Acterna Introduces New High-Performance Additions to Family of DWDM Spectrum Analyzers for the Acterna ONT Platform at China Elecomm 2004

<p>- Functionality and Performance of Two Separate Measurement Instruments Combined in Compact, Modular Field Solution Without Performance Compromise</p>
<p>Shanghai, China and Hong Kong: June 23, 2004 -- Acterna today introduced the Acterna OSA-300/301 high-precision optical spectrum analyzers for customers with testing needs for ultra dense wavelength division multiplexing (U-DWDM) applications, the next generation WDM technology. The OSA-300/301 is the first field test module which effectively combines a lab performance optical spectrum analyzer (OSA) with a resolution bandwidth of &lt;50pm and a unique channel isolation functionality for extracting specific signals up to line rates of 10.7 Gbps.</p>
<p>For maintenance and troubleshooting of high performance DWDM networks, test instruments like optical spectrum analyzers and optical channel selectors are essential for measuring optical parameters and for extracting single optical channels out of a DWDM signal for further analysis. By combining a new high-performance OSA and the well-known tunable channel-isolation function from Acterna's OSA-161/201 into one test module for the Acterna Optical Network Tester (ONT-50) platform, network operators and manufacturers gain several benefits. Two instruments combined in a single module saves money and space. Customers achieve time efficiencies because the OSA-300/301 enables optical performance analysis of the spectrum and channel isolation for further testing.</p>
<p>"Manufacturers and carriers continue to execute on their vision of converged networks and technologies like DWDM, quickly bringing what have previously been considered futuristic technologies to the present," said Enzo di Luigi, general manager for Acterna's fiber optic unit. "By creating a two-in-one product without compromising performance, Acterna can now provide them with an unmatched solution for accelerating installation, commissioning and troubleshooting using our ONT-platform."</p>
<p>The Acterna OSA-300/301 modules are the latest additions to the Acterna family of spectrum analyzers. While all Acterna OSA optical spectrum analyzers offer high-performance optical measurements over the full wavelength range between 1250nm and 1650nm at high test speed, the OSA-300/301 modules deliver new advantages. They offer lab-type optical performance with a 10dB improvement in optical rejection ratio (ORR) compared to its predecessors, enabling accurate measurements in DWDM networks with high-channel counts and tight-channel spacing.</p>
<p>The channel-isolation function, with a tuning range covering the entire spectrum from 1250nm up to 1650nm, simplifies test and troubleshooting in dense wavelength division multiplexing networks (DWDM) as well as in coarse wavelength division multiplexing networks (CWDM) used in metro applications. This function can be used to further qualify optical signals using BER testers or Q-factor meters.
All OSA modules provide industry-leading wavelength accuracy (10pm) that is guaranteed over their lifetime. This is achieved by an internal on-line wavelength calibrator which is based on a physical constant reference, guaranteeing the highest wavelength accuracy over instrument lifetime without recalibration.</p>
<p>Additional features of the Acterna OSA-300/301 include: graphical and tabular display formats that can be selected for use during installation and maintenance of multi-channel WDM systems; the FOX auto mode (Fiber Optic eXpert), which provides automatic PASS/FAIL evaluation based on customer predetermined limits at the push of a button; built-in test functions like EDFA and laser-source test applications, which facilitate network component verification; and the availability of long-term optical performance monitoring software.</p>
