JDSU dynamic gain equalizer products compensate for uneven gain profiles inherent in optical amplifiers. This allows the cascade of multiple amplifiers, thereby helping to eliminate expensive regeneration equipment and reducing overall optical system costs. The DGE simultaneously provides a smooth optical attenuation profile of wavelengths (low resolution) and compensates for local spectral features (high-resolution). The JDSU variable slope attenuator (VSA) equalizes uneven gain profiles with an attenuation slope that is tuned using a precise stepper motor. The DGE and VSA can be adjusted remotely and dynamically and are available for either C or L band. JDSU's Agile Optical Switch family provides the broadest portfolio of ROADM solutions designed to match the requirements of major market segments. They are the building blocks of Agile Optical Networks and provide the flexibility to remotely reconfigure any or all wavelengths, thereby reducing time-to-service, simplifying the network and streamlining planning and management. This results in significant Opex and Capex reductions and faster time to revenue. In addition, they enable the cost effective creation and deployment of more complex network architectures. The JDSU dynamic gain equalizer (DGE) eliminates expensive regeneration equipment and reduces overall optical system costs for deployments of 10 Gb/s ultra-long haul and 40 Gb/s long haul optical networks. The DGE simultaneously provides a smooth optical attenuation profile of wavelengths (low resolution) and compensates for local spectral features (highresolution). This enables the cascade of up to 50 optical amplifiers and translates into a system reach extension of up to 5000 km. The DGE, as well as the Wavelength Blocker series of modules, provides state of the art performance for dynamic optical networks. These advanced modules use free-space optics, replacing conventional components thereby reducing costs and complexity. * Polarization dependent loss (PDL) <0.3 dB * Polarization mode dispersion (PMD) <0.3 ps * Enable transport of managed information in optical systems at lower cost * Empower bandwidth on-demand and network agility * Standard interface with Wavelength Blocker modules * Corrects imperfect gain flatness in a chain of cascaded optical amplifiers over wavelength operating range * 10 Gb/s ultra-long haul and 40 Gb/s long haul dense wavelength division multiplexing DWDM) systems * Optics block and modules passed Telcordia GR-1221, GR-1209 and GR-1312 http://products.jdsu.com/assets/public/pdf/dge_ds_cms_ae_020806.pdf (please look at our rules and privacy policy) |
