Variable Fiber Optical Splitter/Coupler

SKU: NSVS, NHVS

The Variable Fiber Optical Splitter/Coupler splits an incoming optical signal among the two output optical fibers (1×2) with a continuously variable ratio controlled by an input voltage signal from 0 to 5V, either DC or AC. Two inputs/outputs (Full 2×2) configuration is also available. The device does not create extra loss during the transition and is bidirectional. When the electrical control signal is removed, or at 0 V, the splitter returns to the original ratio of 100:0. The all-solid-state crystal design meets the most demanding requirements of ultra-high reliability, fast response time, and continuous operation over 25 years. The Variable Fiber Optic Splitter has passed Telcordia and space reliability qualification tests.
The unit is mounted on a driving board with a control signal input SMA connector and a wall plug-in power supply. Several frequency versions of drivers are available. As an Electro-optical crystal-based device, the variable splitter output has a certain degree of variation due to environmental changes. A driver with output power stabilization via feedback control is available as a Precision Variable Fiber Optical Splitter.
For 2×2 splitters, the splitting for the two inputs is related but functions simultaneously. One can set the ratio of the first input and then measure the splitting ratio of the second input while turning off the first one.
