| Corning Inc., USA, a world-leading supplier of optical fibre, has announced the global conversion of its standard single-mode fibre product portfolio to Corning� SMF-28e� optical fibre, the industry�s most widely demanded low-water peak optical fibre. The company also announced significant advancements in both optical and geometry specifications for SMF-28e fibre. Corning has now established SMF-28e fibre as the successor product to SMF-28� optical fibre. SMF-28e fibre, an ITU-T G.652.C- and D-compliant fibre provides both tighter specifications and full-spectrum capability required by today�s carriers, while carrying forward all of the advanced attributes that customers have come to expect from the various products included in the Corning SMF-28 fibre family. First introduced and accepted by customers in 2001, SMF-28e fibre is compliant to all major industry standards and is compatible and fully inter-operable with legacy single-mode networks.
Enhanced specifications for SMF-28e fibre in the areas of attenuation, dispersion and cladding non-circularity have been introduced last September. Corning has lowered the SMF-28e fibre attenuation specification by up to 9% for three major operating windows, allowing greater application design flexibility. Furthermore, the company has improved both the specified dispersion limits and the maximum zero-dispersion slope values, providing operators with added network planning reliability across multiple transmission bands in today�s emerging applications. Finally, SMF-28e fibre now has more stringent geometry specifications for cladding non-circularity, delivering even greater ease of installation and handleability through improved fibre splicing and connectorisation performance. All Corning SMF-28e optical fibres are now being manufactured to these enhanced specifications.
