What is the Fiber Optic Attenuator?
Fiber optic attenuator is a passive device used to reduce the amplitude of a light signal, Used for debugging optical power performance in optical communication system, calibrating and correcting optical fiber instrument, and attenuation of optical fiber signal. Fiber Optic Attenuator classification: 1.In-line Fiber Optic attenuator is a kind of precise device which can provide certain attenuation amount according to engineering needs.The product is used in various optical fiber transmission lines for a predetermined amount of light intensity attenuation; 2.Fixed Fiber attenuator,plug-style(male to female) or buildout style(female to female). Applications: Optical distribution frame, optical fiber network system, high-speed optical fiber transmission system, CATV system, long distance trunk dense Wavelength division multiplexing (DWDM) system, Optical division multiplexer (OADM); 3. Variable Optical Attenuator(VOA), adjustable between 1dB and 30dB. Opelink sells a variety of optical fiber attenuators, including fixed optical fiber attenuators, Adapter-type adjustable optical attenuators, and in-line adjustable optical fiber attenuators, These attenuators are characterized by high attenuation accuracy, low additional loss and good stability.
