SK Broadband has announced the successful implementation of DOCSIS 3.1 broadband technology to enhance its cable infrastructure. The next-generation HFC standard improves frequency efficiency and increases cable network capacity to support demand for more internet video and the growth of connected devices. SK Broadband rolled out a DOCSIS 3.1 pilot service in the Anyang area in Gyeonggi Province and the Gwangju area in Jeollanam Province in November 2017. Using the Cisco cBR-8 converged broadband router, SK Broadband hit speeds of 4Gbps downstream and 1Gbps upstream. The company expects to roll out a large-scale service deployment in the second half of 2018.
SK Broadband plans to further expand the bandwidth of its HFC cable network to 10Gbps downstream and 5Gbps upstream by introducing more DOCSIS technology in the future.
