Application Scenarios
In Italy, ISP Mynet adopted Huawei GPON solutions including the GPHF board to participate in the EU’s €610 million "Voucher 2.0 Policy" . It enabled Mynet to upgrade 300Mbps enterprise networks to 2.5Gbps, supporting remote order management and cloud access for SMEs. The board’s stability and easy maintenance helped Mynet efficiently serve businesses nationwide, meeting surging demand for high-speed broadband and multi-service access.
