Overview
GAOTek Variable Optical Attenuator (VOA) is an important optical passive device in optical fiber communications, through the attenuation of the transmitted optical power to achieve real-time control of the signal, can be used with optical wavelength-division multiplexer (WDM), splitter detector (TAP PD), erbium-doped fiber amplifier (EDFA), and other optical devices constitute the ROADM, VMUX, gain-flattening EDFA and other modules, but also can be used directly in the optical receiver’s Overload protection
