In today's passive optical network, each optical network unit receives not only the data that belongs to its user but also the data of other users. This makes the network vulnerable to sniffing even though encryption has been done. To solve this problem, optical channels from an optical line terminal are switched directly to different user locations in such… CONTINUE READING
