Optical Protection Switch

1+1 Optical Protection Switch - LOLP1P1

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.

  • 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
  • Simple, stable and yet highly reliable circuit design.
  • Independent management modules
  • AC/DC dual power supply
