From physical layer, data link layer, network layer to transport layer, CMA5000 provides a real multi-layer network testing solution.

  CMA5000 is the first high-performance and scalable test and measurement solution in the industry, which can meet the demanding requirements of communication professionals, accelerate the opening of new services and reduce the overall measurement cost.

   CMA5000′ s open structure design, powerful functions and modular platform can provide the highest performance measurement application, which can help users analyze and open the network faster than competitors and start making profits earlier. In addition, the configuration flexibility and expansibility of CMA5000 enable it to be improved with the change of users’ test requirements and the constant change of telecom infrastructure technical requirements.

  I. Analysis of Physical Layer Characteristics

CMA5000 continues NetTest’s long-term leading position in the field of optical fiber and network characteristic analysis. CMA5000 OTDR application provides a dynamic range of over 50 dB, and can obtain the required OTDR test information on any link in a few seconds.

  Providing the best OTDR performance is only a good beginning. In the process of comprehensive analysis of physical layer media characteristics, the function and scalability of CMA5000 platform are particularly prominent. Combined with the best OTDR in the industry, CMA5000 can provide all the test applications needed for perfect physical medium characteristic analysis, including:

chromatic dispersion

Polarization mode dispersion

Visible fault locator

photographone

Optical return loss

Visual detection probe (for connector inspection)

Loss tester

Second, the DWDM network equipment installation

  With the beginning of network installation, the final delivery deadline is approaching day by day, and time is of the essence. During the equipment installation, CMA5000 can help you complete the task correctly once, which speeds up the deployment of the network. With the intuitive display of information including channel wavelength (or frequency) and power, OSNR and system gain slope, the application of spectral analysis (OSA) and optical channel analysis (OCA) provides accurate and efficient network channel management, power balance and adjustment.

  In addition to the industry-leading OSA and OCA performance, CMA5000 also provides a visual inspection probe (VIP) to verify the connector quality, and the optical power meter is used to measure the power of a single channel or the overall system power. When used with high power amplifiers and pump lasers, safety is the key. VIP provides a safe and reliable method for inspecting, evaluating and recording the end face condition of connectors, thus avoiding potential dangerous situations.

  Whether testing transmitter, amplifier, receiver or other optical devices, CMA5000 OSA, OCA, visual detection probe and optical power meter all provide the required performance for the rapid installation of network equipment.

Third, the network is opened

  Today’s competitive environment requires the network to provide extremely high performance and reliability, ensuring that the failure time is minimized. CMA5000 is once again your best choice for characteristic analysis and archiving under such strict performance level requirements. The application of optical transmission analysis (OTA) provides efficient and reliable testing for many parameters, including alarm and error code analysis, APS with 125 μs resolution, round-trip delay measurement with 100 ns resolution, and network availability and performance evaluation. OTA application can analyze the characteristics of PDH/T-carriers to SONET/SDH with a speed of up to 10 GB/s. In addition, OTA’s innovative fault scanning function can automatically detect problems, so as to quickly identify and correct network damage and ensure that the network meets your and your customers’ expectations.

Fourth, business deployment

  When the network construction is about to be completed, customers will be eager to deploy new services. At this time, time is of the essence. CMA5000 Gigabit Ethernet application can help you meet the challenge and ensure that key parameters including throughput, delay, frame rate, lost frames, etc. (see RFC 2544 for details) are met, thus accelerating business deployment. In addition, the measurement of error code at the frame level and the comprehensive IP statistics function enable CMA5000 to provide key layer 2 QoS information. Gigabit Ethernet test application provides the required performance for the installation, maintenance and fault location of Ethernet network based on 10/100/1000 Mbps with its unparalleled high efficiency and ease of use.

  The flexible and extensible design of CMA5000 integrated test platform integrates the best functions of each test application, which accelerates business deployment, reduces measurement costs and optimizes bandwidth.
