A JDSU (now VIAVI) Light Source, such as the SmartPocket series (e.g., OLS-35), is a rugged, handheld device designed to test fiber optic networks by emitting stable laser light at specific wavelengths. These sources are used in combination with an optical power meter to measure fiber insertion loss and check for continuity, featuring Auto-λ function for automatic wavelength detection and multiple-wavelength outputs for compatibility with both singlemode and multimode fibers. They are pocket-sized, easy to operate with simple controls, and are powered by AA batteries or USB, making them ideal for field maintenance. JDSU Optical Light Source is a handheld fiber optic testing device used to generate stable optical signals for testing fiber optic cables and networks. It is commonly used with an optical power meter to measure insertion loss and check fiber link performance. The device supports multiple wavelengths and is suitable for both single-mode and multimode fiber testing. Compact design and easy operation make it ideal for field maintenance and network installation.
