Nettest - CMA 4500 Optical Time Domain Reflectometer

Combining the technology of the industry leading CMA4000 OTDR with the CMA5000 Multi-Layer Test Platform makes the CMA 4500 the Next Generation in OTDR Testing.
Based upon NetTest's leading OTDR technology and its advanced CMA5000 Multi-Layer Test Platform, the CMA 4500 takes fiber installation, maintenance and documentation of the network to the next level. Designed to provide exceptional performance at a price that fits most budgets, it's the ideal tool for Metro, CWDM, ultra-long haul and PON based, fiber-to-the-premise (FTTP) deployments.

Featuring an intuitive and user-friendly GUI, a powerful, Windows operating system, a large, high resolution color display with touch screen interface and rugged casework, the CMA 4500 can cover any testing requirements from single mode to multimode, from 10 meters to 250Km. Sophisticated analysis software then provides consistent and accurate fiber characterization automatically or with the press of a button. USB ports, a 10/100 Ethernet interface, modular I/O drives and dedicated testing modes further ensure unparalleled ease of use and flexibility.

As an added value, the CMA 4500 can be equipped with a stabilized light source, power meter and a Visual Fault Locator (VFL) that enables users to visually locate breaks within central offices and quickly identify specific fibers within a cable or splice tray. An available connector inspection microscope further reduces costly troubleshooting of connector related issues by quickly pinpointing the source of the problem, all without any of the risks associated with conventional microscopes.

Dedicated testing modes designed specifically for the task at hand.
Working in Fault Locate Mode, the CMA 4500 is ideal for reel testing or continuity verification. It allows you to quickly and easily identify faults, all at the touch of a single button. A built-in connection check verifies proper fiber connection and thus, completes fiber characterization in a matter of seconds.

Designed for fiber installation and commissioning, the CMA4500's Construction Mode automates frequently performed tasks, eliminating common user errors such as incorrectly named or missing traces. It allows users to test, analyze and save multiple wavelength traces with the touch of a single button.

The CMA 4500 Standard OTDR features the ability to manually set all, some or none of the testing parameters, providing unsurpassed parameter optimization. Key parameters such as wavelength, pulse width, range/resolution and averaging mode can easily be set via the CMA4500's touch screen or dedicated hard key interfaces. The Standard OTDR's ability to overlay up to eight traces simultaneously, four display options and user selectable loss modes ensure that a user has all the tools needed to test their network
