A little HistoryThe First cable to Asia, from the Red Sea to India was laid in 1859-1860 but never worked over its full length.
First trans-Pacific telegraph cable was completed in 1902 between the United States and New Zealand.
First Amplified telephone cable, TAT-1 was completed 1955.
After two decades, the first fiber optic cable across the Pacific became operational (TPC-3, in 1988) Soon afterwards it was connected to the Hawaii-4 & Guam-Philippines-Taiwan (GPT) cables, thus completing the 1st digital links across the Pacific.

The Tug of War of the Cost of Cable
For suppliers: The first system to connect bandwidth-starved points may capture sales at a much higher price than when the rest of the bandwidth barons (private or consortium) join in.
For Buyers: The opposite strategy holds true: If you don’t like bandwidth prices now, wait a bit. They will likely change soon enough.
