FRM220-OPS51 & OPS52 Fibre Optical Protection Switch

1+1 Fibre Optical Protection Switch

The FRM220-OPS Fibre Optical Protection Switches are able to provide fibre path redundancy on a channel by channel basis. These units are particularly well suited for protection in any type of fibre data transmission. This solution includes monitoring capabilities for both the working and protected path fibres. In case of a fibre cut in the active path, traffic will be switched over to the protected path in less than 50ms (FRM220-OPS51) or 20ms (FRM220-OPS52). Monitoring is available through SNMP Management when both cards are placed in an FRM220 rack with SNMP management. The management can view the converter card's status, type, version, fibre link status and alarms. The selected card can be configured to enable or disable the port, reset the port, and configure receive threshold levels for path switching.

Fibre Optical Protection Switches


  • Latch feature, if power is lost the switch remains in its current state
  • Protection transition < 50 ms (FRM220-OPS51)
  • Protection transition < 20 ms (FRM220-OPS52)
  • Works with any combination of 1 ~16 wavelengths
  • Traffic is switched in one of three modes : revertive, non-revertive, manual
  • Programmable Rx threshold setting for switch-over
  • Optical Interface Type : LC connectors
  • Working and protected lines are physically separated fibre
