Fiber Optic attenuators are used to reduce the optical power level of a communication signal, in an optical fiber used in a fiber optic communication link. They use different principles of functioning like gap-loss, absorptive or reflective techniques.Three basic types of fiber optical attenuators are step wise variable,continuously variable and fixed.
Fixed value fiber optic attenuators have fixed values that are specified in decibels.Their applications include telecommunication networks, optical fiber testfacility, LAN and CATV systems. Fixed value fiber optic attenuators are composed of four groups: fixed-plug in type, fixed adapter type, fixedIn-line type, and fixed hybrid adapter type.
GoodFtth is providing wide variations of high quality fixed plug-in, fixed adapter, fixed In-line, variable plug-in, variable adapter, variable In-line and manual VOA fiber attenuators.Please reach us for details.
