Leveraging GPON for Mobile Backhaul Networks

As mobile operators deploy 3G networks, subscribers are increasingly accessing bandwidth hungry services such as Internet access and streaming video with their Smartphone. However, these services are straining the traditional voice-optimized TDM mobile backhaul network, which does not cost-effectively scale to handle exponentially increasing data traffic. In response, converged packet-based mobile backhaul solutions are being developed to help network operators meet the cost challenges of supporting 3G services while effectively preparing for future Long Term Evolution (LTE) networks. These solutions leverage the GPON triple play network, which is uniquely positioned for rapid and cost-effective relief of the mobile backhaul bandwidth problem. With GPON, expensive leased lines, whose costs scale linearly with bandwidth, can be capped and ultimately retired.
