JDSU SWS15101 Tunable Laser

The JDSU SWS15101 is a tunable laser source delivering precise wavelength control across the C-band and extended telecommunications spectrum. Operating as a standalone instrument or integrated into the Swept Wavelength System (SWS), it combines self-aligned optics, single-moving-part mechanics, and all-invar construction for exceptional long-term stability. The front panel interface features keyboard input and rotary control optimized for laboratory use, while analog and digital modulation capabilities extend from DC to 1 GHz. Computer interfaces and analog I/O enable remote operation and seamless system integration.
