Bragg gratings pass Telcordia assessment demonstrating long-term reliability for 25 years' use in controlled environments
Southampton Photonics successfully completed an independent conformance analysis performed by Telcordia Technologies for its family of fibre Bragg gratings (FBGs).
Telcordia Technologies, the world's largest provider of network software, consulting and engineering services to the telecommunications industry, concluded that SPI's FBGs qualify for 25-year service life applications in controlled environments.
SPI's FBGs are used in WDM systems to allow more wavelengths to be added, dropped, or muxed per fibre and therefore providing more total bandwidth per fibre with improved flexibility and scalability.
The 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 -5C to +70C.
SPI's business development director Stuart Woods commented, "We have always been confident in the quality of our products and Telcordia qualification of our products is a further step in SPI's overall business and manufacturing execution - proving our market leadership as a volume supplier from grating foundry to complete grating solutions." 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 commence qualification of modules this quarter.
