The VIAVI OLS-3xV2 series consists of small and rugged optical light sources (OLS) for quick, easy, and convenient field insertion loss measurement and continuity checks. SmartPocket V2 OLS are ideal tools to complement the OLP-3xV2 optical power meters for insertion loss and continuity testing in both multimode and single-mode optical fibre networks.

They offer a dedicated and cost-optimized solution for testing and troubleshooting optical fibres in the field. All SmartPocket V2 sources are equipped with Auto-λ and Multi-λ functions compatible with any SmartPocket V2 power meter. This one-button operation provides a quick, simple, and error-free testing solution, which makes SmartPocket V2 OLS the ideal tool for daily field testing.
