Crosslake Fibre Completes Installation of Submarine Fibre Optic Cable

On August 24, PortsToronto was pleased to host Crosslake Fibre as they celebrated the completion of a submarine fibre optic cable bridging Lake Ontario between Toronto and Buffalo, New York. While submarine cables have existed for hundreds of years, and dozens run across our oceans, Crosslake Fibre’s project is a first in the Great Lakes and provides critical telecommunications infrastructure for our region.

The C.S. IT Intrepid, an ocean-going cable-laying ship, installed the 60km, 96 fibre-pair cable using a four-metre high tethered plough to bury the cable into the lakebed at an average depth of one metre and a maximum water depth of 142 metres at its deepest point.
