    VIAVI SmartClass™ OLA-54 and OLA-55

    Optical Level Attenuator

    JDSU SmartClass optical handhelds go beyond the basics

    With more than 100,000 optical handhelds already in use, JDSU continues the success story with the SmartClass optical handhelds. The SmartClass help yournetwork move to the next level of performance. JDSU SmartClass optical handhelds encompass a new, intelligent, and next level product line for testing all optical signals and systems, including broadband, PONs, and Gigabit Ethernet.

    All of SmartClass optical handhelds provide:

    • An extended number of calibration wavelengths for the highest performance range in the
    • The intuitive graphical user interface for fast, easy, and straightforward
    • The intelligent power supply management •
    • The belt bag for safe and hands-free operation and transport
    • Traceable measurements to international standards for confidence in
    • A robust, shock-proof, and splash-proof design for field operation
    • Quick start operation, requiring no warm-up time and reducing testing

    The SmartClass OLA-54 (optical level attenuator) is designed for multimode fiber systems (50/125 μm fiber).

    The SmartClass OLA-55 (optical level attenuator) is a future-proof instrument for system testing, installation, maintenance, and production of single-mode fibers. Due to minimized differential group delay (DGD), the OLA-55 is also suitable for 40 Gbps systems.

    Key features

    • 50/125 μm multimode fiber design (SmartClass OLA-54)
    • Ready for 40 Gbps systems (SmartClass OLA-55)
    • New optical design allowing for low minimum insertion loss
    • Wheel for precise and fast manual setting
    • Absolute and relative attenuation setting
    • FTTx ready
