Optical Switches
Ultrafast Fiber Optical Shutter/Switch – 1ns
The UFSS is an ultra-fast fiber optical shutter or 1×1 switch based on a semiconductor amplifier, offering a rapid switching speed of approximately 1 ns. It combines low polarization sensitivity, wide optical bandwidth, and a high extinction ratio. Utilizing the gain and absorption properties of a multiple quantum well (MQW) structure, the UFSS provides effective light blocking without introducing reflections, making it ideal for high-performance and precision applications. Designed to handle high gain and signal levels, the UFSS ensures reliable operation at input power levels of 15 dBm or higher. It is housed in an industry-standard 14-pin butterfly package and available with either single-mode (SM) or polarization-maintaining (PM) fiber pigtails, terminated with FC/APC connectors. For PM fiber models, the connector key is aligned to the slow axis.

System integration
Integration and compatibility
Use these checks to connect Ultrafast Fiber Optical Shutter/Switch – 1ns 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: SM28, PM1550, PM1310 · Fiber Buffer: 0.9mm Tube
- 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: 1550nm, 1310nm
- Check the Optical Switches 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: Non, Benchtop, Module, Kit
- 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.
