Every relation drawn, in words4

The Convention for the Protection of Submarine Telegraph Cables · governs · The submarine fibre-optic cable
The 1884 convention obliges its parties to criminalise wilful or negligent damage to submarine cables and remains in force.
The submarine fibre-optic cable · connected_to · The cable landing station
A cable comes ashore through a buried duct or beach manhole into a landing station, where its optical channels meet the terrestrial network.
The submarine fibre-optic cable · uses · The submarine optical repeater
A transoceanic fibre attenuates its signal, so amplifier housings are spliced into the cable at intervals along the seabed.
Latency as a physical quantity · constrained_by · The submarine fibre-optic cable
Light in silica travels at about two-thirds of its vacuum speed, so intercontinental delay is set by the length of glass between the two ends.
