Networking

With the increasing demands for bandwidth, FTTH (Fiber to the Home) is considered as a next-generation technology for delivering more bandwidth, reliability, flexibility and security to end-users. PON (Passive Optical Network) is the main structure of FTTH network which can provide optical fiber bandwidth advantages at a lower cost than P2P (Point to Point) architecture affords. However, PON presents unique test challenges when installing and maintaining the FTTH network. Furthermore, optical testing is typically performed at various points in a network’s lifetime. Thus, it is very necessary to know which tests should be done and when and where to do it. In general, optical testing in FTTH can be divided into two part—installation verification testing and maintenance troubleshooting. This is a very general classification according to the state of the network. Installation verification testing occurs as the network is being constructed or after network installation is complete, b...
