The iConverter T3/E3 is a T3 (44.736Mbps) or E3 (34.368Mbps) coax to fiber converter, and is available as a compact unmanaged standalone unit or a managed chassis plug-in module. The iConverter T3/E3 can be used to connect to devices such as PBXs, multiplexers, routers and video servers via fiber. The iConverter T3/E3 media converters operate in pairs, extending distances over fiber, which improves noise immunity, quality of service, intrusion protection and network security. The T3/E3 supports both standard and CWDM Small Form Pluggable (SFP) transceivers, enabling adaptability to different fiber types, distances and wavelengths, providing maximum flexibility across a variety of network architectures and topologies. The T3/E3 also supports multimode and single-mode dual fiber with ST, SC and LC connectors; and single-mode single-fiber with SC connectors. Individual coax and fiber port access can be controlled, providing the network administrator with an easy mechanism for controlling usage and access to the network when installed in a chassis with network management. The T3/E3 features extensive local and remote loopback user-selectable diagnostic modes. Local loopback facilitates individual coax or fiber loopback operations. Remote loopback facilitates setting a remote T3/E3 converter to loopback mode, in order to test the integrity of the fiber and the remote converter, eliminating the cost of external hardware or support personnel at each end of the link. Additional diagnostic features include forcing of all 1s data patterns, Alarm Indication Signal (AIS), to the coax or fiber interfaces and generating and monitoring a Pseudo Random Bit Sequence (PRBS) per ITU O.151 specification. These diagnostic features combined with the informative and easyto-read LED display facilitate quick installation, fault detection, isolation and correction. The hot-swappable plug-in module can be mounted in a 19-Module (2U high) or 5-Module (1U high) rack-mountable chassis. It can also be mounted in a 2-Module or 1-Module powered chassis. The T3/E3 standalone unit is available as a wall-mount unit. The wall-mount models are DC powered and are available with an external AC to DC power adapter or a terminal connector for DC power.
