38 Deploying and Troubleshooting Fiber Networks Understanding FTTx networks and associated optical testing The challenge of providing the increased bandwidth needed to support triple-play service delivery is on-going and can be daunting. Running optical fiber much deeper into the access network, in some cases all the way to the customer premises, is an important part of the strategy of nearly every service provider.The appeal is that a fiber optic infrastructure offers the potential for practically unlimited bandwidth and also facilitates greater control over the operation, administration, and provisioning of the access system. FTTx Architectures The general penetration of fiber into the access network is often referred to as Fiber-to-the-X (FTTx). The actual architecture can vary depending on the depth of penetration (see Figure 3.1). In an FTTx architecture, the optical line terminal (OLT) houses the laser transmitters which are dedicated to individual users in a point-topoint (P2P) network or shared in a passive optical network (PON). The optical fiber running to the users includes several components: the feeder cable which terminates at the OLT, the distribution cable which comprises the majority of the access network, and the drop cable which connects users or remote distribution points. In FTTH, the optical network terminal (ONT) receives the signal from the OLT and converts it into usable electronic signals for voice, video, and data at the customer premises. If the last mile is provided by a copper access network, the fiber is terminated at an optical network unit (ONU), often consisting of a digital subscriber line access multiplexer (DSLAM), which services the copper network and is located at a remote central office (RCO).

Therefore, for cost-saving alternatives, providers must utilize existing plants to deploy different types of fiber architectures. For new homes and new residential areas where no network is yet available, providers will deploy complete Fiber-tothe- Home (FTTH) technology. These new areas are termed “greenfield” applications. 39
