From Rio de Janeiro to Virginia

Uncategorised Leave a Comment

BRUSA, a new submarine cable operated by Telxius, and nearly 11,000 km in length is currently being laid down to link Rio de Janeiro and Fortaleza in Brazil with Virgina Beach in the US, via San Juan in Puerto Rico. This exciting new project from Telxius represents their largest infrastructural asset investment in more than a decade, and is expected to begin operations in mid-2018.


The idea for developing the cable has been prompted by surging demand not just from South America’s largest economy, where subscription-based traffic is moving into the Terabit category, but also in the wider Latin America region. Telxius are therefore anticipating the need for further extension soon after completion of the initial phase of BRUSA. The cable will be a four fibre pair open system, with one omnibus fiber pair stopping in San Juan and three fiber pairs featuring R-OADM technology dropping optical bands in San Juan and Fortaleza. The project will also include a wet plant that has been designed to support at least 13.5 Tbps per fiber pair, including with OADM units. Further specification details include a power feed system that will supply power to the submerged repeaters. This is designed to provide a stable D.C current, optimise space utilisation within the Terminal Station, and provide full alarm functionality, with monitoring circuits and safety features. It will also provide real-time information to the supervisory team.

The repeaters themselves should prove to be reliable over a 25-year time span thanks to the high
quality 980nm pumps. They will also be compatible with C-OTDR to increase measurement accuracy of a fault location and have ultra large optimal bandwidth to maximise the system capacity.
Unlike certain other cable projects (including those of Telxius) which land in Sao Paolo, the point of
landing BRUSA in Rio de Janeiro is to give diversity of access to Brazil and to tap into a metropolis
which has been growing over recent years into a large technological hub.

In the US, meanwhile, the cable lands at Virginia Beach, where a growth in government infrastructural capacity is causing a surge in demand for OTT. From this landing point access is also given to the technology corridor between New York, Virginia and North Carolina.

We asked what challenges Telxius have faced thus far in executing the project. Roberto responded that thanks to their many years of experience (20 years, in fact) operating in the area, and having built a number of cables already such as the SAm-1 Cable System in 2001, they possess a deep understanding of the needs of the region as well as a sound geographical knowledge. Owing to this they have thankfully not encountered any major issues in the deployment process thus far. Fingers crossed this remains the case!

We look forward to hearing much more about this project, and wish Telxius success.
