Frequently asked questions about the SJC2 cable
SJC2 connects Singapore with Japan via Vietnam, Cambodia, Thailand, Hong Kong, Taiwan, South Korea and several landing points in China. In total the system comprises eleven landing stations in nine countries and territories. Cambodia is connected to a submarine cable for the very first time through SJC2.
SJC2 offers a total capacity of 144 Tbit/s across eight fiber pairs, each with 45 wavelengths at 400 Gbps. That is around five times the capacity of its predecessor SJC. The system was built by NEC as turn-key supplier.
SJC2 went into operation in July 2025, making it the most modern APAC cable system in active use. It uses current 400G DWDM coherence technology. For companies on the Japan to Singapore axis it is currently the highest-capacity option.
It depends on capacity needs, site mix and redundancy. SJC2 offers the highest capacity with 400G, SJC a particularly earthquake-resistant route and APG an established backbone with broad country coverage. SAVECALL compares the systems vendor-neutrally and often recommends a combination rather than a single cable.
True resilience only comes from physically separate systems, not from two carriers on the same cable. SJC2 can be combined deliberately with APG, SJC or newer systems such as ADC into diverse routes. SAVECALL checks where your existing connections physically overlap and plans an independent second route.
Companies get capacity on SJC2 through direct contracts with the consortium members, not through reseller chains. SAVECALL negotiates IRU structures and leased capacity models directly, benchmarks transparently against SJC, APG and other APAC options and plans redundancy at the same time.
