The Viavi (formerly JDSU) OMK-35V2 is a complete optical loss test kit from the SmartPocket series, combining the OLS-35 dual-wavelength laser source and the OLP-38 optical power meter. Together, these instruments provide a fully self-contained solution for measuring optical insertion loss in singlemode fibre networks — essential for the installation, commissioning, and maintenance of telecommunications infrastructure.

The OLS-35 laser source outputs two wavelengths in a single compact unit, with interchangeable adapter interfaces for compatibility with various fibre connector types. The OLP-38 optical power meter provides accurate optical power readings and is designed to work seamlessly with the OLS-35 for end-to-end loss testing.

Both units are pocket-sized, ruggedly built for field use, and powered by standard batteries, making them ideal for technicians working in the field without access to mains power.
