Grouped Dedicated Line Carrier Network Solution
Overview
As With the rapid development of 4G and 5G networks, new services featuring high bandwidth and ultra-high reliability are continuously emerging. Previously, dedicated line bandwidth and latency simply couldn’t keep up with network growth, leading to a steady increase in demand from customers requiring both large bandwidth and low latency. Meanwhile, traditional SDH network resources are being rapidly depleted as the industry shifts toward packet-based networks. In response, Shanshui Optoelectronics has introduced its IPRAN U equipment-based packetized dedicated-line transport solution, offering exceptional features such as massive bandwidth, ultra-low latency, robust multi-service support, and unparalleled security—making it ideally suited for a wide range of applications. Government and Enterprise Business Onboarding , typical scenarios such as cloud private line access.
