A fiber optic attenuator, otherwise known as an optical attenuator, simulates the loss which may be the result of long time fiber. A significant characteristic of an effective fiber attenuator is they shouldn't reflect light, instead, they ought to absorb any additional light without having to be damaged. Ever since the light power utilized in fiber optic communications are fairly low, they sometimes might be absorbed without noticeable destruction of the attenuator itself.
Fiber optic attenuator is utilized during the fiber optic communications to reduce the optical fiber power with a certain level, essentially the most common type is female to male plug type fiber optic attenuator, it has the fiber connector at the reds and also an opposing side may be a female type fiber optic adapter, fiber optic attenuator name is dependent on the connector type and the attenuation level. Variable optical attenuators can come with a number of designs. They are really general used by testing and measurement, in addition, they employ a wide usage in EDFAs for equalizing light power among different channels. Connector type attenuator resembles a bulk head fiber connector, fantastic male end as well as a female end. It mates to regular connectors the exact same type for instance FC, ST, SC and LC.
FiberStore supply variable fiber optic attenuator FC, SC/APC, ST, PC, LC, UPC, MU, FC/APC, SC, LC/APC, fixed value plug type fiber optic attenuators with various attenuation level, from 1dB to 30dB.
For example, optical variable attenuator is actually a double window (1310/1550nm) of passive components. The variable optical attenuator could continually and variably attenuate the light intensity in the optical fiber transmission. Variable fiber optic attenuator can help simulate distance or actual attenuation in the fiber optic testing work by inserting a calibrated attenuation inside the link. When using the variable fiber optic attenuator, technicians could verify the electricity margin received by testing the fiber optic link power budget. Variable fiber attenuator might help user vary the sunshine power injected with a source of light on the optical fiber. Important parameter of variable fiber attenuator include its insertion loss, reflection loss and attenuation range.
LC fiber optic attenuator contains two kinds which are usually UPC and APC, to suit for the according LC connectors. LC UPC fiber optic attenuator return loss might be more than 55dB, LC APC fiber optic attenuator return loss might be more than 65dB. Working range of the LC fiber attenuator is 1240nm to 1620nm, such as the typical 1310nm and 1550nm single mode applications. There're constructed of the best materials as well as every piece is tested during production. The Lc fiber optic attenuator is commonly employed with fiber amplifier, DWDM and telecommunications equipment.
