The City-to-City (C2C) Cable System is a 17,000 km private Intra-Asia submarine cable system. The C2C cable system is designed with a dual-ring ("8") configuration, i.e., the northern ring linking Japan, Korea, China, Taiwan, Hong Kong and the Philippines, and the southern ring linking Hong Kong, the Philippines and Singapore. The C2C cables consist of 8 fiber pairs, initially designed with 96x10Gbps DWDM over each fiber pair.

Pacnet took over the control of C2C in 2007, and merged the C2C network with the EAC network to form a combined EAC-C2C network,the combined EAC-C2C has a design capacity of 17.92 Tbps to 30.72 Tbps.
