Subsea Cables & Internet Infrastructure

Lisbon/Lagos is 77 ms RTD. My best estimate to date.  Shortest latency of all subsea cables between Lisbon and South Africa: 130 ms RTD. Also the most reliable and least expensive. Equiano lands not just in Portugal, Nigeria, and South Africa, but also Togo and Namibia. Any sufficiently large ISP in those four African countries should be on the system. Feel free to ping me for a quote. ☺ Deepest buried African subsea cable: averages 2 meters.

The wholesale telecom community eagerly anticipates the lighting of the ADC system. This 8 fibre pair cable has an intitial design capacity of 180 Tbps. It will serve China, Japan, Singapore, Philippines, Thailand, and Vietnam. NEC is building the cable. Consortium members include China Unicom, China Telecom, Singtel, Softbank, Tata, and one of the two Vietnam operator incumbents.  My sources tell me the current RFS estimate is January, 2025.  Good Singapore/Tokyo pricing available. Figure as low as $15K per monthon long term contracts.  SJC and SJC2 are relatively good complements as they do not share cable landing stations with ADC.  HK-SG 35.5 ms RTD. SG-TOKYO 66.5 ms RTD.  TOKYO-HK 44.5 ms RTD.  Singapore Landing Station: Tuas. Tokyo Landing Station: Maruyama.
