The FRM220-DS3/E3 is DS3/E3 copper to fiber media converter designed for long-distance transport of DS3/ES signals. The DS3/E3 supports Small Form Pluggable (SFP) which give you the options to choose from a wide range of standard SFPs in multi-mode and single mode types as well as BiDi which allows bi-directional transmissions using only a single fiber cable. CWDM wavelength SFPs can also be used to increase the bandwidth capacity of the fiber infrastructure. With SNMP and Web-based management in FRM220 chassis, the network administrator can monitor, configure and control the activity of FRM220-E3/D3 card in the chassis locally and a stand-alone device installed at the remote location.
