1+1 Optical Protection Switch card

LOLP1P1 optical line protection service board is with features of transparent and independent transmission signals, high safety and reliability as well as fast fault recovery, which can help users to build a non-blocking, flexible and reliable, as well as anti-disaster optical communication network. it is designed with separate switch control and management control. It gives priority to ensuring the link switching, and the switching latency is less than 15ms. It provides AC/DC dual power supply and adopts industrial grade design, which ensures stable operation under harsh environments. It is designed with powerful graphical network management system, which supports three management modes–local Console, EMS and button setting. Moreover, remote upgrade of devices can be realized, which is easy for future unified management and maintenance.

 

  • Provide 1+1 protection mode
  • Lock when there is no light
  • Support a variety of management modes: Console, EMS system and button setting
  • Support TFTP remtoe upgrade
  • The switching module adopts simple and stable circuit design, which is with high reliability. Moreover, the management modules are independent from each other and do not affect each other
  • AC/DC dual power supply and wide voltage range adaptation which is safer and more stable
