Abstract:
1. A method for establishing an underwater optical communication link between a first cabled observatory and a second cabled observatory, the method comprising: disposing a first optical modem within an optical range of the first cabled observatory, wherein the first optical modem is mechanically coupled to a second optical modem by a tether; disposing the second optical modem within an optical range of the second cabled observatory, wherein the second cabled observatory has a location different from that of the first cabled observatory; establishing an optical connection between the first cabled observatory and the second cabled observatory, through the first optical modem, the tether and the second optical modem, wherein the first optical modem and second optical modem communicate by diffusing electromagnetic radiation of wavelength in the optical spectrum between 300 nm to 800 nm; disposing a third optical modem within an optical range of the second cabled observatory; disposing a fourth optical modem within an optical range of a third cabled observatory, wherein the third cabled observatory has a location different from the first and second cabled observatories.
