FRM220 series platform is based on in-band and 802.3ah management, providing web-based, SNMP, telnet and console access on all media converter models hosted. Moreover, the special OAM series of the FRM220 converter family does support 803.2ah management features, making them a perfect choice for service providers and telcos. The 10G transponder cards as well as the mux/demux cards for CWDM and DWDM wavelengths are adding a new dimension to the series. There are 3 different 10G, SONET OC-192/ STM-64 transponder cards, accepting a wide selection of XFP and SFP+ 10G rate optical transceivers. 10G converters/transponders are used for Ethernet 10G, SONET OC192, SDH STM-64 or Fibre Channel 10G interfaces to migrate between different fiber configurations. The all optic converters are very useful in CWDM/DWDM interface aggregation applications.
