Port Alberni, BC, Canada

Port Alberni, BC, Canada: Submarine Cable Landing Point

Port Alberni is a city situated on Vancouver Island in the province of British Columbia, Canada. The city lies within the Alberni Valley at the head of the Alberni Inlet, Vancouver Island's longest inlet. As a landing point for submarine cable infrastructure, Port Alberni connects Canada to a trans-Pacific corridor that reaches Japan and Taiwan, placing this inland-inlet community within the broader network of international submarine communications.

One submarine cable currently lands at Port Alberni: the Topaz cable, which entered service in 2023. This single cable establishes Port Alberni as a trans-Pacific landing point, linking Canada directly with Japan and Taiwan across the Pacific Ocean. That intercontinental reach makes Port Alberni part of one of the most significant cable corridors in terms of geographic span.

Cables Landing at Port Alberni, BC, Canada

Topaz reached ready-for-service status in 2023. The cable connects landing points in Canada, Japan, and Taiwan, forming a trans-Pacific route. Port Alberni serves as the Canadian terminus on this system, completing a link that spans thousands of kilometres across the Pacific Ocean to endpoints in East Asia. No additional length or capacity specifications are published for this cable at the time of writing.

Regional Context

Within Canada's submarine cable landscape, Port Alberni is one of 155 landing points spread across the country, which together host a total of 21 submarine cables. Port Alberni hosts a single cable, placing it alongside Addenbroke Island, BC, as one of the single-cable landing points on Canada's Pacific coast, while nearby Vancouver and Prince Rupert each host two cables. On the Atlantic side, Halifax and the Quebec Arctic communities of Kangiqsujuaq and Puvirnituq also each host two cables, reflecting a broader national pattern in which most Canadian landing points serve a focused, rather than aggregated, cable function.

Network Role

Port Alberni functions as a single-cable terminus rather than a multi-cable hub. Its role within the submarine cable graph is defined entirely by the Topaz cable and the trans-Pacific corridor that cable enables between Canada and East Asia. The landing at Port Alberni on Vancouver Island's western-facing inlet positions the city as a point of entry for Pacific data flows arriving on Canadian soil before onward terrestrial distribution.

Within the regional submarine cable graph, Port Alberni's presence as a trans-Pacific landing point on Vancouver Island adds geographic diversity to British Columbia's cable infrastructure, complementing the other cable-landing communities along Canada's Pacific coast.
