Fixed in Line Attenuator
Fixed in line attenuators are used in optical systems where the optical power from a source is too high for the test equipment in use. The fixed optical fiber attenuator introduces an in-line fixed loss that will reduce the source power to an acceptable detection level. The attenuation level should be stable with temperature and wavelength for a stable reliable system.
LFO provides a wide range of Fixed in-line singlemode and multimode Attenuator. They are used directly on the fiber optic connectors and provide a fixed level of optical attenuation. Single mode fiber based attenuators with single window (1310nm or 1550nm) or dual window (1310nm & 1550nm). Multimode fiber based attenuators with single window (850nm or 1310nm). FC and SC connector types with PC or APC polish are available, as well as ST and LC types of attenuators.
