The cable’s Japanese landing stations will be in the prefectures of Mie and Ibaraki, both on the main island of Honshu. Canadian landings will be at Port Alberni on Vancouver Island, and in the city of Vancouver (which is not on Vancouver Island).
Google predicted the cable should be in business in 2023, and will enable low-latency access to Search, Gmail and YouTube, Google Cloud, and other Google services, but also increasing capacity to the region for a variety of network operators in both Japan and Canada.
The width of a garden hose, the Topaz cable will house 16 fiber pairs, for a total capacity of 240 Terabits per second (not to be confused with TSPs). It includes support for Wavelength Selective Switch (WSS), an efficient and software-defined way to carve up the spectrum on an optical fiber pair for flexibility in routing and advanced resilience. They’re proud to bring WSS to Topaz and to see the technology is being implemented widely across the submarine cable industry.
The cable also employs Wavelength Selective Switch (WSS) – tech that Meta plans to use on the Apricot cable linking several south-east Asian nations.
