The evolution of communication network comes from the need for users to stay connected anytime and anywhere. Modernization of the network continues to be done to increase bandwidth capacity in order to obtain an increase in multimedia services, especially in urban areas. Of various transmission media, optical fiber is the best choice to support reliable communication networks. One of the optical fiber communication technologies is Fiber to the Home (FTTH). This study proposes FTTH network design with Gigabit Capable Passive Optical Network (GPON) technology aimed at housing in urban areas. The design uses aerial and duct-aerial cabling systems. The design analysis is carried out based on the parameters of the link power budget, rise time, Bit Error Rate (BER), components and costs required. The value of the power budget link for the uplink and downlink are -22.792 dBm and -23.120 dBm. The rise time value for uplink and downlink are 0.256 ns and 0.258 ns, while the BER value is 14.628 x 10-12. The calculation results show that the design meets the required parameters, hence, the proposed network can be implemented. For the cost components required by the aerial system, it is 11.56% less than of the ductaerial sistem.

Even though congestion is not unusual, traffic jams still result in very high economic and social losses. Several factors cause congestion, one of which is traffic lights. Therefore, a mechanism is needed so that traffic lights can intelligently and adaptively manage signal time allocation according to traffic flow conditions. A traffic light with this type of mechanism is known as a smart traffic light. Smart traffic light cycle settings can be grouped based on the traffic density, scenarios for emergency vehicles, and the interests of pedestrians. This paper analyzes the methods and technologies used in the development of smart traffic light technology from the perspective of these three situations as well as the development of smart traffic light technology in the future.</span></span>
