Sold as pictured. Includes GN Nettest CMA 4000i with CMA 4476 singlemode module. The 4476 module includes 1550/1625nm 40/40 source and power meter.

The CMA4000i Optical Test System is an all in-one test and measurement solution for network commissioning, fault location/restoration, maintenance and DWDM spectral analysis. Combining best in class OTDR and OSA performance, modular flexibility and ease-of use, the CMA4000i is the ultimate time saving system for increasing network performance while reducing the cost of measurement.

The All-In-One System CMA4000i can be configured as an  Optical Time-Domain Reflectometer (OTDR) with a Visual Fault Locator (VFL), Optical Power Meter and Light Source, or as a high resolution Optical Spectrum Analyzer (OSA) for DWDM systems. With its variety of functions, the CMA4000i clearly offers the best value for optical network installation, commissioning and maintenance applications.

The Nettest 4000 series OTDR is a great choice for testing and maintaining all your fiber optic lines. It offers all thefeatures of a mainframe OTDR in a rugged, field portable unit. The dead zone and dynamic range performance of the CMA4000 is outstanding and fully configurable. If you are looking for a fast reliable OTDR the CMA4000 should be your first choice.

The CMA4000

When it comes to fiber optic testing, time is money. That's why we designed the Communications Media Analyzer CMA4000. It offers all the features of a mainframe OTDR in a rugged, economical, field-portable unit and its unique features make it better than other OTDRs. Intelligent software minimizes necessary steps to perform frequent functions, its multi-tasking ability allows the CMA4000 to test, analyze and display data faster than any other OTDR available. Plus, it has incredible deadzone, dynamic range performance, tri and quad-wavelength optics and is fully configurable. In other words, it's the only piece of equipment you'll need for all your basic fiber optic testing ---whether for installation, maintenance or fault location.

The CMA4000 makes your job faster and easier withdozens of unique features:

• One button to test and save
• Automatic evaluation of the test fiber for connection quality and traffic
• Multi-tasking software simultaneously tests and analyzes trace data to display results in seconds
• A panel of dedicated keys for easy access to functions you use most, as well as, a convenient onboard keyboard for entering file names
• Automated software prompts the user for required information about the cable under test and keeps track of the fibers as they are tested

Easy documentation makes it simpler for you.

The programmable autosave lets you save test results on a hard drive or floppy in a format that makes sense for your network. These features virtually eliminate typing mistakes while saving time in the field. When used in conjunction with our GN NetWorks Software, the CMA4000 can perform a variety of trace manipulations, such as trace overlay, graphing, batchprinting and bi-directional averaging reports.

Incredible dynamicrange and short deadzones.

The CMA4000 offers a test range of 21 to 46 dB, the highest dynamic range in the world. That means you can test longer lengths of fiber with greater resolution and less averaging time. Plus, with deadzones as short as 2.5 m, you can be sure you're getting complete and accurate data for your entire length of cable.

The best value foryour money.

The CMA4000 is the one piece of equipment that can meet virtually all your basic fiber optic testing needs. If you choose to incorporate a standard power meter, optical return loss test set, light source and visual fault locator, it's the only piece of equipment you'll need. You can also customize your unit with optional languages, power cords, connectors, keyboard layouts, and date and time formats. The built-in keyboard lets you enter important text data, and the large 8.4" display with optional VGA color and flexible configuration makes the screen easy to read under any testing condition. Plus, the environmentally sealed modules and buttons --- along with its rugged casework -protect the CMA4000 from dust, rain and impact.
