provides an additional option for testing compatible live fiber networks.
The instrument also features dual-wavelength testing that allows 1310 and 1550 nm measurements to be viewed simultaneously. Comparing results at both wavelengths can help technicians identify events or conditions that produce wavelength-dependent losses.
A dynamic range of 36 dB at every supported wavelength provides consistent performance across the three OTDR test modes. The available test range extends from 500 metres to 100 kilometres, while pulse widths from 3 ns to 10 µs support measurements across short access links and longer optical routes.
Testing Compatible Live PON Networks
The OTDR-1650 supports live fiber testing by filtering optical signals between 1260 and 1580 nm. The dedicated 1650 nm test wavelength allows qualified technicians to evaluate compatible EPON, GPON, BPON and XGS-PON networks while network traffic is present.
Live network testing requires correct procedures and knowledge of the installed system. Before connecting the instrument, technicians should verify the network architecture, optical power levels, connector type and test port. The 1650 nm function should only be used on compatible live PON systems and according to the equipment manufacturer's instructions.
Short Event and Attenuation Dead Zones
The Jonard OTDR-1650 has a specified event dead zone of 0.5 metre and an attenuation dead zone of 0.5 metre. These short dead zones support the analysis of closely spaced events and near-end fiber conditions in compatible test configurations.
The instrument provides 256,000 sampling points and a stated range accuracy of ±(0.75 metre + sampling interval + 0.0025% of test distance). Loss accuracy is specified at ±0.02 dB/km, and reflection accuracy is specified at ±2 dB.
Graphical Event Mapping
The built-in event map translates OTDR measurement results into graphical representations of detected fiber events. This simplified view helps technicians identify potential connectors, splices, reflections, losses and breakpoints without depending exclusively on interpretation of the complete OTDR trace.
The full trace remains available for detailed analysis, while the graphical event map provides a faster overview during field troubleshooting. This combination supports technicians with different levels of OTDR experience and helps make fiber-link conditions easier to communicate.
Fiber Inspection and Optical Testing
The integrated fiber microscope module supports connector inspection when used with compatible fiber inspection accessories. Inspecting connector end faces before mating can help prevent contamination transfer and reduce the risk of optical performance problems or permanent connector damage.
The instrument also includes optical power meter, light source and visual fault locator modules. Together, these functions provide a flexible platform for fiber continuity checks, optical power measurements, loss testing and visual fault location. Module specifications and connector compatibility should be reviewed before each test.
Wireless Connectivity and Mobile Applications
The OTDR-1650 includes onboard Wi-Fi for transferring results and viewing live test data. Free compatible applications are available for Android and iOS devices, allowing users to run tests and save measurement results using a smartphone or tablet.
A Micro-USB interface is also provided for charging and computer data transfer. Wireless, mobile-device and software compatibility should be confirmed before deployment, particularly when integrating the OTDR into an existing test-data management workflow.
Touchscreen Interface and Data Storage
The large 7-inch colour touchscreen provides room for viewing traces, event maps, test settings and measurement results. The supplied stylus supports accurate operation while helping keep fingerprints away from the screen.
The OTDR-1650 includes 200 MB of internal storage with capacity for up to 4,800 entries. A MicroSD/TF card slot allows external storage expansion. OTDR measurement files use the SOR standard format for transfer and review with compatible analysis software.
Field-Ready Construction
The Jonard OTDR-1650 uses a rubberized hard-plastic enclosure designed to protect the instrument during transportation and field operation. A built-in kickstand positions the screen for convenient viewing on a work surface or at an installation site.
The rechargeable lithium-ion battery supports portable testing away from an external power source. The instrument is supplied with a protective carrying case and adjustable strap for storage and transportation between job sites.
