Penbal-5

Overview

Penbal-5 is a regional submarine cable system that connects two locations within Spain: Gavá, on the mainland, and Ses Covetes, in the Balearic Islands. With a total length of 315 km, this cable serves as a vital link in Spain’s telecommunications infrastructure. It was completed and ready for service in 1994, and it is owned and operated by Telefonica, one of Spain’s leading telecommunications companies. Penbal-5 enhances connectivity between mainland Spain and the Balearic Islands, supporting both local and national communication needs.

As a relatively short regional cable, Penbal-5 plays a crucial role in ensuring reliable data transmission between the two landing points. Its establishment has been instrumental in bridging the geographical divide between the Spanish mainland and the Balearic Islands, which are a popular tourist destination and a key economic region. The cable's operation underscores Telefonica’s commitment to maintaining robust domestic connectivity.

Route and Landings

The Penbal-5 submarine cable originates in Gavá, a coastal town in the province of Barcelona, Catalonia, on the northeastern coast of Spain. Gavá’s location near the bustling metropolitan area of Barcelona makes it a strategic choice for a landing point, as it provides access to a major economic hub with significant telecommunications demand. The town is well-connected to the rest of Spain and Europe, making it an ideal gateway for data traffic.

The cable terminates in Ses Covetes, a small locality on the island of Mallorca in the Balearic Islands. Mallorca is the largest island in the Balearic archipelago and a major center for tourism, which is a key driver of the region’s economy. Ses Covetes, known for its pristine beaches, is situated in the southern part of the island. The choice of Ses Covetes as a landing point highlights the importance of providing robust telecommunications infrastructure to support the island’s residents, businesses, and visitors.

The route of Penbal-5 traverses the Balearic Sea, a section of the western Mediterranean Sea. This body of water separates mainland Spain from the Balearic Islands, making submarine cables like Penbal-5 essential for maintaining seamless connectivity. The cable’s relatively short length reflects the proximity of the Balearic Islands to the Spanish mainland, yet its role is critical in overcoming the natural barrier posed by the sea.

Ownership and History

Penbal-5 is owned and operated by Telefonica, a major Spanish telecommunications provider with a long history of developing and maintaining both domestic and international cable systems. The cable became operational in 1994, during a period of significant expansion in global and regional telecommunications infrastructure. At the time, the deployment of submarine cables like Penbal-5 was crucial for meeting the growing demand for reliable and high-speed connectivity.

Telefonica’s ownership of Penbal-5 reflects its broader strategy of investing in infrastructure to support Spain’s telecommunications needs. The company operates an extensive network of submarine and terrestrial cables, ensuring comprehensive coverage across the country. Penbal-5 is one of several cables that connect mainland Spain with its island territories, playing a vital role in the nation’s digital ecosystem.

While the cable has been in operation for nearly three decades, its current status is not publicly documented. However, its historical significance as a key link in Spain’s telecommunications network remains undisputed.

What Our Measurements Show

Our live monitoring of Penbal-5 provides insights into its operational performance. We have measured 75 distinct corridors along the cable’s route, with a best round-trip time (RTT) of 0 milliseconds and an average RTT of 127 milliseconds. These measurements indicate that while the cable is functional, its average latency may reflect the age of the system and the technology used during its deployment in 1994.

The data collected through our probes suggest that Penbal-5 continues to serve its purpose as a regional connector, facilitating communication between Gavá and Ses Covetes. The cable’s performance metrics are consistent with its design and operational context, which prioritize reliability and coverage over ultra-low latency. This is particularly important for the communities it serves, where dependable connectivity is essential for both everyday activities and economic development.

The ongoing monitoring of Penbal-5 underscores its role in Spain’s telecommunications landscape, providing valuable information for assessing its performance and planning future upgrades or replacements. While newer cables with advanced technologies may offer lower latency, Penbal-5 remains a critical component of the country’s infrastructure, ensuring connectivity across the Balearic Sea.
