FMX - Fiberoptic Multiplexer for max. 10 to 16 Channels



Request for information



The FMX-Series Multiplexer is designed to simultaneously switch the fiber-optic input (source) and fiber-optic output (detector) signals between 2 to 16 channels (depending on the selected model). That means, the FMX Series multiplexers allow a single spectroscopic instrument with fiber-optic coupling to be switched between up to 16 different sampling devices. Channels can be easily added up to the unit’s capacity by users in the field.

FMX-100 units (mono-directional) can also be easily expanded up to their respective capacity (10 channels), or converted to bi-directional units. A properly installed unit can be expected to provide accurate and repeatable optical switching over a long service life. The FMX series allow a choice of popular data processing protocols (ASCII protocol and OPTO-22 instruction protocol). Optionally the FMX can be controlled by the FMC-020 as shown in the picture.

The FMX fiber-optic Multiplexer has an excellent channel matching and high transmission. The multiplexer is coupled via SMA (or optional FC) connected single core fibers between 400µm and 600µm core diameter.
