🏅9 AND 1 FEATURES
SKYSHL SS306T fiber OTDR tester contains 9 functions: OTDR [ SS306T-2A ( 1310nm/26dB + 1550nm/24dB ) | SS306T-1A ( 1610nm/26dB ) ], Event map, Fiber end inspection (Exclude, Optical function), OPM [ OPM-800~1700nm / -50 ~ +26dB ( -70 ~ +6dBm Optional, Please contact us if needed) ], VFL (650nm±20nm / 10mW), OLS and optical power loss test ( Same wavelength as OTDR ), RJ45 cable sequence tester ( >3km ) and RJ45 network cable tracker.
🏅EXTREME BLIND ZONE-EDZ (1.6 M) + ADZ (8.0 M)
The SS306T uses state-of-the-art optical technology and analysis algorithms to provide users with very short event blind zones (SM of 1.6m) and attenuation blind zones (SM of 8.0m), thus providing a solution for detecting faults over short distances. (Since the pulse width affects the size of the blind zone, a narrow pulse width is recommended for adjacent events, while a wide pulse width is recommended for measuring the far end of the fiber.)
🏅AUTO OTDR + EVENT MAP FUNCTION
SKYSHL SS306T provides a series of automation functions, among which the automatic test mode greatly simplifies the test process, urgently requiring the user to set the test wavelength and test time to complete the test, no longer need to set up more test parameters, even if unfamiliar with the user can become an expert in testing. In addition, the SS306T provides an event graph function that simplifies the test events (splices, connectors, macrobends, breakpoints, attenuators, etc.) into graphs, which provides great convenience for users to analyze the problems.
🏅COMPATIBLE WITH APC & UPC SC+ST+FC+LC CONNECTORS

OTDR Test Curve and Event Type
Test Curve
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.

If you need to test multimode fiber, please purchase SS313T, SS315T, SS322T series OTDR.
2.What is the difference between SS306T-2A and SS306T-1A?
SS306T-2A and SS306T-1A have different wavelengths and dynamic ranges, SS306T-2A provides two singlemode wavelengths-1310nm/26dB and 1550nm/24dB, SS306T-1A provides one The SS306T-2A offers two single-mode wavelengths-1310nm/26dB and 1550nm/24dB, while the SS306T-1A offers one wavelength-1610nm/26dB, both of which can only test single-mode fibers.
3.Can the SS306T test multimode fiber?
No. SS306T only has the wavelengths of 1310nm,1550nm and 1610nm for testing single-mode fiber, and if you need to test multimode fiber, you need to use the wavelengths of 850nm or 1300nm, so the SS306T does not support the testing of multimode fibers, if you need to test multimode fibers, please purchase the SS313T, SS315T or SS322T series OTDR.
4.Can the SS306T test PON networks in-line?
Yes, SS306T-1A provides 1610nm wavelength with optical filter, it can test PON network without stopping the network, which is more convenient for testing. If you use SS306T-2A, you have to stop the network work before testing, otherwise it may lead to wrong test results or even damage the equipment.
Therefore, if you need to test the PON network on-site and online, please choose to purchase the SS306T-1A.
5.What is the difference between Auto OTDR mode and Expert OTDR mode?
Auto OTDR Mode: No need to set too many parameters, only need to set the test wavelength and test time, the test can be completed with one click, the OTDR will automatically complete the parameter setting and display the test results, it is very easy to use and saves time and effort. This mode can meet most of the challenges of fiber optic testing, for beginners or testing unknown fiber links, this mode will be the best assistant.
Expert OTDR Mode: Users who are not satisfied with the automatic mode or are very familiar with fiber optic testing can set up various parameters for the test according to actual needs, such as test range, attenuation pass/fail thresholds, event display thresholds, pulse width, etc., in order to meet the requirements of fault detection and fiber optic link certification.
Usually these two test modes are used in combination with each other, and different test modes are used in different scenarios. Of course, if you have any questions in the test, you can contact us, our expert team promises to respond to any of your questions within 24 hours.
