In this paper, we analyze the improvements that can be achieved with the introduction of low-cost technical arrangements and devices into the present Fiber-To-The-Cabinet (FTTC) networks aiming: to support statistical multiplexing of groups of copper pairs shared among subscribers at protocol layer two, and to relay signals along the main cable. With simple calculations, we prove the bit rate per user can be increased well beyond, that achieved with present Fiber-To-The-Home (FTTH) network standards. Crosstalk performance degradation with respect to ideal case are analysed in the case of VDSL2 35b and G.fast technologies. Costs of the considered solutions are compared with those of FTTH networks. We show that in a short-medium term the low cost of investments required for updating the FTTC network can extend the life of existing copper-based networks providing at the same time a significant performance improvement with respect to the current FTTC configuration. This facilitates the smooth transition to FTTH supported by the re-investing of the acquired revenues. The solution considered in this paper moves in the direction of rendering feasible the European Gigabit Society (EGS) vision, whose objectives are extremely challenging (if not unreachable within the foreseen 2025 timeframe) with an all-fiber approach. In fact, as shown in this paper the Gigabit-ready hybrid copper-fiber approach technology provides a feasible path to significantly reduce “gigabit” deployment costs so to gradually move toward all-fiber EGS vision.

在本文中，我们分析了通过将低成本技术安排和设备引入当前的光纤到机柜（FTTC）网络可以实现的改进，目的是：支持统计共享的铜对组之间的统计复用用户在协议第二层，并沿主电缆中继信号。通过简单的计算，我们证明了可以将每个用户的比特率提高到远远超过目前的光纤到户（FTTH）网络标准。对于VDSL2 35b和G.fast技术，分析了理想情况下的串扰性能下降。将考虑的解决方案的成本与FTTH网络的成本进行比较。我们显示，在短期内，更新FTTC网络所需的低成本投资可以延长现有铜基网络的寿命，同时提供相对于当前FTTC配置的显着性能改进。这将有利于向获得收入的再投资支持的向FTTH的平稳过渡。本文所考虑的解决方案朝着使欧洲千兆比特协会（EGS）愿景变为可行的方向发展，该愿景的目标是采用全光纤方法极具挑战性（如果在可预见的2025年时间内无法实现）。实际上，如本文所示，支持千兆位的混合铜纤维方法技术提供了一条可行的途径，可以显着降低“千兆”部署成本，从而逐步走向全光纤EGS愿景。
