Description
The Fluke Networks SFSINGLEMODESOURCE SimpliFiber® Pro Singlemode 1310/1550 Laser Light Source is a high-performance fiber optic testing solution designed to simplify and speed up singlemode network certification, verification, and troubleshooting. Featuring a single-port, simultaneous dual-wavelength capability, it completes tests in half the time by recording measurements from both wavelengths in a single pass.
Built to work seamlessly with the SimpliFiber Pro Optical Power Meter, this light source supports additional wavelengths (1490 and 1625 nm) to cover a wider range of applications, including FTTx deployments. Its rugged, ergonomic design ensures durability in field environments, while user-friendly features like auto-wavelength detection, FindFiber™ Remote ID, and CheckActive™ streamline testing for faster, more accurate results.
Whether you're verifying optical loss, locating faults, or preparing detailed reports via LinkWare™ Cable Test Management Software, the SFSINGLEMODESOURCE delivers unmatched efficiency and reliability for professional fiber optic technicians.
