Indonesian telecoms infrastructure and network provider MoraRepublic and Chinese subsea cable firm HMN Tech announced on Thursday that they have completed factory acceptance testing of wet plant gear for the Moratelindo International Cable System-3 (MIC-3).

The MIC-3 subsea cable aims to connect Singapore and Batam, deploying two 32FP branching units along the route. As part of the project, HMN will deploy two of its 32FP branching units, each of which are equipped with 16FP optical switch technology. The branching units will enable MoraRepublic to expand MIC-3 to other potential destinations, such as Jakarta.

HMN said its optical switching technology will enable MIC-3 to support flexible future access for two 16FP systems, enabling precise and flexible switching between trunk and branch segments, as well as the ability to adapt to incremental bandwidth requirements, providing ample scalability to meet future demand.

MoraRepublic – formerly known as Moratelindo before it struck a deal to merge with MyRepublic Indonesia at the end of 2025 – said MIC-3 will promote the interconnection of digital infrastructure within the Singapore–Johor–Batam corridor and support growth of AI and data centres in Southeast Asia.

“The MIC-3 submarine cable project is a key strategic initiative for regional digital interconnection,” said MoraRepublic CTO Michael C. McPhail in a statement. “It provides a high-capacity gateway for Indonesia to connect to Singapore, effectively achieving high-capacity network coverage on a broader scale in the future via its reserved flexible branching capabilities, bringing new vitality to the development of the regional digital economy.”

MIC-3 is one of several subsea cable systems being built along that route. Telkom Indonesia’s international arm Telin is developing the Nongsa-Changi subsea cable in partnership with BW Digital, as well as the Indonesia Singapore Cable System (INSICA) in partnership with Singtel.
