FAFS-GDSES2R4-40C,10/100/1000M Dual Fiber Ethernet Switch For Ring Network With Four RJ45 Ports

Self recovery optical fiber Ethernet switch (fiber media converter) is a switch that can support the group ring network protocol. It is with ring network redundant backup line. If a link network is formed, the network will automatically recover if a link fails to enable the standby line.

The so-called self healing ring (SHR), generally refers to the use of ADM to form a circular network to achieve self-healing. According to the classification of optical fiber number of self-healing ring, there are two fiber ring and four fiber ring; Fiberall’s ring type optical fiber media converter is with at least 2 optical ports, single or double fiber, there are two kinds of self-healing methods:

Two fibers unidirectional self healing ring: The two fibers unidirectional channel protection ring is realized by two optical fibers, one is used to transmit the service signal, and the other is used for protection. The basic principle of the system is 1+1 protection (first end bridging and terminal switching), that is, using 1 fiber and 2 optical fiber to carry business signals at the same time and transmit them in two directions respectively, but the receiver only chooses one of them. From the perspective of realization function, this protection belongs to the subnet connection protection type. From the capacity perspective, the traffic capacity of the ring is equal to the sum of all traffic entering the ring.

Two fibers two channels bi-directional protection ring: also use 2 fibers, and can be divided into 1+1 and 1:1 in two ways, 1+1 method and unidirectional path protection ring is basically the same (transmit at the same time but receive priority), just return the signal in the opposite direction ( bi-directional). Its main advantage is to use equipment without protection ring or reuse channel function of same ADM equipment used in linear situation, thus increasing the total business volume of transplanting. Two fibers bi-directional protection can also adopt the 1:1 mode, that is, the extra traffic can be transferred in the protection channel, only when the fault occurs, it will turn from the working channel to the protection channel.

Main Characteristics Of Self Recovery Fiber Switch
