Optical Protection Switch - Singlemode

CT-FRM220-OPS51/2

Image
  • Provides fibre path redundancy
  • In case of a fibre failure in the active path, traffic will be switched over to the protected path
  • Monitoring and management is available via HTTP/SNMP when placed alongside FRM220-NMC
  • Protection transition < 50 ms (FRM220-OPS51)
  • Protection transition < 20 ms (FRM220-OPS52)
  • Works across entire C/DWDM spectrum
  • Traffic is switched in one of three modes : revertive, non-revertive, manual (OPS52) or non-revertive, manual (OPS51)
  • Programmable RX threshold setting for fail-over
  • Optical Interface Type : LC connectors
  • Working and protected lines are physically separated fibres

Overview

The FRM220-OPS Series 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, including CWDM & DWDM links. The OPS52 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 FRM220 racks with SNMP management. The management can view the converter card's status, type, version, fibre link status and alarms. The card can be configured to enable or disable the port, reset the port, and configure receive threshold levels for path switching.
