The FRM220-25G-3R has 4x SFP28 slots that can be configured as a dual channel 25G 3R multi-rate transponder. The device providesa flexible transmission of various protocols, such as 1G/10G/25G Ethernet. Using SFP28 ports with dedicated CWDM or DWDMwavelengths, the 25G transponder supports multi-rate functionality with optical data rates from 1Gbps up to 25Gbps. With itsfunctionality the FRM220-25G-3R transponder is also suitable as a repeater for transmission over extended distances. In addition, theuse of state-of-the-art components greatly reduces the power requirements and heat dissipation factors over our previoustransponders.
