Why Use Attenuators?

The ability of any fiber optic system to transmit data ultimately depends on the optical power at the receiver as shown below, which shows the data link bit error rate as a function of optical power at the receiver. (BER is the inverse of signal-to-noise ratio, e.g. high BER means poor signal to noise ratio.) Either too little or too much power will cause high bit error rates. Generally, multimode systems do not need attenuators, because multimode sources rarely have enough power output to saturate receivers. Singlemode systems, especially short links, often have too much power and need attenuators.
Too much power, and the receiver amplifier saturates, too little and noise becomes a problem as it interferes with the signal. Fiber optic attenuators are mainly used for adjusting the Optical Power to a desired level. Attenuators are available in models with variable attenuation or with fixed values from 1 dB to 20 dB or more.

ROLLBALL’S Fiber Optic Attenuators

Fiber optic attenuator is used in the fiber optic communications to reduce the optical fiber power at a certain level. The most commonly used type is female to female (adaptor type), female to male (plug-in type) and in-line type. Adopting advanced attenuation fiber technology, Rollball plug-in and adaptor type fixed value attenuator features high power endurance and low back reflection, suitable for high speed digital transmission and simulated applications. Available in single-mode or multi-mode, FC, SC, ST, LC and MU type.
If the attenuator type you would like to have can not be find on our website, please leave us an email sales@rollball.com.cn. Thanks!
