Sistem Kabel Rakyat 1Malaysia (SKR1M): Domestic connectivity for Malaysia
The Sistem Kabel Rakyat 1Malaysia (SKR1M) is a submarine cable system designed to enhance domestic connectivity within Malaysia. Spanning approximately 3800 km, it links multiple key locations across Peninsular Malaysia and East Malaysia, including
Cherating,
Mersing,
Bintulu,
Kota Kinabalu,
Kuching, and
Miri. The cable is owned jointly by TIME dotCom and Telekom Malaysia, two prominent telecommunications providers in the country. As of the GeoCables database, SKR1M has been listed as in service since 2017.
What makes SKR1M particularly notable is its role in bridging the connectivity gap between East and West Malaysia, a challenge posed by the country's geography. However, several technical details about the cable, such as its design capacity, fiber pair count, supplier, and technology, remain undisclosed in publicly available sources. This lack of transparency leaves room for speculation but prevents definitive conclusions about its operational capabilities.

Route
SKR1M connects six landing points across Malaysia, strategically chosen to provide coverage for both Peninsular Malaysia and East Malaysia. The landing points are:
- Bintulu, Sarawak
- Cherating, Pahang
- Kota Kinabalu, Sabah
- Kuching, Sarawak
- Mersing, Johor
- Miri, Sarawak
The corridor spans the South China Sea, a critical maritime region for Malaysia's domestic submarine cable systems. Cherating and Mersing serve as the main entry points on the peninsula, while Bintulu, Kota Kinabalu, Kuching, and Miri provide connectivity to East Malaysia.
Why it was built and what it carries
SKR1M was built to improve domestic internet and telecommunications infrastructure in Malaysia. By connecting East Malaysia (Sabah and Sarawak) with Peninsular Malaysia, the cable addresses the need for higher bandwidth and lower latency between these regions. This is particularly important for Malaysia's economic development, as it supports internet access, enterprise connectivity, and government services across geographically dispersed areas.
While the cable's specific design capacity is not publicly disclosed, it is likely intended to handle both consumer and enterprise traffic, given the ownership by major telecom operators TIME dotCom and Telekom Malaysia. SKR1M complements Malaysia's broader network of submarine cables, which also connect internationally.
History: what can be established
The GeoCables database records SKR1M as ready for service in 2017. No conflicting dates have been identified in industry sources, suggesting general consensus on its operational timeline. However, details about its construction, such as the supplier or specific milestones during deployment, are not publicly documented.
SKR1M's development aligns with Malaysia's efforts to modernize its telecommunications infrastructure and reduce reliance on international cables for domestic traffic.
Capacity and technology
Publicly available sources do not disclose SKR1M's design capacity, fiber pair count, or the specific technology used in its construction. Without operator documentation, attributing these characteristics would be speculative. Given its domestic focus, the cable likely employs modern optical transmission technologies, but the absence of detailed specifications limits further analysis.
Latency: the physics
The theoretical one-way light propagation latency over SKR1M's 3800 km wet segment is approximately 18.6 milliseconds, with a round-trip time (RTT) floor of 37.3 milliseconds. This calculation assumes light traveling through fiber at speeds ranging from 200,000 to 204,000 km/s.
Real-world latency measurements, however, would be higher due to additional factors such as land tails, terminal equipment processing, and network routing. No live measurements for SKR1M are currently available in GeoCables data.
Redundancy: what happens if it breaks
If SKR1M experiences a fault, redundancy for domestic traffic between East and West Malaysia would depend on other cables landing at shared points. Notable alternatives include:
Repair logistics for SKR1M would follow standard industry practices, including deploying cable ships to locate and fix the fault. Given the regional importance of the cable, repairs would likely be prioritized to minimize service disruption.
Bottom line
- SKR1M is a domestic submarine cable connecting Peninsular Malaysia and East Malaysia.
- Spanning 3800 km, it has been in service since 2017, according to GeoCables data.
- Owned by TIME dotCom and Telekom Malaysia, but technical details such as capacity and fiber pairs are not disclosed.
- Theoretical latency is approximately 37.3 ms RTT for the wet segment, though real-world values are higher.
- Redundancy is provided by other cables landing at shared points, ensuring continuity in case of faults.
