13 September 2002 -- UK-based SPI (Southampton Photonics Inc) has completed an independent conformance analysis performed by Telcordia Technologies for its family of fibre Bragg gratings (FBGs). Telcordia Technologies concluded that SPI's FBGs qualify for 25-year service life applications in controlled environments.
SPI's FBG family comprises 25, 33, 40 and 50GHz channel spacings for OADM and mux applications. They are athermally packaged to provide absolute wavelength accuracy of ±0.02nm over the full operating temperature range of -5oC to +70oC.
Random samples were measured by SPI at its internal test laboratory and at accredited third-party test laboratories in the UK and Germany. The FBG family was tested for long-term reliability, environmental endurance, operating temperatures, flammability and failure rate and passed on all accounts.
SPI is continuing the Telcordia approval process of all of its products and will start qualification of modules this quarter.
