DS3 – T3/E3 Coax over Fibre

TN-S6210 E3 Modem

  • Managed stand-alone DS1 - T1/E1/J1 media converter mux that provides a solution for those users that need to extend multiple DS1 - T1/E1/J1 connections, along with a 10/100 Ethernet connection, all over fibre.
  • Includes (4) RJ-48 ports, (1) 10/100 Ethernet port, and (1) fibre port.
  • Device is available in versions that support fixed fibre connectors as well as SFP fibre modules offering support for a variety of fibre types, distances, and wavelengths to provide maximum flexibility across a variety of network topologies.
  • CWDM SFPs can also be utilized to further increase the bandwidth capacity of the fiber infrastructure.
  • Converter must be used in pairs.
  • Management of the standalone converter is supported, in-band, over the fibre, when the remote S6120 is linked to a C6120 card installed in a managed ION chassis.
