Product Details

The Industry Leader in Optical Performance
High performance networks demand even higher performance test and measurement equipment -- and there's no better solution than NetTest's award winning test and measurement solutions. Our newest offering, the CMA4000i, continues the NetTest tradition of being the worldwide leader in optical test and measurement.

With 50 dB of dynamic range and deadzones as small as 3.0 m, the CMA4000i is ideal for testing long haul backbone networks, metro networks or Passive Optical Networks (PONs). For complete system characterization, the CMA4000i can be easily equipped with a light source and power meter for complete end-to-end loss testing. In addition, the Visual Fault Locator (VFL) option for the CMA4000i enables you to locate breaks within the OTDR's deadzone or identify specific optical fibers within a cable. The System offers a variety of operating modes for varying OTDR applications.

DWDM System Qualification
For commissioning or maintaining networks that employ DWDM technology, the model 4792 OSA module for the CMA4000i is the ideal instrument. It allows the testing of DWDM networks deployed both today and in the future. Operating from 1520-1620 nm (C- and L-band), the model 4792 OSA module for the CMA4000i Optical Test System can automatically identify over 400 DWDM channels spaced less than 12.5 GHz apart -- perfect for testing high capacity DWDM systems.

Characterizing complex DWDM systems is simple with the CMA4000i. One-button operation ensures that even the novice user is capable of characterizing a complex DWDM system for channel center wavelength, power, and OSNR. Simply power on the unit with the OSA module installed and one of the following views will be displayed: Table View, Drift View, or Graph View.

Features

• Highest Dynamic Range in the industry-50dB
• OTDR, Loss Test Set and VFL in a single module
• Optical Spectrum Analyzer module with 10 GHz
• channel resolution
• One-button testing

Operating Modes

Fault Locate Mode
With a one-button auto test option, the CMA4000i brings ease-of-use to a new level. Simply attach the fiber to the instrument, press Fault Locate and your entire fiber optic cable is completely characterized for attenuation, splice loss,and reflectance. For those users who require more flexibility in their measurement, the CMA4000i offers the following modes to bring OTDR testing to a higher level.

Construct OTDR Mode
Construct Mode simplifies and automates the tests and documentation most frequently performed during fiber installation. Construct Mode is designed for testing multiple fibers and is ideal for cable installation and commissioning.

Construct Mode eliminates the time consuming setups common to the repetitive practices of testing, storing, analyzing, and documenting high fiber count cables From the setup screen, the operator can quickly select one or all wavelengths to test, and determine the file naming structure, and specific fiber count for a given cable. Once set up, the OTDR acts as a Òtask masterÓ to perform the following functions:

• Select the wavelengths
• Test the fiber at all selected wavelengths
• Analyze the trace data
• Store the trace and analysis data to either floppy or hard drive
• Alert the technician to move to the next fiber to be tested and increment the filename to the next sequential number

Expert OTDR Mode
Expert OTDR allows the user to perform traditional OTDR functions with dedicated hard keys tied to frequently used OTDR parameters such as pulse width, range/resolution, and wavelength. This mode provides unsurpassed user flexibility for optimization of OTDR parameters without stopping the test in progress. Key features of the Expert mode include:

• Real-time Testing
• Splice Optimization
• Loss Mode Setup
• Dual Wavelength Testing
• Trace Compare Mode
• Trace Shift Capability

Views

Table View
Table view is ideal for quickly characterizing a DWDM system's essential features and performance. The number of channels, channel spacing, and relative power between channels is immediately visible. The table also shows each channel's wavelength/frequency, power, optical signal-to-noise ratio (OSNR), delta wavelength, and delta power.

Graph View
Graph view displays full spectrum data and allows full manipulation of the waveform. Since this view displays the entire spectrum at all times, the user can zoom in while still maintaining a full spectrum view. In addition, it allows acquired and recalled data to be displayed together; this is especially useful for comparing spectra, analyzing channel power flatness, and viewing channel spacing.

Drift View
Drift view is used in conjunction with the drift acquisition mode and is ideal for evaluating long-term power and wavelength stability of DWDM channels. This view displays channel number, reference wavelength, reference channel width, current wavelength, current power, minimum/maximum detected wavelength and detected power. It can also be used to compare the received channel frequencies to the ITU standard DWDM grid or a user-defined template - making field procedures simpler than ever.

Detailed Product Description

NetTest's OVS-6000 offers premium fiber optic talk sets for communication over single-mode fiber in a variety of field environments. Three models are available for medium-range or long-range communications that span over 200 km distances. All sets offer noise-canceling and "hands-free" headsets to simplify communication during splicing, testing or maintenance applications. Units can also be used as a 2 kHz light source to conduct point-to-point loss readings or fiber identification.
