Fiber-optic multiplexer FMS converts electrical data signals of 12 devices into light signals and transfers them transparently with low dissipation via optical fiber. At the opposite end, light signals are reconverted into digital signals and transferred to the attached units. The device transfers asynchronous data rates to 128 kbits/sec and supports RS-232, RS-422 and 20-mA interfaces. The unit is suited for troubleshooting cable-sheath damage on singlemode or multimode fiber-optic cables and attains transmission distances to 30 km. Available as a stand-alone unit or for wall-mounting in 19-inch racks, the unit costs $1860, without accessories.
