Avanex Introduces Tunable Platform for In-Line Dispersion Compensation Management.FREMONT, Calif. -- Avanex Corporation (Nasdaq:AVNX) a pioneer of intelligent photonic solutions that enable next-generation optical networks, today introduced its in-line Tunable Dispersion Compensator A device that removes pulse distortion in an optical fiber network. It is usually placed near the optical amplifier spaced some 25 to 50 miles apart. See dispersion.

The PowerShaper(TM) 3200 platform is the industry's only broadband TDC solution compatible with both 10Gb/s and 40Gb/s transmission speeds. This product platform provides remotely tunable dispersion and 100 percent slope compensation for all C-band channels simultaneously with signal pass-band fidelity. The emergence of reconfigurable networks and the migration to 10Gb/s and 40Gb/s transmission speeds requires signal fidelity to be maintained over a broad range of system configurations. Additionally, as bandwidth usage increases, remote network reconfiguration is increasingly critical and is needed to lower installation and maintenance costs. Tunable dispersion compensation management is critical to maintain signal fidelity and minimize transmission penalty. The PowerShaper platform is a compact and simple to use module that can be seamlessly integrated into the mid-stage of an Erbium erbium (ûr`bēəm) [from Ytterby, a town in Sweden], metallic chemical element; symbol Er; at. no. 68; at. wt. 167.26; m.p. 1,529°C;; b.p. 2,863°C;; sp. gr. 9.05 at 25°C;; valence +3. Doped Fiber Amplifier (EDFA (Erbium-Doped Fiber Amplifier) A device that boosts the signal in an optical fiber. Introduced in the late 1980s, the EDFA was the first successful optical amplifier. ) or DWDM (Dense WDM) The term given to wavelength division multiplexing (WDM) when significantly more channels were being added. Since WDM is increasingly more "dense" all the time, both terms are used synonymously. See WDM. DWDM - wavelength division multiplexing demultiplexer. This both enables flexibility required by next-generation networks and reduces the overall cost of dispersion compensation management throughout the network. The intelligent digital control system employed in the Avanex TDC platform overcomes complex control, stability and fidelity challenges to achieve an unprecedented <5ps of peak to peak Group Delay Ripple. The module can be tuned remotely or by an integrated closed loop control system to optimize and maintain network performance without network operator intervention. The module can also be used in "set and forget" mode as a substitute for fixed dispersion compensators. The PowerShaper is compact by design (100x130x15mm) and employs proprietary etalon In optical networking, an etalon is a passive filter that uses a Fabry-Perot cavity.

It is measured as the spacing between center frequencies (or wavelengths) of adjacent channels. See guard band. , and precise control of dispersion to <20ps/nm. PowerShaper 3200 product platform will be presented at Avanex booth 2141 at the Optical Fiber Conference and Exhibition (OFC/NFOEC) held at the Anaheim Convention Center Anaheim Convention Center is a major convention center in Anaheim, California. It is located across from the Disneyland Resort on Katella Avenue. Much of the Anaheim Convention Center has been renovated in recent years with state-of-the-art facilities. in Anaheim, Calif. between March 26-29.
