Precision Variable Fiber Optical Splitter

SKU: PVST

The Precision Variable Fiber Optical Splitter maintains a constant splitting ratio between the two output fiber ports, regardless of fluctuations of input power and environmental conditions. The splitting ratio can be varied with a control voltage of 0-5V at a fast speed, in which 0V means 100% passing through one port and 5V means 100% passing through another port, respectively. This is achieved by integrating two tap detectors at the two fiber outputs of a 1×2 NanoSpeed™ switch and locking to the ratio using a feedback closed-loop circuit. The splitting is proportional to the 0-5V control signal. The non-mechanical device has passed the most stringent mil-spec and space flight qualifications and is designed for over 20 years of continuous operation. The module comes with a wall-plug 12V power supply.
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.
