Fiber Optic Attenuator By Andeve Tech Limited

Fiber optic attenuator, for a fiber optic receiver, too much light can overload it and degrade the bit error ratio. In order to achieve the best bit error ratio (BER), the light power must be reduced. Fiber optic attenuators fit the requirement perfectly. This can happen when the transmitter delivers too much power such as when the transmitter is too close to the receiver.

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.

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.
