Slide 1: Unrepeatered systems – why, what, when?
Unrepeatered systems – why, what, when? Submarine Networks World 2020 Anders.Ljung@hexatronic.com
Slide 2: When are unrepeatered systems deployed?
When are unrepeatered systems deployed? • Short point-to-point links between countries, regions & islands • To provide telecoms connectivity to an oil platform, off-shore wind facility, etc. • Where a festoon system makes better economic sense than a terrestrial one • To increase local connectivity
Slide 3: Power to the unpowered!
Power to the unpowered! • The unrepeatered market is not very well represented within the subsea community Lack of data recorded and reported. Hard to come by regional data, pricing and statistics Lack of debate or discussion – new customers do not have a very clear idea about the unrepeatered s

Recent market updates – courtesy of Submarine Telecoms Forum • 33 publicly announced unrepeatered systems put into service 2016-2020 2019 was particularly busy for new unrepeatered builds 2020 saw a slow down presumed to be COVID related – 13 were published as planned for 2020 but will likely go R

Slide 8: Pros and Cons of Unrepeatered Systems
Pros and Cons of Unrepeatered Systems Pros Cons • Passive technology, no complex powering • Distance limited required* • As unrepeatered spans get longer more • High fibre count – 192 fibres and more expensive fibre is required Simple fibre pair sale business model • Longer spans require remote opt
Slide 9: To repeat or not to repeat?
To repeat or not to repeat? • Distance constraints typically drive the choice between unrepeatered and repeatered systems • Studies by Xtera and Hexatronic showed that currently the economic tip over point is around 450km Price of fibre / cable / repeaters / ROPA / PFE all need to be considered •
Slide 10: Let’s talk about distance!
Let’s talk about distance! Capacity with 0.16 dB/km fibre attenuation, 1 dB operating margin, 3 dB repair margin and 0.005 dB/km ageing 100 90 80 Number of 100G channels 70 60 50 40 30 No ROPA ROPA 80µm 20 ROPA 110µm 10 0 300 350 400 450 500 Length (km) Data courtesy of Xtera
Slide 11: The whole range - from capacity to connectivity
The whole range - from capacity to connectivity • Easy to achieve high capacity only over short links with almost any equipment – whilst bridging very long distances even with small capacity is hard – and costly • What’s needed depends on the application, e.g. high capacity for data centres or conne
Slide 12: Other Markets – Living in Harmony?
Other Markets – Living in Harmony? • The seabed is currently occupied by Submarine fiber optic telecoms cables Submarine power cables (interconnectiors) Submarine power cables (export and inter array cables) Offshore wind farms Oil & Gas platforms Pipelines and umbilical's Out of service asse
