SKYSHL 1310nm+1550nm 32dB+30dB SM OTDR Fiber Testing

An Optical Time Domain Reflectometer (OTDR) is an important instrument used by organizations to certify the performance of new fiber optics links and detect problems with existing fiber links.

With the rapid advancements in fiber optic technology, OTDR testing methods have become indispensable to building, certifying, maintaining and troubleshooting fiber optic systems.

SKYSHL provides a new Optical Time Domain Reflectometer(OTDR)–SS313T series. They are used to measure the fiber length and overall optical attenuation in a circuit. The analyzed data provides insight into the integrity of the fiber and any passive optical components (such as connectors, splices, splitters, and multiplexers) transmitted along the cable path.

SS313T-2A(1310nm+1550nm 32dB+30dB) SM OTDR Key Features:

  • Mutiwavelengths: 1310nm+1550nm/32dB+30dB(Max Testing Distance:120km/75mi).
  • Built-in Event map, Visual Fault Locator, Optical Power meter(800-1700nm/-50~+26dB) and Optical Light Source(OLS-1310nm+1550nm) function.
  • One touch operation, automatic analysis, and tailored OTDR user interface for different skill level.Very short Event dead zone(0.8m) and Attenuation dead zone(4m).
  • Realtime measuring function, convenient to monitor the splicing process.
  • The 7-inch capacitive touch screen makes the operation more sensitive.
  • Internal -5dBm stable laser source;SS313T Complete interface accessories: SC, ST, FC, LC UPC&APC adapter.
  • The warning function can prevent the optical signal from damaging the OTDR module.
  • Integrated with 2 main USB and one sub USB port, for controlling by PC or connect external instrument.
  • Support Chinese, English, Spanish, German, French and Portuguese, friendly interface, analog keyboard capable.
  • The trace file/test curve can be kept in .sor format for the analysis software to process, analyze and print the test report.

Intelligence OTDR

The Auto test lets you take advantage of the full power of your OTDR—bringing automation to a new level and enabling untrained technicians to become test experts in no time.

With one click, the unit automatically performs link recognition, sets the optimal parameters and launches multiple acquisitions and analyses—at multiple wavelengths—consolidating the results obtained for every link section and every network element. Get accurate information right away on each link element and export it to a single report.

OTDR Test Curve and Event Type

A picture is worth a thousand words, and the OTDR picture (or “trace”) takes a lot of words to describe all the information in it!

The slope of the fiber trace shows the attenuation coefficient of the fiber and is calibrated in dB/km by the OTDR. Connectors and splices are called “events” in OTDR jargon. Both should show a loss, but connectors and mechanical splices will also show a reflective peak. The height of that peak will indicate the amount of reflection at the event.

Reflective pulses can show you the resolution of the OTDR. You cannot see two events closer than is allowed by the pulse width. Generally longer pulse widths are used to be able to see farther along the cable plant and narrower pulses are used when high resolution is needed, although it limits the distance the OTDR can see.

Built-in OTDR OPM OLS and VFL

SKYSHL SS313T-2A combines all essential fiber tests in one handheld with Optical Time Domain Reflectometer(OTDR-1310nm+1550nm/32dB+30dB),visual fault locator (VFL-Max test distance 10km), optical power meter (OPM-850-1625nm/-50~+26db), and Optical Light Source(OLS-1310nm+1550nm).

Event Map

The OTDR optical fiber test is simplified through the event map, and the representation accuracy of the network topology is optimized through intelligent algorithms, and all network components and fault locations are dynamically located and identified at the maximum resolution, thereby bringing a new experience to the optical fiber test engineer .
