Product Detail

FW8422 Optical Time-Domain Reflectometer (OTDR)

Product Overview

FW8422 OTDR can used to test single-mode wavelengths of 1310nm, 1550nm, 1490nm, 1625nm and 1650nm, multi-mode wavelengths of 850nm and 1300nm as well as customized special wavelengths. It provides multiple optional modules, such as single wavelength, multi-wavelength and online test. With the maximum dynamic range of up to 50dB, the device can be used for remote multi-branch communication network test. It's designed with a minimum event dead zone of0.5mwhich makes the near connection easy to be supervised, and the lowest sampling resolution of2.5cmwhich enables it to locate the event point accurately. Additionally, the device is also designed with multiple convenient functional options, such as stable light source, optical power meter, visible red light source and fiber end face inspection tester.

FW8422 OTDR is designed with an operating temperature and a storage temperature of-10℃~50℃and-40℃~70℃respectively to meet both EMC requirements as well as vibration and shock test requirements, a MTBF(θ0) of 6000h or above to ensure a high reliability, and a 75W built-in Li battery to ensure an endurance for continuous measurement in the wild field.

Rapid automatic test

Due to the automatic test function of FW8422, it's not necessary for the user to know more about its operation. Connect the optical fiber and press the [Test] button. Then, the device will set the optimum test conditions automatically, and finally output accurate test results, such as the test curve and the list of events.

Optical Time-Domain Reflectometer (OTDR)

Unique PON network test

As an ideal tester of ODN and FTTx, FW8422 is provided a unique built-in PON network test function, can penetrate an optical splitter of up to 1:128, and can be used to test each branch of the PON network accurately.

Automatic monitoring and alarm of incoming optical signals

When the OTDR is testing the optical fiber line, the optical communication signal in the optical fiber, if any, will lead to inaccurate test results and even unrecoverable damages to the detectors in the device. FW8422 can monitor the optical communication signal in the optical fiber under test automatically. As long as the optical fiber under test is connected to the optical interface of FW8422, the device can automatically sense and monitor whether there is optical communication signal in it. Once an optical signal is monitored, it will prompt an alarm in time, so as to provide the quickest and the most timely protection for the device.

150GHz 32CH DWDM MUX DEMUX DUAL FIBER LC/UPC 1U Rack

150GHz C-band Flat top 32-Channel Athermal AWG, DWDM MUX DEMUX LC/UPC 1U RACK Introduction The 150GHz 32ch DWDM MUX DEMUX operate in C-band. And it meet the following specification over the operating temperature. Definition Note: All specifications should be guaranteed at the worst-case polarization state and over the entire operating environmental condition and end of life. The Insertion Loss of a device is defined as the maximum loss at a defined wavelength, taking into account the worst-case polarization state over the full operating temperature range. The Insertion Loss Uniformity of a device is the difference between the insertion loss of the best-case and worst-case channels. The Polarization Dependent Loss of a device is the maximum insertion loss difference between all polarization states at the defined wavelength. The Reference Passband is defined as a band of wavelengths around each center wavelength. It is used in the definition of crosstalk. The Adjacent Isolation of channel is the maximum insertion loss difference from the mean transmission at the ITU grid wavelength to the highest power over the all polarization and the ITU band of two adjacent channels. The Non-adjacent Isolation of channel is the maximum insertion loss difference from the mean transmission at the ITU grid wavelength to the highest power over the all polarization and the ITU band of the non-adjacent channels. The Total Crosstalk of channel is the total cumulative insertion loss difference from the mean transmission at the ITU grid wavelength to the highest power over the all polarization and the ITU band of all other channels including adjacent and non-adjacent channels. The Wavelength Accuracy is defined as the maximum difference between the defined wavelength and the center of measured 3dB passband.
