fiber optic attenuator, FC fiber attenuator,fixed plug-in fiber attenuator
Sometimes in the fiber optic network ,people may need to reduce or balance the power of the light transmitted from one device to another device ,fiber optic attenuators are used in such cases, they are able to control the output of the fiber light power level.Fiber optic attenuator are used for reducing the power of the light in the fiber optic network.we supply several types fiber optic attenuators, fixed value fiber optic attenuator refer to the attenuator that can reduce the power of fiber light at a fixed value loss, for example, 2dB. While adjustable fiber optic attenuator refer to the attenuator that can generate a adjustable Loss to the fiber optic link. our fiber attenuator series include:SC ,FC,LC,ST ,MU,SC/APC ,FC/APC,single mode fiber optic attenuator and multimode fiber optic attenuator available.Our fiber optic attenuators are manufactured according to international standard and are compartible with the fiber optic products currently available in the international market.
Fiber optic attenuators can be designed to use with various kinds of fiber optic connectors. the attenuators can be female to female which is called bulkhead fiber optic attenuator or male to female which is also called a plug fiber optic attenuator.bulkhead and plug types are designed without cables, another type inline fiber optic attenuator is designed with a piece of fiber optic cable.
Fixed Value Fiber Optic Attenuators
Fixed value fiber optic attenuators have fixed values that are specified in decibels. Their applications include telecommunication networks, optical fiber test facility, LAN and CATV systems. Fixed value fiber optic attenuators are composed of four groups: Fixed Plug in Fiber optic attenuator, Fixed Standard Adapter Fiber optic attenuator , Fixed In-line Fiber optic attenuator, and Fixed Hybrid Adapter Fiber optic attenuator.
Fixed Plug in Fiber Optic Attenuator has a male end and a female end.
Fixed Standard Adapter Fiber Optic Attenuator (bulk head type) has a female end and a female end.
Fixed In-line Fiber Optic Attenuator has a fiber cable terminated with two connectors which you can specify types.
Fixed Hybrid Adapter Fiber Optic Attenuator has a female end and a female end with different kind.
Variable Fiber Optic Attenuators
Variable Fiber Optic Attenuators come with many different designs. They are general used for testing and measurement, but they also have a wide usage in EDFA for equalizing the light power among different channels. Variable Fiber optic attenuators are composed of three groups: Variable plug in type, Variable adapter type, Variable In-line type and Manual VOA type:
Variable Plug in Fiber Optic Attenuator has a male end and a female end.
Variable Adapter fiber Fiber Optic Attenuator (bulk head type) has a female end and a female end.
Variable In-line Fiber Optic Attenuator and Manual VOA Fiber Optic Attenuator are with more accurate attenuation compared with traditional connector type fiber optic attenuators, this fiber optic attenuator is with a precision screw set, by turning it, the attenuation range can be varied and this fiber attenuator can be with various terminations on the each side of the cable.
Fiber optic attenuator data
