MARCH 28, 2007 -- Capella (search for Capella), a provider of wavelength-selective switches (WSSs) for use in reconfigurable optical add/drop multiplexer (ROADM) and optical crossconnect (OXC) applications, has announced the qualification of its WavePath 4500 with integrated optical channel monitor (OCM) in accordance with Telcordia and other worldwide standards.
Elizabeth Perry, vice president of engineering, notes that "Capella's WavePath 4500 modules have gone through a battery of environmental, mechanical and operational stress tests to quantify and characterize lifetime reliability. Tests performed and passed followed guidelines set forth in GR-468, GR-1312, GR-63, GR-1073, FOTP-11, ETS 300, and other appropriate or required standards."
Shoa-Kai Liu, senior advisor at Rustic Canyon Partners and former director of network technology development at MCI, adds, "Completing qualification successfully enables Capella's customers to move forward with planned network deployments with the assurance that these switching fabrics provide the needed robustness and carrier-grade performance to manage and protect next-generation IP over optical networks being planned and deployed worldwide."
The MEMS-based switch module with integrated OCM offers high-performance 9×1 or 1×9 WSS functionality featuring wide passbands and low insertion loss, maximizing cascadability of transparent nodes and minimizing amplification costs. The integrated OCM provides power monitoring, center wavelength monitoring, signal-to-noise-ratio variance, and the unique diagnostic ability to verify all connections through the subsystem—Capella's patented Wavelength Connectivity Confirmation. The closed-loop control system, the company says, ensures optimal performance and reliability over all operating conditions throughout its lifetime, and this functionality has now successfully passed through the required worldwide standards.
Capella is featuring live demonstrations of its products at OFC/NFOEC Booth #3713 in Anaheim, CA, from March 27-29.
