LC UPC Flanged Fiber Optic Attenuator Singlemode Fixed Female to Female 1~25dB

●Products Description:

Fiber Optic Attenuator, is a device used to reduce the power level of an optical signal, either in free space or in an optical fiber. The basic types of optical Attenuator are fixed.

● Advantage & Application:

► Low insertion loss and back reflection loss;

► High Precision of Mechanical Dimensions;

► Compliant with Telcordia GR-326-Core, IEC, TIA;

► 100% Optic test;

► Compartmentalized case provides safe component storage and simple organization;
► RoHS compliant.

● Does Multimode or Single-mode Systems need attenuators?

Generally, multimode systems do not need attenuators. Multimode sources, even VCSELs, rarely have enough power output to saturate receivers. Single-mode systems, especially short links, often have too much power and need attenuators. For a single-mode applications, especially analog CATV systems, the most important specification, after the correct loss value, is return loss or reflection! Many types of attenuators (especially gap loss types) suffer from high reflection, so they can adversely affect transmitters just like highly reflective connectors.

Choose a type of attenuator with good reflectance specifications and always install the attenuator ( X in the drawing) as shown at the receiver end of the link. This is because it's more convenient to test the receiver power before and after attenuation or while adjusting it with your power meter at the receiver, plus any reflectance will be attenuated on its path back to the source.
