Minoas East and West: A Greek Submarine Cable System
The Minoas East and West submarine cable system is a 270-kilometer fiber-optic network connecting
Neapoli and
Nopigeia, both located in Greece. Owned and operated by Grid Telecom, the cable is listed as in service and was recorded in the GeoCables database as ready for service in 2021. However, public details about its design capacity, fiber pair count, supplier, and technology are not disclosed, limiting deeper technical analysis.
What stands out about Minoas East and West is its exclusive focus on domestic connectivity within Greece, a relatively short distance for submarine cables. This suggests its primary role is likely to enhance regional telecommunications infrastructure, rather than serving as an international transit route. The absence of publicly available live latency measurements or detailed specifications leaves room for speculation about its performance and technological features.

Route
The Minoas East and West cable system connects two landing points: Neapoli and Nopigeia, both situated on the Greek mainland. Neapoli lies in the southern part of Greece, while Nopigeia is located in the western region. The cable spans 270 kilometers, making it a relatively short submarine system designed for domestic connectivity rather than long-haul international traffic. This route likely serves to improve telecommunications resilience and capacity within Greece, particularly in areas where terrestrial networks may face limitations.
Why it was built and what it carries
The primary purpose of Minoas East and West appears to be strengthening Greece's domestic telecommunications infrastructure. By connecting Neapoli and Nopigeia, the cable likely facilitates high-speed data transfer between these regions, supporting local internet service providers, enterprise networks, and potentially government communications. As a domestic cable, it is unlikely to carry international transit traffic, focusing instead on regional connectivity and redundancy.
Given the lack of publicly disclosed design capacity or fiber pair count, the exact volume of data the cable can handle remains unknown. However, the involvement of Grid Telecom, which specializes in telecommunications infrastructure, suggests the cable was built to meet growing demand for reliable, high-speed connectivity within Greece.
History: what can be established
The GeoCables database records Minoas East and West as ready for service in 2021. No alternative dates have been surfaced from industry sources, so there is no apparent conflict regarding its operational timeline. However, the absence of detailed historical documentation or announcements from Grid Telecom limits the ability to trace its development, procurement, and installation phases. Standard industry practices for submarine cable deployment would have included marine surveys, cable laying, and burial operations to protect the cable from external damage.
Capacity and technology
Publicly available data does not disclose the design capacity, fiber pair count, supplier, or specific technology used in the Minoas East and West cable system. Without operator documentation, attributing these characteristics would be speculative. It is reasonable to assume that the cable employs modern fiber-optic technology, given its recent ready-for-service date in 2021, but the exact specifications remain unknown.
Latency: the physics
The computed one-way light propagation latency for Minoas East and West is approximately 1.3 milliseconds over its 270-kilometer length. This theoretical figure assumes light travels through fiber at speeds between 200,000 and 204,000 kilometers per second. The round-trip time (RTT) for the wet segment alone is calculated at approximately 2.6 milliseconds. However, real-world latency measurements would be higher due to additional factors such as signal processing delays, routing through terminal equipment, and the land tails connecting the cable to broader networks.
No live latency measurements are currently available for this cable, and any claims about its real-world performance would require direct testing or operator disclosures.
Redundancy: what happens if it breaks
In the event of a failure in the Minoas East and West cable system, redundancy would depend on alternative connectivity options within Greece. While the specific alternatives are not detailed in the GeoCables database, Greece's telecommunications infrastructure includes terrestrial fiber networks and other submarine systems that could potentially reroute traffic. Repairing the cable would follow standard industry procedures, including deploying specialized cable ships to locate, retrieve, and repair the damaged section.
Bottom line
- Minoas East and West is a 270-kilometer domestic submarine cable connecting Neapoli and Nopigeia in Greece.
- Owned by Grid Telecom and recorded as ready for service in 2021.
- Design capacity, fiber pairs, supplier, and technology are not publicly disclosed.
- Computed latency for the wet segment is approximately 1.3 ms one-way and 2.6 ms round-trip.
- The cable enhances regional connectivity within Greece, but its exact capabilities remain unclear due to limited public documentation.
