Characterizing and Verifying Compliance of 100 Gb Ethernet Components and Systems - Application Brief

09/17/2014

Ethernet data bandwidth expansion from 10 Gb/s to 100G (and 1 Tb/s in the future) is a direct result in the rapid growth of capacity in modern data centers. The recent release of a series of Standards supporting 100Gb Ethernet and 32G Fibre Channel enables component and system designers to implement next generation designs utilizing serial links at these speeds. Download the application note to learn new measurement techniques needed to characterize designs and validate compliance to Standards using 25/28 Gb/s line data rates.

Delivering Exceptional VoLTE Service Quality

08/08/2014

Voice is, and will continue to be, a core mobile service. VoLTE is the voice service of the future, embracing better quality, faster connection times, and the integration of rich communication services. VoLTE delivers many operator advantages as well as user advantages over today’s voice services. However, as we have seen, VoLTE is not without its challenges. To be successful in delivering a good VoLTE customer experience, operators will need to be able to test, troubleshoot, manage, and optimize both the network and services to ensure they meet user expectations.

Adoption of Cloud Computing Hinges on Application Performance

05/07/2014

Smart network application platforms provide a cloud-based approach to embed data-capture technology throughout the network, delivering in-line intelligence to any monitoring, management, or business application. If an operator can decouple data collection and filtering from management, aggregation, and analysis, and then distribute throughout a cloud-based network, the operator can dramatically reduce the cost, footprint, and complexity of capturing rich intelligence about the network, the content, and customers’ experience. This provides unprecedented access to intelligence across the network and especially to the network edge where 80 percent of customer issues occur, making networks more efficient and cost effective. Most importantly, cloud-based networks preserve the value of existing infrastructure and personnel while simultaneously enabling these resources to perform better and more efficiently.

Jitter Analysis on Oscilloscopes and BERTs

02/11/2014

Jitter can be analyzed on various test equipment: oscilloscopes, spectrum analyzers, phase noise analyzers, even vector network analyzers can play a key role, but the bit error rate tester (BERT) is the only equipment that can measure the single most important jitter quantity.

Maintenance Testing with an Out-of-Band OTDR

02/11/2014

Since its inception, the optical time domain reflectometer (OTDR) has become the standard for measuring optical fiber distances and loss characteristics. During installation or certification, optical fibers are typically tested with an OTDR at the wavelengths that could or will be transmitted over them. This confirms that the fibers and associated components are capable of efficiently passing these wavelengths and all characteristics are within specification. Since the fiber is not in service or “dark”, there are no interfering transmissions present. On the other hand, maintenance and troubleshooting need to be performed after the fiber is placed into service. For traditional networks, this would ideally be done “after hours” in the maintenance window, when service can be shifted
to another spare fiber. For some networks, such as PON-based FTTx, it may not be possible to wait or shift the traffic, so in-service or “live” fiber testing may need to be performed. Due to this need, the International Telecommunications Union (ITU) has produced recommendations for out-of-band and maintenance testing of optical networks:

  • ITU-T Recommendation L.66: Optical fibre cable maintenance criteria for in-service fibre testing in access networks
  • ITU-T Recommendation L.41: Maintenance wavelength on fibres carrying signals

Wireless Ethernet Backhaul

02/11/2014

The wireless backhaul market is witnessing significant growth resulting from new protocol data applications. To support the increase in wireless backhaul growth, fiber optic backhauls are being installed throughout the network and up the tower to the antennas. In addition to fiber optic, Ethernet packet transport is becoming increasingly popular as the protocol data transport through the wireless backhaul due to its flexible capability and logical topology meeting the needs of current and future protocol data requirements. As a leader in optical transport measurement tools, Anritsu is committed to provide current and next Generation measurement tools to assist our customers with accurate and efficient network performance.
