Alcatel-Lucent adopts testers for IPTV
Alcatel-Lucent has chosen Agilent as a formal test and measurement partner for its IPTV ecosystem.
Alcatel-Lucent has chosen Agilent as a formal test and measurement (T and M) partner for its IPTV ecosystem. The partnership will enable collaboration to ensure that new IP-based video deployments meet end-to-end service-quality expectations. Agilent test solutions provide a holistic approach to measuring and monitoring video service quality from R and D and lab-based performance validation, through to service assurance and network troubleshooting.
Realising the critical role that T and M solutions play in the effective delivery of IP-based video services, Alcatel-Lucent has proactively established formal relationships with best-in-class vendors in the IPTV T and M segment.
Service providers and network equipment manufacturers face the challenge of converging new IP-based video services, such as IPTV and video on demand (VOD), with existing voice and data services to residential customers over a single access point.
Ensuring network integrity, quality of service (QoS) and subscriber quality of experience (QoE) is critical to the success of video service deployments.
Agilent offers a portfolio of solutions for testing video service quality, including research and development through to network installation and ongoing monitoring.
Agilent equipment provides stress testing and service validation prior to and during the installation process, which significantly reduces post-deployment performance issues and helps prepare new service offerings for production networks.
Agilent's monitoring tools provide real-time video-quality analysis and troubleshooting for live video service deployments, which is critical given the complexity and ever-changing conditions within next-generation triple play networks.
These test solutions help network equipment manufacturers and service providers reduce time to market, lower development costs and minimise risks for new IP-based service offerings.
Alcatel-Lucent's IPTV ecosystem includes the following Agilent equipment.
The Agilent N2X multiservices test solution provides predeployment verification of IPTV service quality under highly scaled and dynamic triple play network conditions.
The N2X emulates thousands of dynamic IPTV subscribers and generates triple play video, voice over IP and data (high-speed Internet) traffic to place significant stress on IPTV network equipment.
N2X delivers real-time MDI metrics, protocol decodes and post-capture replay for IPTV traffic.
The Agilent J6900A is triple play analyser, which provides complete analysis and troubleshooting in a single platform for installation, monitoring and troubleshooting of voice, data and video services.
The analyser provides accurate measurements of VoIP, IPTV and VoD Quality of Experience as well as real-time channel-zapping analysis.
The Agilent FrameScope Pro handheld instrument allows technicians to measure point-to-point network performance and to correlate triple play transport quality and QoS with end-user QoE.
Its network test toolbox provides insights into network impairments and helps locate failures and bottlenecks.
'Agilent equips network equipment manufacturers and service providers with the tools they need to measure video service quality at the most granular level', said Rod Unverrich, Business Manager of Agilent's Data Network Operation.
'Our video test solutions address all stages of the test cycle to improve both the time to market and performance of new video service deployments'.

Options expand range of digital comms analyser
Agilent Technologies has introduced industry-first phase noise application software and options for the DCA-J digital communications analyser.
Agilent Technologies has introduced industry-first phase noise application software and options for the digital communications analyser (DCA-J). The software allows phase noise/spectral jitter analysis of clock and data signals over a wide dynamic range from 50Mbit/s to 13.5Gbit/s. A new optical/electrical module provides optical transmitter test and 40Gbit/s optical compliance test; an advanced amplitude analysis option offers new methods for optical modulation amplitude and relative intensity noise.
These enhancements prove the DCA-J's leading-edge performance and capabilities as an affordable, comprehensive, easy-to-use sampling scope for optical and electrical applications.
The multirate wide loop bandwidth clock recovery module allows precision waveform measurements with a variety of signals, including spread spectrum clocked.
This is the industry's first phase noise application software, which allows phase noise/spectral jitter analysis of clock and data signals ranging from 50Mbit/s to 13.5Gbit/s.
Many serial bus architectures employ spread spectrum clocking for better signal integrity, known as electromagnetic interference (EMI) management.
Hardware clock recovery elements of sampling oscilloscopes have not been able to follow the large amounts of jitter produced with spread spectrum clocks, making meaningful measurements virtually impossible.
