Awards for Outstanding Performance
Technology & capacity
SJC was jointly supplied by TE SubCom and NEC Corporation and has six fiber pairs with OADM branching technology.
- 6 fiber pairs: 28 Tbit/s design capacity after 100G upgrade of SLTE equipment
- OADM technology: Optical add-drop multiplexing at the branch points for flexible capacity allocation
- Earthquake-proof routing: deliberate routing away from seismically active zones
- Direct Unity connection in Chikura: Lowest available latency on the Singapore-Los Angeles route
Provider Overview
SAVECALL as access to SJC
SJC is the first choice for companies that want to connect Japan, Hong Kong and the ASEAN region via a resilient, low-latency system. The earthquake-resistant routing and direct Unity connection in Chikura make SJC technically the most compelling option for latency-sensitive applications on this axis. SAVECALL has direct partnerships with the relevant consortium partners and sources capacity on SJC without detours. We compare the available options on SJC, APG and SJC2 and recommend the combination that suits your site mix and redundancy requirements. This is not standard advice. This is market access.
The result for our customers:
- Direct capacity access to SJC without reseller chains
- Negotiation of IRU structures and leased capacity models
- Transparent price benchmarking against all available alternatives
- True route diversity through independent redundancy planning
- Clear SLAs and ongoing capacity management

Frequently asked questions about the SJC cable
SJC connects Chikura in Japan with Shantou in China, Chung Hom Kok in Hong Kong, Nasugbu in the Philippines, Telisai in Brunei and Tuas in Singapore, with an optional extension to Songkhla in Thailand. For companies with sites in Japan, Hong Kong or the ASEAN region, SJC offers one of the longest-established, most resilient intra-Asian routes.
SJC reaches a design capacity of 28 Tbit/s, spread across six fiber pairs. This is not among the highest capacities in its region, but SJC stands out for its earthquake-resistant routing and direct connectivity to the Unity cable for low US latency.
SJC entered service on June 27, 2013, and was jointly built by TE SubCom and NEC. It is operated by a consortium of ten telecommunications and technology companies, including Google, KDDI, China Mobile, China Telecom and SingTel.
This mainly depends on the landing points and capacity you need. SJC is a good fit for a proven, earthquake-resistant route with direct US connectivity via Unity, APG offers broader North Asia-Southeast Asia coverage with higher capacity, and SJC2 currently provides the highest capacity of the three systems. Combining systems is often the better choice to ensure genuine redundancy. SAVECALL advises on the right combination on a vendor-neutral basis.
Genuine redundancy only exists when the chosen cables use different landing points and physically separate routes, for example combining SJC with APG or SJC2. Since all three systems connect some of the same countries, companies should carefully examine the actual physical routing and landing stations used. SAVECALL plans these concepts independently of any single cable operator, with a focus on actual failover reliability.
Access to capacity on SJC runs through direct wholesale partnerships with the consortium partners, as well as IRU or leased capacity agreements. SAVECALL negotiates these structures directly with the relevant carriers, without detours via reseller chains. Book a free consultation to discuss the right capacity solution for your business.
