C6210 Series - DS3 – T3/E3 Coax to Fibre Network Interface Device

DS3 – T3 E3 Coax to Fibre Network Interface Device

The C6210 DS3 – T3/E3 copper to fibre network interface device (NID) provides a solution for those users that need to extend DS3 connections over fibre. The DS3 – T3/E3s supports Small Form Pluggable (SFP) transceivers to support a variety of fibre types, distances and wavelengths to provide maximum flexibility across a variety of network topologies. The use of Coarse Wave Division Multiplexing (CWDM) SFPs can be utilized to further increase the bandwidth capacity of the fibre infrastructure. The DS3 – T3/E3 NID must be used in pairs. A typical installation will include a chassis card installed in the ION Platform locally and a stand-alone device installed at the remote location.
