Компактный оптический рефлектометр 6418C

6418C OTDR is a mini test instrument designed for FFTx network,mainly used to measure the physical characteristics of optical fibers & cables including length, transmission loss and splice loss etc., can also accurately detect the positions of events and faults along the optical fiber. It's widely applied in the engineering construction, maintenance test, and urgent repairing of optical fiber communication system, as well as R&D, manufacturing, and test of optical fibers & cables.

6418C OTDR deploys an integrative mold of two colors and two materials, which makes it novel and beautiful in appearance, strong and firm in structure. With both touch screen and keypad, the operation is quite convenient. The built-in advanced anti-reflection LCD makes the operation interfaceclearly visible even in the field. The instrument has 4-path of optical interface, which can simultaneously realize the functions of optical power meter, VFL, single-mode and multi-mode test. The interface type is exchangeable, which makes it more convenient to clean the end surface of the fiber. The instrument has multiple external interfaces, can realize not only the remote control via Ethernet interface, but also the data communication with U disk, printer and PC via two different types of USB interfaces. The test result can be sed in the instrument, or to the SD card via SD interface. With large capacity lithium battery, 6418C OTDR can continuously function over 8 hours, very suitable for field work. 

With the automatic measurement function of 6418C OTDR, users can easily conduct the test with no need to know about the operation details. The steps are simple: just connect the fiber, and press 【Start】, then the instrument will automatically set the optimum test conditions and display accurate test results, such as testing curve and event table etc.
PON network test function
6418C is an ideal test instrument for FTTx, with special built-in PON network test function. It can conduct high-precision test on all branches of PON network through 1:8～1:64 optical divider.


Visual fault locator (VFL) function
The built-in VFL function of 6418C has 3 operating modes: CW / 1Hz / 0.5Hz. VFL can rapidly and conveniently find the breaking point or remarkable loss point along the short-distance optical fiber line, so that the maintenance personnel can take steps in short time.
Automatic detection & alarm on the communication light signal
When measuring a fiber line in service, if there is communication light signal in the fiber, the result will be inaccurate, and it may even cause permanent damage to the optical detector in the instrument. 6418C is capable of automatically detecting the communication light signal in the fiber under test once the fiber is connected to the optical connector. If there is a light signal, it will alarm, to provide protection for the instrument in time.
Multiple external interfaces
6418C offers multiple external interfaces as standard configuration, such as USB, Min-USB, Ethernet, earphone and SD interface, which can realize functions as follows:

• Connection with external U disk or SD card;
• Connection with external printer based on USB interface;
• Data communication with PC;
• Remote control via Ethernet;
• Earphone connection is ailable.

TYPICAL APPLICATIONS
6418C OTDR offers three test modes: manual (real-time, erage), automatic, and dead zone.
Manual test mode: manual mode is suitable for skilled operators who are familiar with the instrument, so that to get more accurate test result. In manual test mode, real-time mode or erage mode can be selected based on user's demand.
Real-time test can rapidly detect the dynamic changes of the optical fiber line. It is applied to real-time monitor or to observe the optical fiber connection process and effect.
erage test mode can maximum suppress the noise in the testing curve, so to get a more accurate result. In this mode, the more erage times, the better suppression of the noise, but the longer time it takes. So, in practice, the arage times should be set properly according to necessity.
Automatic test mode: in this mode, the instrument can automatically set the optimized test conditions, and output the test result. There is no need for the operators to know about the complicated background knowledge and the operation details. To enhance the automatic test efficiency, the erage times can be increased properly, though it will prolong the test time.
Dead zone mode: this mode is suitable to test the optical fiber with short distance, for example, to test the jumper length of the optical fiber. In this mode, to get the best result, the reflection loss (or called return loss) of the fiber terminal is required to be larger than 40dB.
