STN6200B-SR2

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

Overview:

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


The switching control and management control of SR2 are independent with each other in design. Switching function is priority guaranteed, the switching delay is less than 15ms. SR2 provides AC and DC redundant power supply. Industrial design, it can work stably in harsh environment. SR2 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 supports remote upgrade, current alarm and route status can be displayed on LED, equipment status is clear to see.
