MViSTA

Overview

The MViSTA submarine cable system is a critical telecommunications infrastructure linking five key locations in Southeast Asia: Pengerang (Malaysia), Rayong (Thailand), Songkhla (Thailand), Tuas (Singapore), and Vung Tau (Vietnam). Designed to enhance connectivity and support growing data demands in the region, MViSTA facilitates high-speed data transmission across these countries. With its strategic route, the cable plays a vital role in fostering economic growth, improving digital access, and enabling technological development in the connected areas.

Spanning diverse maritime environments, MViSTA traverses the South China Sea and the Gulf of Thailand, two important bodies of water in the region. These seas are known for their heavy shipping traffic and complex underwater geography, which pose engineering challenges for submarine cable deployment. Despite these challenges, MViSTA has been successfully installed to provide reliable and efficient communication services to millions of users in Southeast Asia.

Route and landings

The MViSTA cable connects five landing points strategically located in Southeast Asia. Starting from Pengerang in Malaysia, the cable crosses the South China Sea to reach Tuas in Singapore, a major hub for international telecommunications. From Singapore, the cable extends to Vung Tau in Vietnam, a coastal city known for its growing industrial and economic significance.

In Thailand, MViSTA makes landfall at two locations: Rayong and Songkhla. Rayong is a key industrial area on the eastern seaboard, while Songkhla, located in southern Thailand, serves as an important regional center for trade and commerce. These landing points were chosen to maximize regional connectivity and provide robust links to major economic zones. The route’s design considers both geographic proximity and the need to connect diverse economic centers, ensuring the cable serves as a backbone for digital infrastructure in the region.

Ownership and history

Details regarding the ownership and operational history of the MViSTA cable system remain sparse. However, its deployment reflects the growing demand for enhanced connectivity in Southeast Asia, a region experiencing rapid digital transformation and economic growth. The cable’s installation aligns with broader efforts to improve telecommunications infrastructure in the area, supporting industries such as finance, manufacturing, and technology.

The selection of landing points suggests collaboration between multiple stakeholders to address regional connectivity needs. Pengerang, Tuas, Vung Tau, Rayong, and Songkhla are all strategically significant locations, each contributing to the cable's role in linking industrial, commercial, and urban centers. The MViSTA system represents a step forward in meeting the region's increasing bandwidth requirements and fostering international cooperation in telecommunications.

What our measurements show

Our live monitoring of the MViSTA cable system reveals performance across six measured corridors. The fastest recorded round-trip time (RTT) is 7 milliseconds, indicating excellent latency for high-speed data transmission. On average, RTT across the cable measures 190 milliseconds, reflecting variability influenced by distance, network congestion, and routing factors.

These measurements highlight the cable’s efficiency in connecting key locations, particularly for time-sensitive applications such as financial transactions and cloud computing. The low latency between certain endpoints, such as Tuas and Pengerang, underscores the cable’s capability to support high-performance data services. However, the higher average RTT suggests room for optimization to ensure consistent performance across all corridors.

By providing reliable data on latency and connectivity, our probes contribute to understanding the cable’s operational characteristics and its impact on regional telecommunications. MViSTA’s performance metrics underline its importance in supporting Southeast Asia’s growing digital economy.
