JDSU’s SMART optical handhelds go beyond the basics
With more than 70,000 optical handhelds already in use, JDSU continues the success
story with the Smart optical handhelds. The Smart class help your network move to the
next level of performance. JDSU’s Smart optical handhelds encompass a new, intelligent,
and next level product line for testing all optical signals and systems, including broad-
band, PONs, and Gigabit Ethernet.
All of JDSU’s Smart optical handhelds provide:
•An
extended number of calibration wavelengths for the highest performance range in the
industry.
• The SMARTStar graphical user interface for fast, easy, and straightforward operation.
• The SMARTEnergy power supply management system.•
• The SMARTBag for safe and hands-free operation and transport
• Traceable measurements to international standards for confidence in accuracy.
• A robust, shock-proof, and splash-proof design for field operation
• Quick start operation, requiring no warm-up time and reducing testing time.
The
OLA-54 Smart Optical Level Attenuator
is designed for multimode fiber systems
(50/125 µm fiber).
The
OLA-55 Smart Optical Level Attenuator
is a future-proof instrument for system
testing, installation, maintenance, and production of singlemode fibers. Due to mini-
mized differential group delay (DGD), the OLA-55 is also suitable for 40 Gb/s systems.
