XQ5110 is a high-stability single mode test light source which is designed by OSCOM Technology. It utilizes DFB/LD laser as its emission source, and integrates the technology of automatic temperature control (ATC), automatic power control (APC) and RS232C communication control, etc. It can provide 1/2/3/4-channel benchtop light source, and its typical application wavelengths are 1310nm, 1490nm, 1550nm, 1625nm, 1650nm, etc. Besides, depolarization processing can be added as needed to provide low polarization output. XQ5110 is stable, reliable, easy to use and very suitable for optical device testing and other applications.
