 Hi, I'm Andy from reedle and in this video we're going to be talking about the meaning of a fiber ring now Fiber ring is not something that you would put on the finger of the person you want to marry It refers to a fiber optic connection that you would make between different nodes or frames in your intercom system Now we use the term ring when we're talking about it because the topology we use is a ring every Point on the network is connected to all the others And then in the end we join the circle and bring it all back together now every link On the fiber ring is bidirectional which means data can flow both ways up and downstream and because of that We have some redundancy. This means that if one of the links is knocked out Someone trips over the cable pulls it out or even takes a pair of scissors to it Then the system will still continue to function because the data can pass through the other links
