Stand-alone DS1 – T1/E1/J1 Network Interface Device
4 x DS1 – T1/E1/J1 over Fiber


The ION S6110 is a 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 over fiber. The S6110 includes (4) RJ-48 ports and (1) fiber port. The device offers support for a variety of fiber 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.

The S6110 converter must be used in pairs. Management of the stand-alone converter is supported, in-band, over the fiber, when the remote S6110 is linked to a C6110 card installed in a managed ION chassis.
