Fiber based access networks can deliver performance that can support the increasing demands for high speed connections. One of the new technologies that have emerged in recent years is Passive Optical Networks (PON). To satisfy future bandwidth demands, existing fiber-to-the-home (FTTH) access networks must be upgraded. Since the lifetime of a passive optical network (PON) is expected to be greater than 25 years, replacing the existing PON infrastructure is not desirable when upgrading the network throughput. Fiber based access systems can demand of execution that can high speed net- work. One of the new innovations that have risen as of late is Passive Optical Net- works (PON). Fiber-to-the-home (FTTH) is encountering awesome open acknowl- edgment all through the world. For investigate the Fiber-to-the-Home architecture are main work with any users can drop or add in optical fiber communication for long distance. In continues type laser to external modulated source through each user allocated separate wavelength then no inter symbol interference (ISI) and for same wavelength we can nearest distance then drop the same wavelength and same wave allocate for in-line next user.
