2/3/4/5 Multiwavelength Loss Recovery Instrument Back Reflector
U8523B+U88201 1310/1550 nm dual light source back reflectometer/power meter is a benchtop, LCD screen display, single light source outlet, measuring back loss, insertion loss and direct measurement of optical power instrument. Used to measure the reflection attenuation of various optical devices and optical links, control the quality of optical fiber connectors, optical communication components, systems, optical fiber and cable plug measurement, is applied in the field of excellent solutions.
The U8523 has a built-in light source of 1310nm/1550nm. Integrated with FC/APC ultra-low back reflection connectors at the output port, hybrid jumpers can be used to accommodate measurements of various connector types without affecting the return loss measurement range. When the device under test (DUT) is connected to the jumper DUT output terminal, the return loss of the device under test is displayed.
Display interface introduction
Initialization interface
When the U8523 dual light source is plugged back into the loss instrument and powered on, the display screen will display some detection information, including host serial number and firmware version, as shown in the figure below:
