Fiber multiplexer

The FM-1600 fiberoptic multiplexer is a remote-controlled two-pole eight-position fiber switch that is designed for use in FTIR spectroscopy. The device allows the user to insert one of eight different sensors or optical circuits between the optical source and the FTIR spectrometer. The multiplexer switches both ends of the optical path, eliminating spurious spectral distribution problems encountered when using fiberoptic bundle source distribution to a sensor array. The device uses 200- to 600-µm core fiber with less than 1-dB insertion loss (excluding connectors).
