Existing customers who sign up for the service won't need to change cables. The service will allow users to download high volumes of content using multiple devices.
SK Broadband, a wholly owned subsidiary of the country's largest wireless carrier, SK Telecom, is using what's known as a Gigabit Passive Optical Network (GPON) to get these blazing speeds. GPON technology uses what's known as a "point-to-multipoint architecture," in which a single optical fiber is used with multiple unpowered fiber splitters.
SK Broadband says it developed its GPON technology as an alternative to ethernet cables, and according to the Korean Herald is saying that customers will not need any additional cables. With one cable, SK GPON can hit up to 52.5Gbps.
SK Broadband current coverage is 40 percent but it will invest 1 trillion won going forward to expand this to 80 percent by 2020.
