Without revealing too much of your work plan, what can we expect from the D&O committee in 2023?

The purpose of the Deployment & Operations committee is to provide the Members of the FTTH Council Europe with expert insights into the latest innovations and trends animating the fibre industry. We regularly organize webinars and produce white papers, often consisting of a high-level technological overview coupled with a practical business case. Our aim is to provide our members with an answer to the important question: “Interesting, but what’s in it for me?”.

Topics of interest for this year center around the role of IT in the future end-to-end process of a fibre operator, from design to deployment, over operation, but even touching upon finance and budget aspects. The vision of the Deployment & Operations committee has always been that the fibre network is an important asset, that should be leveraged as much as possible. As a result, we have outlined how the business case for wireless-wireline convergence is self-evident. This year, we will try to go a step further by showcasing some technological improvements to remove some of the bottlenecks that have slightly held this convergence back, discuss how XGS-PON is ready to support 5G back- and midhaul, and analyse how newer fiber technologies can add fronthaul to this list as well.

In line with this mission, this year’s Deployment & Operations committee workshop at the FTTH Conference will be focusing on the theme of “Fibre for Everything”, supporting the wider sentiment of the council that we should extend the scope beyond FTTH. Past workshops from the committee have always been excellently received and well attended. They provide an opportunity for technical experts to come together and discuss the latest trends they expect to see at the show.
 

The D&O committee is responsible for the publication of the FTTH Handbook: how did it become such an important resource for the fibre community?


Our flagship deliverable is indeed the FTTH Handbook. The main attraction of this resource is the fact that it is a regularly updated manual that comprises an end-to-end knowledge overview of all aspects related to the fibre industry, from planning, to building and operating highly efficient, future-proof, automated fibre networks. As such, it encompasses a very broad scope of subjects, but it also goes into the details of everything it touches upon, thanks to the multiple reviews and updates which this asset has gone through over more than a decade. For the near future, our plan is to update fewer sections of the FTTH Handbook, but more frequently than what has been done in the past. Please expect some updates around aerial fibre infrastructure this year around!


 

What are your views regarding the evolution of FTTH technology?

We have seen a spectacular increase in the deployment of fibre networks over the past years. This has mainly been driven by the realization that investments in physical infrastructures continue to pay back well beyond the typical investment horizon operators had been using in the past. When considering a longer time horizon, going for a future-proof technology, that is easy and cheap to maintain and operate, is the real key. Fibre therefore becomes an easy choice, and the innovation in FTTH technologies is continuing. I expect the active components to move forward and cost-effectively support even higher data rates. From a use case perspective, I expect fibre to extend beyond FTTH, moving into the enterprise, industry, wireless backhaul, and much more. From the passive side, I expect solutions that continue to help operators bring down operating costs. This is also the case for innovations around cloud-native management of these networks.
 

Generally speaking, what is the profile of the companies joining the D&O committee?


The members of our committee are interested in the fundamentals of the industry they are working in. Most of them are technical experts in one specific field, and are keen on sharing their knowledge with others, but also learning from others. For the future, I would very much welcome some additional operator members to join the committee, as this part of the value chain is less represented than others. Hearing the point of view of operators would be extremely enriching for the Deployment & Operations committee, as telecom operators are ultimately those running and operating the technology we are making available.

Finally, the ultimate benefit of taking part in the activities of the Deployment & Operations committee is to acquire and share cross-knowledge oh how an FTTH network work and will work in the future, from a wide range of technical experts, or experts-to-be.

Use of a ground water heat pump (GWHP) to cool FTTx street cabinets

Member company: Eurofiber
Country or geographical scope: Global
Period: 2015-
Segment of the value chain concerned: Internet service provider
Product/service category involved: Street Cabinets

Abstract:
ISP’s can achieve significant reductions in their energy usage, and thereby reduce their greenhouse gas emissions, by switching to GWHPs to cool their street cabinets, rather then using conventional air conditioning. In addition GWHPs require less maintenance reducing the amount of truck rolls needed for service.


Context

As a sector we are well aware that every party has a responsibility to reduce their carbon footprint. Digital services are often a way to reduce the need for travel or transport of physical goods. However digitization itself is not currently free of its own impact on the environment. Therefor as a sector we must act to reduce our own footprint as well. We cannot however do this alone and we believe that by sharing best practices we can help and inspire others to go beyond their current efforts, ultimately to the benefit of all society.
 

Solutions

Active equipment used by the broadband service can require cooling to ensure uninterrupted service. Traditionally this has been done by using conventional air conditioning. This is an effective method of cooling, however it requires addition power, and thus carbon emissions. An alternative that has been used by Eurofiber for its street cabinets is to cool them by using a ground water heat pump (GWHP) instead. What a GWHP does is to keep the air in the street cabinet stable by pumping up ground water from a well deep in the earth. The temperatures there are relatively stable at around 15 °Celsius year round. By pumping this water through a heat exchanger the GWHP can cool during the summer and provide heat during the winter, which also eliminates the need for a separate heater. A GWHP has a very low energy consumption and requires little maintenance, which reduces their footprint further by reducing the amount of truck rolls.
 


 

Results

Eurofiber has been able to use GWHP systems to cool some of their street cabinets. Given the need to dig fairly deep to reach ground water of the correct temperature this is not always feasible. Where it is possible it works very well though, energy consumption at peak is only 3% of what a conventional air conditioned street cabinet would use and maintenance costs are much lower, making it an ideal solution.
 

Conclusions

As enablers of digitization the broadband sector is already doing much to help other reduce their footprint. We must however as a sector do more and also look at our own footprint. An important step in this is the transition to full fiber networks. However even fiber networks use active equipment that requires cooling. The example of using ground water heat pumps is an example of how we can reduce our own carbon footprint by both reducing our energy usage and reducing the need for maintenance.
