4G 2R Multi-rate Transponder with Optical Line Protection

4G Transponder Card: FRM220-4G-3S

The FRM220-4G-3S is a 2R 4G optical regeneration device, which consists of Re-amplification and Re-shaping. The transponder card converts a data signal to the correct wavelength for transmission on a specific channel by supporting SFP optics on both line side and client side interfaces. 1+1 Automatic optical line Protection Switching is supported for the aggregate fiber ports. When the FRM220-4G-3S card is placed in the FRM220 rack with SNMP management, the management can view the converter card's status, type, version, fiber link status and alarms. The card can be configured to enable or disable the port, reset the port and perform diagnostic loop backs.

  • Multi-rate supports 28Mbps to 4.25Gbps
  • Network management via Web, Telnet, SNMP in central FRM220 chassis
  • Local configuration via DB9 console port (when placed in CH01M or CH02M)
  • Digital diagnostic monitoring of SFP module
  • Perform optical repeater function (Re-amplification, Re-shaping)
  • Facility loopback on both Client / Line sides
  • 1+1 optic fiber protection, switching time < 50ms
  • Link Fault Pass-Through (LFPT)
  • Auto Laser Shutdown (ALS)
