GQ-390A Benchtop return loss tester

return loss tester Description GQ390A Insertion Loss/Return Loss Test Station is a high performance loss test station that is designed specially for Optical Passive Components production Test and Lab Test.It combines three different working modes as a return loss meter, optical power and loss meter and a stable laser source in one test station.It features: "Outstanding measurement accuracy and repeatability With built-in optical isolators in the lasers, with the most advanced microelectronics technology and high quality optical devices, and incorporated well-designed built-in software, to ensure the test station has a high stable output power, quick testing speed and wide measurement range." "Automatic wavelength setting with synchronization In return loss test model, the optical laser source and optical power meter are at the same measurement wavelength simultaneously. In optical power meter model, measurement wavelength can be set separately." "Multiple working modes Three working modes in one test station: Return loss test, optical power and loss test and stable laser source." "Human Engineering Design Comfortable appearance outline, using high quality metal case, to avoid electrical interference caused by production conditions. Attractive and durable Press-button with a perfect handle sense. Equipment holder can be adjustable to satisfy the various applications, meet the Human Engineering requirements. " "Dustproof and active Optical Interfaces, easy removal for clean and replacement Active interface be used in both laser source and power meter, easy to remove to clean Optical interface adaptors and photo detector or replace other types adaptors, such as FC/SC/ST/2.5mm universal/1.25mm universal/MT-RJ etc. so that to be used in various types patch cords.
