Bend-Insensitive Fibres

Fibre coatings G.657 fibres have been recently developed with 200 μm and 180 µm diameter coatings featuring the same or even better performance than the legacy 250 µm coated G.652.D fibres. This offers the possibility of significantly reducing cable diameters, while achieving high fibre density. These reduced-diameter fibres have opened a gateway to innovation, opening up the potential for many new cable systems to be developed for a variety of network applications. Moreover, G.657 fibres, whatever the outside diameter (250, 200 or 180 µm), are totally compatible and spliceable to any standard G.652 fibre, a feature that makes them easy to insert into an existing network, hence also perfectly appropriate when replacing or upgrading parts of an existing optical infrastructure. Optimised performance and full compliance with legacy G.652.D fibres, coupled with enhanced protective coatings make G.657 fibres bend insensitive. The problem of macro- and microbending is virtually erased, securing the integrity of network infrastructure, increasing stability across all bands, and opening up the possibilities for systemevolution.
