Vancouver-Bowen Island-Vancouver Island: A Regional Connectivity Cable
The Vancouver-Bowen Island-Vancouver Island submarine cable is a 75-kilometer fiber optic system connecting key locations in British Columbia, Canada:
Cape Roger Curtis on Bowen Island,
French Creek on Vancouver Island,
Horseshoe Bay on the mainland, and
Snug Cove on Bowen Island. Owned by Rogers Communications, the cable has been listed as in service since 2019, according to GeoCables records. Its primary function is to support regional telecommunications, including internet and data services, across these coastal communities.
What makes this cable particularly interesting is the lack of publicly disclosed technical details, such as its design capacity, fiber pair count, and supplier information. While it is common for operators to keep certain specifications private, this opacity limits a full understanding of the cable's technological capabilities and its role in the broader network infrastructure of British Columbia. Additionally, latency measurements from remote probes highlight the complexity of interpreting real-world performance versus theoretical calculations.

Route
The cable connects four landing points along the southern coast of British Columbia:
- **Cape Roger Curtis**: Located on Bowen Island, this landing point serves as a critical node for connecting the island to the mainland and Vancouver Island.
- **French Creek**: Situated on Vancouver Island, French Creek provides connectivity to the island's population centers and serves as a gateway to regional networks.
- **Horseshoe Bay**: A mainland landing point near Vancouver, Horseshoe Bay is a key location for integrating the cable into broader terrestrial networks.
- **Snug Cove**: Another Bowen Island landing point, Snug Cove complements Cape Roger Curtis in ensuring reliable connectivity for the island.
The cable's route spans the Strait of Georgia, a busy maritime corridor with significant ecological and logistical considerations for submarine cable installation and maintenance.
Why it was built and what it carries
The Vancouver-Bowen Island-Vancouver Island cable was built to enhance regional connectivity between the mainland, Bowen Island, and Vancouver Island. These areas rely on reliable telecommunications infrastructure for internet, voice, and data services, particularly given their geographic separation by water. While specific traffic types are not disclosed, the cable likely supports residential, commercial, and potentially enterprise-level data demands in this part of British Columbia.
History: what can be established
GeoCables records indicate the cable was ready for service in 2019, and no conflicting dates have been identified in publicly available industry sources. Rogers Communications is listed as the sole owner, and the cable remains in active service as of the latest updates. However, details regarding its construction timeline, supplier, and installation methods are not publicly documented.
Capacity and technology
The design capacity, fiber pair count, and specific technology employed in the Vancouver-Bowen Island-Vancouver Island cable are not disclosed in public sources. Without operator documentation, it is impossible to state these parameters definitively. Industry-standard practices for regional submarine cables typically involve high-capacity fiber optics with multiple fiber pairs, but attributing specifics to this cable would be speculative.
Latency: the physics
The computed one-way light propagation latency over the 75-kilometer wet segment is approximately 0.4 milliseconds, with a theoretical round-trip time (RTT) floor of 0.7 milliseconds. However, real-world latency is higher due to land tails, terminal equipment, and routing. Live measurements from remote probes show significantly higher RTT values, such as 100.3 milliseconds from Saint Petersburg to Horseshoe Bay and 202.8 milliseconds from Singapore to Horseshoe Bay. These figures reflect the full internet path-including terrestrial segments and network routing-not the cable itself.
Redundancy: what happens if it breaks
If the Vancouver-Bowen Island-Vancouver Island cable were to experience a fault, redundancy would depend on alternative connectivity options within the region. Other submarine cables or terrestrial networks may provide backup, but specific redundancy arrangements for this cable are not disclosed. Repairing submarine cables typically involves deploying specialized vessels to locate, retrieve, and repair the damaged segment, a process that can be logistically complex in the Strait of Georgia's busy maritime environment.
Bottom line
- The Vancouver-Bowen Island-Vancouver Island cable spans 75 km and connects four landing points in British Columbia.
- Owned by Rogers Communications, it has been listed as in service since 2019.
- Technical details such as design capacity, fiber pairs, and supplier are not publicly disclosed.
- Computed latency over the wet segment is ≈ 0.4 ms one-way; real-world RTT measurements are significantly higher.
- Redundancy options and repair logistics are not documented but would follow standard industry practices.
