The Batam Sarawak Internet Cable System (BaSICS) is a submarie cable connecting Sarawak (Malaysia) and Batam (Indonesia), spanning about 700km.

The BaSICS cable system consists of 6 fiber pairs, designed with 80x100Gbps per fiber pair, i.e. 8Tbps per fiber pairs, for a total system capacity of 48Tbps.

The BaSICS cable system is privately developed by PP Telecommunication Sdn. Bhd. (PPTel), a Sarawak-based company, with XL Xiata as its landing partner in Batam, and supplied by FiberHome as its first repeatered international subsea cable project.

The BaSICS cable system lands at PPTEL DC @Santubong 1 in Kuching, Sarawak. PPTEL DC @Santubong 1 is certified with Tier-IV Design Certification by Uptime Institute.

The BaSICS cable system has been ready for service as of June 1, 20022. It forms the shortest latency route from Sarawak to Singapore, less than 9ms between PPTEL DC @Santubong 1 and Equinix Singapore SG3.

PPTel also host the Sarawak International Internet Gateway (SIIG) at the PPTEL DC @Santubong 1.

On August 2, 2022, PPTEL announced its new corporate brand identity, "irix", to align with the transformation that is being undertaken across the organization.
