FirstPath had a requirement – the highest capacity underwater cable possible and Prysmian were
Given the huge expense and complexity of underwater cable deployment, coupled with rising fibre
demand, FirstPath needed a new underwater solution. The cable needed to be small and lightweight
for easy installation but also offer the highest possible fibre capacity.
Prysmian were up to the challenge. Their latest design combines Prysmian’s award-winning
Bendbright-XS fibre with advanced FlexTube cable technology, to create an incredibly fibre dense
“This installation is a major step forward for FirstPath and further expands our network
infrastructure enabling us to tackle the challenges of increasing fibre demand”, says FirstPath CEO
Stephen Carter. “The ability to more than double the installed fibre capacity for almost the same
installation cast of the typical 312 fibre underwater cable was a very attractive offering from
Prysmian. Their outside of the box thinking was a perfeet fit for our company’s needs”.
The installation presents a first for both companies. FirstPath’s first underwater cable deployment
and Prysmian’s highest fibre-count underwater cable. “This innovative approach provides 720 fibre
cores in the same form factor as a conventional 312 fibre solution. This lowers the total cost of
ownership, providing over double the fibre capacity per cable for the same installation costs. This
way we can provide even more value to our customers” says Alice Codenotti, Telecom Account
Manager at Prysmian.
Prysmian has Iong been a leader in harbour-crossing cables. This latest offering pushes the
boundaries of cable technology and manufacturing. The project required the collaboration of
multiple R&D centres within Prysmian group. In just six months after initial consultation Prysmian
were able to design, manufacture and deliver a solution to meet FirstPath’s needs. The cable was
installed under the Sydney Harbour Bridge, providing two separate cross-harbour links to add to
FirstPath’s ever growing fibre network.
