OLS-34 Optical Light Source | Multi-mode

The OLS-34 is used specifically for LAN/WAN access and enterprise multi-mode fiber optic networks with 850/1300 nm wavelength, it also has fixed ST and LC adapters, and switchable FC, SC, ST and LC adapters. OLS-34 optical light source is small, shock resistant, water splash resistant and can be powered by Micro USB and AA batteries, for 30 hours. SmartPocket small and rugged optical light source VIAVI OLS-34 is used with power meters for testing loss and continuity in fiber optic networks.