This has been overcome with the Agilent 83496B.
The 83496B and phase noise application software reveal root causes of jitter through frequency domain analysis - an effective and easy method for detecting jitter sources.
Also, this solution can perform the analysis on both clock and data signals, so the root causes of data jitter can be related to system clocks.
'This tool allows our customers to see the root causes of jitter, whereas other measurement tools are limited in dynamic range or in the types of signals they can observe', said Sigi Gross, Vice President and General Manager of Agilent's Digital Verifications Solutions Division.
In addition, the DCA-J offers three new functions for optical applications.
The 86116C can be used as a 65GHz oscilloscope channel or switched to a reference receiver for 40Gbit/s optical transmitter eye-mask test.
Carefully controlled frequency response allows operation as a reference receiver and provides consistent and accurate eye mask tests.
It can be configured at standard or FEC rates for OC-768, STM-256 and related specifications.
Just as the DCA-J revolutionised jitter analysis, DCA-J option 300 provides the same industry-accepted analysis now translated into the amplitude domain.
This enables capabilities such as relative intensity noise (RIN) measurement, a common specification for optical transmitters.
Historically, RIN measurements have required expensive or complicated test equipment.
Now, with this software, eye-mask tests and RIN measurements can be performed quickly and accurately using the same equipment and at the same time.
Option 300 also allows separation of interference parameters to extremely low probabilities, providing an accurate measurement of Q-factor, commonly used to estimate bit error ratio.
Agilent's new Rev 7.0 firmware for the 86100C DCA-J enhances the system through a novel approach to the measurement of optical modulation amplitude (OMA), a common specification for optical transmitters.
The general OMA test requires special data patterns.
Agilent's 86100C provides the correct OMA result for these patterns, and has the added flexibility to provide an accurate OMA result for virtually any data pattern.
This flexibility eliminates the need to reconfigure the stimulus, saving measurement time for a complete characterisation of the transceiver.
All products will be available from 1st February 2007.
The Agilent 83496B multirate wide bandwidth clock recovery module will start at US $18,500.
The 86116C optical/electrical module will start at $64,089.
The 86100C Option 300 amplitude interference/RIN/Q-factor software will cost $2800.
The Agilent 86100C Infiniium DCA-J firmware revision 7.0 will be available at no charge via the web.

Exfo Electro-Optical Engineering has evolved its optical transport network (OTN) test solution with the availability of ODU1 to ODU2 multiplexing test capabilities on its Transport Blazer test modules. As defined in the ITU-T G.709 (Optical Transport Network) standard, the Optical Channel Data Unit (ODU) multiplex/demultiplex scheme allows four ODU1 signals within one ODU2 signal structure. This scheme provides a cost-efficient means of transporting 2.5G dense-wavelength division multiplexed (DWDM) services onto 10.7G DWDM wavelengths.
Exfo's enhanced OTN test solution supports OTU1 (2.7Gbit/s) and OTU2 (10.7Gbit/s) test rates, as well as ODU1 to ODU2 multiplex/demultiplex schemes.
In addition, it covers forward error correction (FEC) generation/analysis, all OTN layer-alarm generation/monitoring, and trace-message generation/analysis.
This combined feature-set is offered as a Transport Blazer test module for the FTB-200 compact platform to produce the most portable and lightweight OTN solution in the industry.
It can also be hosted in the FTB-400 universal test system and IQS-500 intelligent test system for field deployment, maintenance, troubleshooting and lab applications.
'Exfo's Transport Blazer test solution continues to evolve as customer deployments and requirements become more well-defined, especially with regard to optimising DWDM networks', said Etienne Gagnon, Exfo's Vice-President of Protocol-Layer Product Management.
'OTN deployments are growing and increasingly becoming more important as reconfigurable optical add-drop multiplexers (ROADMs) gain acceptance'.
'As a result, the need for advanced OTN test capabilities is becoming more apparent and Exfo is once again at the forefront of the innovation curve with a comprehensive technology offering in a compact format'.
