| Block Diagram of Two fiber UPSR The full form of UPSR is Two Fiber Unidirectional Path Switched Ring (UPSR). Normally the working of traffic travels clockwise around the ring on primary path. Connection from Node 1 to Node 3 links 1 & 2. Traffic clockwise path is the protection path, if the link or Node fails, protection path (Link 5 to 8) is indicated by dashed lines. To achieve protection, signals from a transmitting Node is a dual fed into both primary and protection fiber. |
Hello friends my name is Rajakumar Dayashankar Gupta . Here I am started to write blog on name scientechplus . I am started to writing this blog post on science , technology and engineering since 2020 . I completing my ssc , than after I go for stream in science field , than after completing my 12th science than later I realize my self , I am interested in electronics fields , so I start learning in diploma electronics engineering . My journey is quite interesting to choosing right decision of my aim . And I want to explain the concept in simple and precise way . I every time want to learn something new , it means that something new from open minded from our environment . To learn something new from our expectation . It quite special and very interested to hear that , when we imagine or think we go to learn something very uniqueness our eyes fill with glow , that moment is such a very great pleasurable moment we feel isn't it ? .
