Chapter 1 Introduction
1.7.14 FRM220-2.7G-2S, 2.7Gbps 3R Fiber Transponder
The FRM220-2.7G-2S is an optical 3R regeneration device, which provides re-amplification, reshaping and
retiming. 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 FRM220-2.7G-2S 3R 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
set the desired data rate.
