Multiplay test products
The N2X Multiservices Test Solution combines line-rate, hardware-based performance statistics for video, voice, and data services on the same test port. The N2X provides scalable hardware-based, triple-play traffic generation and analysis based on user-defined subscriber profiles. Each test port displays video media quality and IPTV channel-zapping metrics along with voice Mean Opinion Score and data forwarding performance measurements. This capability allows network equipment manufacturers and service providers to identify how the number and behavior of subscribers and traffic mix affects overall quality of experience, and to validate the triple-play readiness of network infrastructure equipment prior to deployment. The J6900A Triple Play Analyzer is an in-service monitoring, analysis, and troubleshooting tool for voice, data, and video applications. Designed as a component of the Triple Play Analyzer platform, the analyzer enables service providers and network equipment manufacturers to accelerate deployments of Microsoft Mediaroom-based IPTV services.

The P-Series OptiCop 10G Converger provides non-intrusive monitoring access for Packet over SONET/SDH (PoS) networks. The converger can translate 10G PoS traffic into Ethernet traffic to enable service providers to leverage their existing GbE and 10-GbE tool investments, and enable test and monitoring access across any network topology. Its out-of-band broadband monitoring access lets service providers optimize tool port usage without degrading the service or distorting the results. Using the company's Hybrid Inspection Technology (HIT), OptiCop 10G Converger empowers service providers with packet inspection and filtering capabilities that can separate the traffic at the service level and distribute it to the appropriate network monitoring tools from a single network tap or span port. The tools can monitor SONET/SDH PoS circuits ranging from OC-3/STM-1 through OC-192/STM-64 and monitor multiple circuits in either half- or full-duplex scenarios.

The FiberMASTER portable five-wavelength fiber testing kit measures critical power and optical signal loss on standard wavelength windows, as well as on FTTx applications. At the heart of the FiberMASTER is a five-wavelength power meter with calibration function that stores reference power levels for quick decibel-loss measurements, therefore eliminating the requirement to manually calculate loss. When joined with the included 850-nm "docking" light source, the power meter measures fiber-optic power in milliwatts (mW) and decibel-milliwatts (dBm), as well as fiber signal loss at 850-, 1300-, 1310-, 1490-, and 1550-nm wavelengths. The power meter with an 850-nm source is priced at $749, while 850- and 1300-nm sources are priced at $95. The unit comes with universal and FC adapters for the meter interface, and free SC, ST, and FC adapters for the light source.
