Couplers, Splitters & Combiners
Variable Fiber Optical Splitter/Coupler
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.

Prefix: NSVS · Type: 1x2 · Wavelength: 1060nm · Driver: 20kHz · Configuration: Single-stage & ≤ 0.5W · Fiber Type: SMF-28 · Fiber Cover: Bare fiber · Fiber Length: 0.25m · Connector: FC/PC
System integration
Integration and compatibility
Use these checks to connect Variable Fiber Optical Splitter/Coupler to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- Fiber Type: SMF-28, HI1060, HI780, PM1550, PM980, Special · Fiber Cover: Bare fiber, 900um tube, Special
- Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
- Wavelength and loss budget
- Wavelength: 1060nm, 1310nm, 1550nm, 1625nm, Special
- Check the Couplers, Splitters & Combiners passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
- Control interface
- Driver: 20kHz, 100kHz, 500kHz, 1MHz, No Drift, Special
- Match supply voltage, analog or digital command range, connector pinout and default optical state to the instrument interlock. Confirm the unpowered state explicitly — it decides what happens to the link on a power failure.
