Description Parameters Company Profile Related product
LC-LC Variable Optical Attenuator (VOA) is an important optical passive component in optical fiber communication. It can realize
real-time control of signals by attenuating the transmitted optical power. The variable optical attenuator can be combined
with optical components such as optical wavelength division multiplexer (WDM), spectroscopic detector (TAP PD), and erbium
doped fiber amplifier (EDFA) to form ROADM, VMUX, gain flat EDFA, etc. Overload protection of the optical receiver.
