AROUND THE BEND
A look at the next generation of bend-improved fibres, and how they can be used to future-proof networks
KEELY PORTWAY
THE 1625NM WAVELENGTH REALLY IS SOMETHING THAT OPERATORS HAVE TO KEEP IN MIND FOR THE NEXT GENERATION OF NETWORKS
T 26 FiBRE SYSTEMS n Issue 25 n Autumn 2019
here’s no denying that demand for bandwidth has skyrocketed in recent years, thanks largely to the increased appetite for online gaming, content
streaming and social-media use. With 5G becoming ever-closer to reality, this demand will only grow further, putting pressure on network providers and operators. It is widely acknowledged that fibre is the
best way to achieve this higher bandwidth, and deployments are happening at pace. At this year’s FTTH Conference, the latest Market Panorama figures revealed that the deployment of both fibre to the home (FTTH) and fibre to the building (FTTB) networks had increased significantly. By September 2018 it was estimated that the coverage of FTTH/B reached 46.4 per cent in EU39 countries and 36.4 per cent in EU28 countries, showing an upward trend from September 2015 where the estimated rates were 39 per cent and 27.2 per cent respectively. But is all fibre equal? According to the
International Telecommunication Union Standardization Sector (ITU-T), FTTH deployments require a dedicated single- mode fibre cable, and the latest generation of G.657 bend-improved optical fibre cables offer the flexibility for easier deployment in streets, buildings and homes, including tight corners of buildings.
Full support For Daniel Daems, fellow engineer at CommScope Connectivity, bend-improved fibres are ideally placed to support the full use of all transmission bands (O-, E-, S-, C-, L- and U-band), covering the entire wavelength spectrum, between 1260 and 1625nm – something that is particularly important for future-proofing higher capacity networks. He said: ‘At the beginning of the 90s,
everybody made products for the outside plant operating at 1310nm. Although people knew that the bandwidth of single-mode fibre was, at that time, unlimited and that longer wavelengths like 1550nm would be better
