论文摘要
移动用户的数量正在迅速增加，3GPP启动了新技术4G长期演化（LTE）。 LTE是一种能够解决网络容量和质量问题的方法，例如Sleman等需求很高。 LTE网络的质量由骨干网和分销网络支持。本文将光纤网络的设计描述为Sleman中的LTE骨干网络。骨干网络需要带环拓扑和WDM-STM64技术沿85公里的G-652光电缆。分销网络使用GPON技术和沿61.35公里的G984光电缆的类型。通过计算，在OptiSystem模拟中端点接收到的最小功率为-25 dBm和-26 dBM。该值是可以接受的，因为它高于接收到的功率的最小值（接收器灵敏度）-28 dBM，它指的是G.984.2的标准参数。上升时间的平均值为69 ps，此值仍低于上升时间70 ps的最大允许值。骨干链路的平均BER为5x10-4。
The number of mobile users is increasing rapidly, 3GPP initiated a new technology 4G Long Term Evolution (LTE). LTE is an enabling technology as a solution to the problem of network capacity and quality in areas that have a high demand like Sleman. The quality of LTE networks are supported by backbone and distribution network. This paper describes the designing of fiber optic network as the LTE backbone network in Sleman. The backbone network requires G-652 optical cable along 85 km with a ring topology and WDM-STM64 technology. The distribution network uses GPON technology and the type of G984 optical cable along 61.35 km. The minimum of power received at the end-point in the optisystem simulation is -25 dBm and -26 dBm through the calculation. This value is acceptable, since it is above the minimum of power received (Receiver Sensitivity) -28 dBm which refers to the standard parameters of G.984.2. The average value of rise time is 69 ps, this value is still below the maximum allowable value of rise time 70 ps. Average BER of backbone link is 5x10-4.
