16G 3R Multi-rate Transponder - Dual Channel


  • Dual channel transponder
  • Suitable as a repeater for transmission over extended distances.
  • Low power
  • Multi-rate support 1Gbps ~ 16Gbps
  • Protocol Transparent 3R fibre Media Transponder / Repeater
  • Managed or unmanaged
  • 1+1 Optical Line Protection, switching time <50ms
  • 2 channels with different bit rates


The FRM220-16G-3R has 4 SFP+ slots that can be configured as a dual channel 16G 3R multi-rate transponder or in a 1-to-2 port protection mode. The device provides a flexible transmission of various protocols, such as 1G/10G Ethernet, SDH STM16/STM64, OTU1/ OTU1e/OTU2/OTU2e, Fibre Channel 1/2/4/8/10/16, ODU, OBSAI, CPRI, etc. Using SFP+ ports with dedicated CWDM or DWDM wavelengths, the 16G transponder supports multi-rate functionality with optical data rates from 1Gbps up to 14Gbps. With its functionality the FRM220-16G-3R transponder is also suitable as a repeater for transmission over extended distances. In addition, the use of state of the art components greatly reduces the power requirements and heat dissipation factors over our previous transponders.
