FEATURED TECHNOLOGY: SPONSORED CONTENT According to Ole Suhr, account manager
at OFS Optics, modern fibres can and should be designed to optimise the performance of the newest and most advanced transmission systems. Tese transmission systems can be power hungry, but Suhr believes it is now possible for some of the most sophisticated fibres to support power savings. He explained: ‘Te transmission system
manufacturer is always trying to squeeze more capacity into each fibre, because it’s more efficient, so it’s eventually cheaper. As a fibre producer, it is important to work together with them, trying to make fibres to support that as well as possible.’ For Suhr, an ideal solution is a single mode
fibre that has low atenuation, combined with a larger core. ‘Tat would mean,’ he said, ‘that you can basically pump more light into the fibre without geting problems. Ten you can reach longer, and are not quite as sensitive to noise. Tese two things benefit each other and help the transmission systems either transmit longer or transmit a larger capacity.’ Te company’s TeraWave ULL fibre, for
example, is a 125μm2 large area, ultra-low loss ITU-T G.654.B fibre. Its core has an effective area 49 per cent greater than G.652.D single- mode fibre, to reduce nonlinear effects that can limit reach. Its origins are interesting and, you could be forgiven for thinking, quite far removed from the metro and data centre applications that use it today. ‘You could look on it as sort of spin-off for a
submarine fibre,’ explained Suhr. ‘We have been working in the submarine area for quite some
time now, and we work with fibres that have even larger cores.’
Handle with care One of the challenges with a larger core fibre, however, is that it can prove more difficult to handle, the larger it gets. ‘Tat’s not really a problem for submarine systems,’ said Suhr, ‘because they need to be handled very specifically. But if you want to use the fibre in a terrestrial, normal, land-based transmission system, it can become more sensitive to handling.’ Tis is where the latest generation of bend-
insensitive fibres come in, and the OFS product was designed to meet and exceed the most recent G.654 recommendation – G.654.E – which was created to help improved bending performance even for fibres with an effective area as large as 125μm2. Te development was aided by the company’s experience in the development of its EZ-Bend fibre, which Suhr says ‘is the most bend insensitive fibre on the market.’ Among other sustainability benefits, the
latest generation of optical fibres, such as the TeraWave ULL, can also save power when operating the transmission systems, as Suhr went on to say: ‘If you use a fibre such as this, you will, from time to time, be able to save an amplifier, or save a line card in the transmission system. Tis means that you also save the power that would otherwise have been used for writing these components.’ But that’s not all, revealed Suhr: ‘Further to that, when you are using the fibre, it offers you

the opportunity of creating sort of a “sweet spot” for the transmission line card, especially the input side of that. Tis means that the line card can actually save power as well.’ Tat's because the line card does not have
to work so hard to correct the received signal from the fibre, thanks to its low level of non- linearities and low atenuation. Concluded Suhr: ‘We believe this is a more sustainable fibre because it allows less power use when operating the network.’ n TeraWave® ULL fibre is a registered trademark of OFS Fitel, LLC

Modern fibers should be designed to optimize the performance of the newest and most advanced transmission systems. Such systems are power hungry, but it has now proven possible for the most sophisticated optical fibers to support actual power savings of the transmission equipment. Reductions in the hunger for power could help making the internet less resource demanding – and increase the sustainability.
