    VIAVI OLS-34/35/36/37/38 Optical Light Sources

    The VIAVI OLS-3x series consists of small and rugged optical light sources for quick, easy, and convenient field insertion loss measurement and continuity checks.

    Pocket-Sized Light Sources for All Kind of Applications

    SmartPocket™ optical light sources (OLS-3x) are ideal tools to complement the OLP-3x optical power meters for insertion loss and continuity testing in both multimode and single-mode optical fiber networks.

    They offer a dedicated and cost-optimized solution for testing and troubleshooting optical fibers in the field.

    All VIAVI sources are equipped with Auto- λ and Multi- λ functions compatible with any Viavi power meter. This one button operation provides a quick, simple, and error-free testing solution, which makes SmartPocket sources the ideal tools for daily field testing.

    • The OLS-34 covers LAN/WAN access and enterprise multimode networks with 850/1300 nm
    • The OLS-35 covers all standard singlemode telecommunication network applications with 1310/1550 nm
    • The OLS-36 quad-wavelength solution covers both multimode and single-mode wavelengths (850/1300/1310/1550 nm)
    • The OLS-37 is a singlemode source with 3 wavelengths on one port for testing FTTH/PON networks at 1310/1550 nm and 1490 nm
    • The OLS-38 is a singlemode source with 3 wavelengths on one port for testing networks at 1310/1550 nm and 1625 nm
