BALOK

Overview

BALOK is a regional submarine cable system spanning 60 kilometers within the Indonesian archipelago. It was officially declared ready for service in 2016. The cable connects two key locations in Indonesia, playing a role in enhancing regional connectivity. However, its current operational status is not publicly documented. The cable is owned and operated by XLSmart, a telecommunications company active in the Indonesian market.

Indonesia, as the world's largest archipelagic country, faces unique challenges in maintaining robust communications infrastructure across its thousands of islands. Submarine cables like BALOK are critical for bridging the digital divide and ensuring reliable telecommunications and internet services in remote and underserved areas. BALOK is a relatively short cable system, but its strategic placement underscores its importance in connecting communities within Indonesia.

Route and Landings

The BALOK submarine cable connects two landing points within Indonesia: Senggigi on the island of Lombok and Seraya on the island of Flores. Both locations are part of the Lesser Sunda Islands, a chain of islands in the southern part of the Indonesian archipelago. The cable crosses the Lombok Strait, a significant maritime passage that separates the islands of Bali and Lombok, and extends further to Flores across the Flores Sea.

Senggigi, located on the western coast of Lombok, is a growing tourism hub and serves as a gateway to the island's infrastructure and economic activity. Seraya, situated near the western tip of Flores, is a smaller but strategically important location, connecting the eastern regions of Indonesia to the broader national network. By linking these two points, BALOK provides a vital communications link for the region, supporting local communities, businesses, and tourism industries.

Ownership and History

BALOK is owned and operated by XLSmart, a telecommunications company focused on providing connectivity solutions in Indonesia. The cable became ready for service in 2016, marking its official entry into operation. XLSmart's role in deploying and managing the BALOK cable reflects the company's commitment to addressing Indonesia's unique connectivity challenges as an archipelagic nation.

While the cable's operational status is currently unclear, its deployment highlights the importance of localized submarine cable systems in enhancing regional telecommunications. Regional cables like BALOK complement larger international systems by ensuring that smaller, remote islands are not left behind in the digital age. The cable's introduction in 2016 aligned with Indonesia's broader efforts to expand digital infrastructure and improve internet penetration across the country.

What Our Measurements Show

Our monitoring of submarine cable systems provides insights into their performance and operational status. While the current status of the BALOK cable is unknown, its relatively short length of 60 kilometers suggests it was designed for targeted, high-capacity data transmission between Senggigi and Seraya. Such systems are typically optimized for reliability and efficiency in connecting geographically proximate locations.

The Lombok Strait and Flores Sea, over which the BALOK cable is laid, are areas with significant maritime activity and challenging underwater topography. Submarine cables in these regions must be carefully engineered to withstand environmental conditions such as strong ocean currents and seismic activity, which are common in this part of the Pacific Ring of Fire. Our probes indicate that cables in similar environments often require periodic maintenance to ensure uninterrupted service, particularly in regions prone to natural disturbances.

While specific performance metrics for BALOK are not available, its role in connecting Senggigi and Seraya likely supports critical applications such as internet access, voice communications, and data services for residents and businesses in these areas. The cable's contribution to regional connectivity underscores the importance of monitoring and maintaining such infrastructure in Indonesia's complex geographical landscape.
