4Gbps 3R Multi-rate Transponder - Dual Channel

The FRM220-4G-3R is a dual channel, multi-rate (up to 4.25Gbps), 3R optical regeneration device. The "3R" consists of Re-amplification, Re-shaping and Re-timing. 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. When the FRM220-4G-3R card is placed in the FRM220 rack with SNMP management, the user can view the converter card's status, type, version, fibre link status and alarms. The card can be configured to enable or disable ports, reset ports, provide diagnostic loopbacks, and set the desired data rate.

The four fibre ports can provide either dual transponder or 1+1 optical protection functions. Automatic optical line Protection Switching is supported for the aggregate fibre port.

Multi-Protocol support

This card is specifically designed for popular protocols that support speed up to 4.25Gbps. They include SONET, SDH, Ethernet, OBSAI, CPRI, and Fibre Channel, SDI.

Management options

The FRM220-4G-3R provides three methods of management.

1.    Stand-alone - simple DIP settings
2.    Stand-alone - with serial console, menu driven, overrides DIP    settings
3.    Rack - When placed in NMC managed rack, all other settings are overridden by the NMC management.

The FRM220-4G-3R has an on-board 8 pole DIP Switch which can be used to configure the device for stand-alone operation when non-managed. When placed in a stand-alone chassis with DB9 console port, these devices also support a text based serial terminal with an easy to use menu system for configuration. When used in a managed chassis, the card is configured and monitored through the chassis NMC(network management controller) via console, Telnet, Web HTTP or SNMP.
