Fiber-to-the-X (FTTX, X is home/curb/building) is used for broadband access. There are two services: cable TV [1] and plain old telephone service (POTS) using FTTX equipment [2]. “Fiber-to-the-Home” (FTTH) is a communication architecture in which a communication path is established from optical fiber cables to an optical line terminal (OLT) unit located in telecommunications operator’s switching setup connecting to optical network terminal (ONT). The above two services were provided by two separate architectures. The arrival of high-bandwidth WWW using FTTX has made easy home data communication services along with TV and telephone [3]. The diverse type of traffic flowing through the Internet demands constant bandwidth for quality-of-service (QoS) of transmission. The transmission system is made to give a best-effort service by statistical multiplexing. The data rates range from 100 Mbit/s to 10 Gbit/s in LANs, but MANs and WANs need broadband access having a range in 100 Kbit/s to a few Mbit/s. It is evident from literature that no other technologies other than optical fiber can provide very high bandwidth and optical fiber becomes the ideal medium for high-bandwidth access to integrated services in the networks. In this direction, the FTTX technology such as FTTH has been focused for accessing high-bandwidth services.
