STN6200B-SR2-2

The switching control and management control of SR2-2 are independent with each other. Switching function is priority guaranteed, the switching delay is less than 15ms. SR2-2 support transparent transmission, it is widely used in PDH, SDH system, C / DWDM system, power communication network, CATV optical network and other optical line protection applications.

Overview:

STN6200B-SR2-2 (short for SR2-2) is a double 1x 2 automatic optical switch. It is an automatic optical fiber (device) protection device. By monitoring the optical power status of the primary / secondary fiber (device) in real time, SR2-2 can switch the optical signal to the backup route when the optical power failure occurs in the primary route. In short, SR2-2 can avoid paralysis of the entire network communication.


The switching control and management control of SR2-2 are independent with each other. Switching function is priority guaranteed, the switching delay is less than 15ms. SR2-2 support transparent transmission, it is widely used in PDH, SDH system, C / DWDM system, power communication network, CATV optical network and other optical line protection applications.


STN6200B series products have strong graphical NMS, every device supports EMS, and keyboard setting management. Moreover, SR2-2 supports remote upgrade, current alarm and route status can be displayed on LED, equipment status is clear to see.
