Double/Quad Light Source Insertion Loss Instrument Return Loss Tester
Return loss instrument, multi-functional high-precision optical communication test instrument. It is widely used in the insertion loss, return loss and stability measurement of optical fiber and cable, optical passive devices and optical fiber communication systems. Can be used for manufacturers device testing, research institutions research and development and engineering construction and maintenance of the test instrument.
U8523 dual light source plug back loss instrument is a benchtop, LCD display, single light source outlet (FC/APC adapter), measuring power plug loss, back loss and direct measurement of optical power instrument. The instrument is suitable for the test of optical communication components, installation inspection, especially the measurement of connection plugs of light cables. Any two fixed wavelength light sources can be built into the system.
Instrument features:
(1) High test accuracy
(2) Wavelength synchronous switching
(3) A variety of working modes
(4) Simple and convenient operation
(5)Power meter probe built in
