Fixed in-line optical attenuator is used in optical systems where the optical power from a source is too high for the test equipment in use. It offers a fixed loss that will reduce the source power to an acceptable level. The attenuation level should be stable with temperature and wavelength for a stable reliable system.
T&S provides a wide range of singlemode and multimode fixed in-line optical attenuators. They are used directly on the fiber optic connectors and provide a fixed level of optical attenuation. Single mode fiber based fixed in-line attenuators with single window (1550nm) or dual window (1310nm & 1550nm). Multimode fiber based fixed in-line attenuators with single window (850nm).
