In-line Mechanical Variable Type Attenuator
Teosco In-line Mechanical Variable Type Attenuator is a device used to reduce the power level of an optical signal, either in free space or in an optical fiber. The In-line mechanical variable fiber optical attenuator provides a stable attenuation (from 1 to 60 dB) at 850nm/1310nm/1550nm transmission window. They utilize fused fiber to achieve attenuation, providing low wavelength sensitivity, high stability, high return loss and good reliability. This makes our attenuators well suited for EDFA, DWDM and other high-power output applications. These high performance attenuators are compliant with Telcordia GR-910-CORE.
