Epic Malta-Sicily Cable System (EMSCS): connecting Malta and Sicily
The Epic Malta-Sicily Cable System (EMSCS) is a submarine telecommunications cable linking
Balluta Bay in Malta to
Catania in Sicily, Italy. At 260 km in length, it serves as a key infrastructure for connectivity between Malta and mainland Europe, facilitating data traffic and supporting telecommunications services. The cable is owned by Epic, a telecommunications operator active in Malta.
What makes EMSCS noteworthy is its relatively short route, which minimizes latency compared to longer submarine cables. However, several technical details about the cable remain undisclosed, including its design capacity, number of fiber pairs, and supplier. This lack of public information limits the ability to fully assess its technological specifications and operational capabilities.

Route
The EMSCS connects Balluta Bay in Malta to Catania in Sicily, Italy. Balluta Bay is located on Malta's northeastern coast, while Catania is situated on the eastern coastline of Sicily. This route spans approximately 260 km across the Mediterranean Sea. Catania serves as a major landing hub for submarine cables, hosting several other systems, including IMEWE, Italy-Malta, MedNautilus Submarine System, and SeaMeWe-5. This makes Catania a critical node for international connectivity in the Mediterranean region.
Why it was built and what it carries
The EMSCS was constructed to enhance Malta's connectivity to mainland Europe, addressing the growing demand for international bandwidth and reliable telecommunications services. As Malta is an island nation, submarine cables are essential for linking its telecommunications infrastructure to the broader global network. While specific data about the cable's capacity and traffic are not publicly disclosed, it is reasonable to assume that EMSCS carries internet, voice, and data traffic for residential, business, and governmental users.
History: what can be established
The GeoCables database records the EMSCS as ready for service in 2004. No conflicting industry sources were identified to suggest a different commissioning year. Epic, the cable's owner, is a telecommunications operator active in Malta, but detailed historical information about the cable's construction, suppliers, or upgrades is not publicly available.
Capacity and technology
Publicly available records do not disclose the design capacity, number of fiber pairs, or the supplier for EMSCS. Without operator documentation, it is impossible to determine the cable's technological specifications or its ability to support future bandwidth demands. Submarine cables typically use dense wavelength division multiplexing (DWDM) technology to maximize capacity, but attributing this to EMSCS without evidence would be speculative.
Latency: the physics
The computed one-way light propagation latency for the 260 km wet segment of EMSCS is approximately 1.3 ms, with a theoretical round-trip time (RTT) floor of 2.5 ms. However, real-world latency measurements are significantly higher due to additional factors such as land tails, terminal equipment, and routing inefficiencies.
Live measurements from remote probes show end-to-end RTTs between Balluta Bay and Catania ranging from a minimum of 40.0 ms to an average of 78.0 ms. The reverse path measurements (Catania to Balluta Bay) show a minimum of 65.3 ms and an average of 73.9 ms. These values reflect the full internet path rather than the cable alone, including delays introduced by terrestrial networks and intermediate routing.
Redundancy: what happens if it breaks
Catania hosts multiple submarine cables, including IMEWE, Italy-Malta, MedNautilus Submarine System, and SeaMeWe-5. These systems provide alternative connectivity routes in case of a failure on EMSCS. Submarine cable repairs typically involve specialized ships equipped with remotely operated vehicles (ROVs) to locate and fix faults. While repair times can vary widely, the presence of redundant cables at Catania mitigates the risk of prolonged outages for Malta's international connectivity.
Bottom line
- EMSCS connects Malta (Balluta Bay) to Sicily (Catania) over a distance of 260 km.
- Owned by Epic and recorded as ready for service in 2004.
- Design capacity, fiber pairs, supplier, and technology are not publicly disclosed.
- Computed latency for the wet segment is 1.3 ms one-way, but live measurements show much higher end-to-end RTTs.
- Catania's multiple cable systems provide redundancy in case of failure.
