They feature a rugged design, built to withstand the difficult testing environment of fiber optic cable installation and maintenance. A large LCD display and a dual-way powering system including a 9V battery and an optional power adapter, ensure the CMA5 Series will adapt to any situation. With no warm up time, fast response time, auto-zeroing capabilities and tone detection, the CMA5 Series helps reduce measurement time.

The CMA5 Power Meters are ideal for testing single-mode and multimode fibers in various types of applications, thanks to multiple wavelength calibration at 850/1300 nm for datacom testing needs, 1310/1550/1625 nm for all WDM testing, as well as 1490 nm for FTTx testing needs.
