| COMMUNICATIONS TEST & MEASUREMENT Swept Wavelength System SWS2000 Series Key Features * Scalable architecture - add more stations any time * 0.002 nm absolute wavelength accuracy * Up to 128 detector channels available per station * Remote source laser can be shared by up to 8 workstations * High speed scanning (user controllable) up to 40 nm/s * Flexible easy-to-use software * Customized applications through dynamic link libraries (DLLs) * 24/7 service and support Applications * Optical component and module characterization in both R&D and manufacturing environments - ROADMs, Wavelength Switches, Wavelength Blockers - Circuit Packs - Dense wavelength division multiplexing (DWDM) - Tunable Filters, Couplers, Splitters, Switches, Attenuators, Fiber Bragg Gratings (FBGs), Interleavers, Dichroic Filters - Micro-Electro-Mechanical Systems (MEMS) and Waveguide Devices - Complies with IEC 61300-3-29, IEC 61300-3-12 The Swept Wavelength System SWS2000 series remains the industry standard solution for measuring insertion loss (IL), polarization dependent loss (PDL), return loss (RL) and directivity with high wavelength resolution in both research and development (R&D) and production environments. Currently used at more than 80 customer sites, with over 8500 detector channels deployed, the SWS test platform validates optical performance for the latest in optical components and modules including: ROADMs, Wavelength Switches, Tunable Filters and Circuit Packs. The SWS system consists of a tunable laser source, a source optics module (SOM), a control module, a receiver chassis, one or more detector modules and application software. With a 0.002 nm absolute wavelength accuracy over the entire 1520 to 1630 nm range, a high sweep speed of 40 nm/s, and a deep dynamic range of > 70 dB, the SWS2000 provides excellent performance combined with a low cost of ownership; the distributed architecture supports up to eight separate, individually controlled measurement stations per source laser. Often purchased initially as an R&D tool, this scalability in the number of measurement stations provides customers the flexibility to transition the equipment from R&D to production. Upgrade packages from legacy SWS systems to the SWS2000 platform are available to ensure that existing SWS users receive the maximum benefit from their existing capital infrastructure. Safety Information * Complies to CE requirements plus UL3101.1 and CAN/CSA - C22.2 No. 1010.1. The laser source in the Source Optics Module (SWS20010) is a class 1. The Tunable Laser Source (SWS17101) is a class 3B laser. Both are classified per IEC standard 60825-1(2002) and comply with 21CFR1040.10 except deviations per Laser Notice No. 50, July 2001. WEBSITE: www.jdsu.com SWEPT WAVELENGTH SYSTEM (SWS2000) 2 Continued SWS directly measures IL, PDL and average loss as a function of wavelength. RL is measured with the optional RL modules (SWS20005). Using the raw IL and PDL data, the application software provides a comprehensive set of analysis tools that calculate: * Loss at peak * Center wavelength, from x dB threshold * Loss at center wavelength * Bandwidth at x dB threshold * Crosstalk, left/right and cummulative * Flatness These parameters are calculated relative to the measured peak, ITU grid or userdefined grid. The SWS is delivered with a set of DLLs that can be used to develop software to suit custom testing requirements. The DLLs function through the SWS receiver hardware, allowing access to all SWS functionality. Using the supplied DLLs, applications may be developed in Visual BasicTM, C, C++, or LabView environments. With a 4-State polarization controller located within the SOM, PDL and average loss are measured quickly as a function of wavelength. Four polarization states at 0, 90, - 45 and circular polarization are measured, and the Mueller matrix analysis is used to accurately determine PDL at all wavelengths scanned. When the very highest accuracy PDL measurements are required, a special version of the detector module should be used. The SWS15107-A contains specially selected and tuned components to allow PDL measurement to an accuracy of better than 0.01 dB. This module is supplied with a fixed FC/APC connector. All specifications listed are met simultaneously. No change in wavelength accuracy ( 2 pm) or scan speed (20 nm/s) is required to obtain a 70 dB dynamic range.

Safety Information * Complies to CE requirements plus UL3101.1 and CAN/CSA-C22.2 No. 1010.1. The laser source in the Source Optics Module is a class 1 laser. The Tunable Laser Source (SWS-17101) is a class 3B laser. Both are classified per IEC standard 60825-1 (2002) and comply with FDA standard 21CFR 1040.10 except deviations per Laser Notice No. 50, July 2001. With the simple addition of an RF modulator within the SOM and an OMNI receiver, an existing Swept Wavelength System SWS2000 system can be used to measure group delay (GD) and differential group delay (DGD). Existing test stations can still be used. SWS-OMNI adds to the SWS family of test systems and provides leading-edge performance for fast all-parameter testing for efficient engineering, research and development (R&D) and production testing operations. SWS-OMNI rapidly and accurately measures insertion loss (IL), polarization dependent loss (PDL), GD and DGD characteristics of a wide range of passive optical components and optical fiber using a dual channel receiver for higher-throughput and lower-cost testing. The modular architecture of the SWS-OMNI enables a user to add the SWSOMNI receiver to an existing SWS transmitter to provide a stand-alone all parameter test station without the added expenditure of another tunable laser and wavelength meter. These additional test stations are purchased at a relatively low incremental cost providing best multi-station capital expenditure economics in the industry. From phase and IL measurements, SWS-OMNI software calculates CD, PDL, GD and DGD as a function of wavelength or frequency. Displayed data may be further analyzed on-screen using markers, or setup to automatically analyze the data in the parameter ranges defined. This data can be exported for further analysis. The software also has dynamic link libraries (DLLs) that can be used to easily develop custom software in LabVIEW, Visual Basic or C+ a feature that is especially useful in a production environment. SWEPT WAVELENGTH SYSTEM (SWS-OMNI EXPANSION SERIES) 7 Continued SWS-OMNI Virtual Modulation Frequency Feature (VMFF) To improve the group delay noise and resolution, conventional modulation phase measurement techniques often employ an adjustable modulation frequency, which needs to be set before measurements are made. In contrast, the SWS-OMNI system uses the proprietary VMFF. All swept group delay measurements are made at a fixed modulation frequency (192 MHz) optimized for the 3 pm wavelength sampling step of the SWS. The data is then post-processed to achieve higher effective modulation.
