The ION S6010 is a stand-alone managed media converter that offers a solution for extending DS1 - T1/E1 or PRI connections over fiber optic cabling. It provides fiber extension though a twisted pair RJ-48 port and a fiber port. These DS1 - T1/E1 converters must be used in pairs one on each end of the fiber link. Management of the stand-alone converter is supported in-band over the fiber when the remote S6010 is linked to a C6010 card installed in a managed ION Chassis. These DS1 - T1/E1 converters are available with fixed fiber connectors or an open SFP slot with support for various fiber types distances and wavelengths to provide maximum flexibility for any network topology. CWDM SFPs can also be used to further increase the bandwidth capacity of the fiber infrastructure.
