DW-16815 Laser Source can support stable laser signal on many kinds of wavelength, it can identify fiber, test fiber loss and continuity accurately, help to evaluate transmission quality of fiber chain as well. It supplies high performance laser source for field test and lab project development. With features of durable structure, large LCD display with backlight and friendly operation interface, the DW-16815 advanced stability handheld optical light source provides a lot of convenience for your field work. High stability of output power and quite stable output wavelength, it is an ideal instrument for optical network installation, trouble shooting, maintenance and other optical fiber related systems. It can be widely operated for LAN, WAN, CATV, remote optical network, etc. Cooperate with ST800 series Optical Power Meter; it can distinguish fiber, test optical loss and connection, help to evaluate fiber transmission performance.
