The presentations will address the following topic areas and will bring the attendee up to speed on the latest trends and debates in this sector.

Review of System Types

The Master Class will first outline the types of usages and key performance requirements which vary from Repeatered Systems (Repeaters and Branching Units), Unrepreatered Systems (inc, High Fibre Count Cable and ROPA’s), and will also outline the evolution of transmission technology which dominates wet plant design.


After 2 decades of relatively little technical churn we are now looking at a range of exciting options for the future. Wideband repeaters with C+L technology and high fiber count repeaters will provide solutions for huge capacity demands. Long span repeater with narrow band is an economic solution for regional systems. SDM technology such as multi-core will be one of the breakthrough technologies for the capacity crunch.  The attendees will be taken through the latest developments in this area

Branching Units

Similar to the Repeaters, the Branching Unit requirements are changing massively as Terrestrial Technologies functionality starts to impinge on Submarine Systems, in particular the need for greater wavelength agility. Reliability and housing layout are the watchwords here. The presenters will bring the latest thinking on component reliability and housing layout considering installation design to the fore.


The cable is the most major portion of the wet plant. Recent demands for both capacity and economy stimulates evolution of cable as well as repeaters.  The presenters will present the latest development and the futures perspectives.
