Versions:
S7FC 1.2.0 is a dedicated instrument-control package released by THORLABS Inc. that provides a unified environment for operating the company’s S7FC1013S Fiber-Coupled Benchtop Semiconductor Optical Amplifier and the S9FC series Polarization-Maintaining Booster Optical Amplifiers. The software combines a full-featured graphical interface, low-level device drivers, and software-development kits for both LabVIEW and C++, giving users the choice of immediate manual control or automated integration into larger experimental setups. Researchers and engineers employ the suite to set pump-current limits, monitor real-time output power, toggle gain-control modes, and log performance data without removing the amplifier from the optical bench. Typical use cases range from stabilizing weak signals in fiber-sensor networks to boosting seed lasers in telecom component characterization, and from extending the reach of OCT systems to serving as a pre-amplification stage in quantum-optics labs. Because the same application binary supports every amplifier model covered, laboratories can standardize on one control front-end even when instruments are swapped or cascaded. The 1.2.0 release is the first and therefore current version, and it ships with digitally signed 64-bit Windows drivers that install automatically when the package is launched. The LabVIEW SDK exposes a palette of ready-to-drop VIs, while the C++ SDK supplies header files and a CMake project that links against a thin wrapper around the manufacturer’s USB HID interface, allowing custom programs to compile under Visual Studio 2019 or later without additional dependencies. The software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always providing the latest build and supporting batch installation alongside other applications.
