The iConverter GX/T media converters are members of the modular iConverter product family. The GX/T provides 10/100/1000 UTP copper to GigE fiber conversion and can be used in a managed or unmanaged fashion.

The GX/T is ideal in network core or Central Office (CO) applications when conversion is required from a 10/100/1000 core switch to GigE fiber, and in edge applications when the GigE fiber is converted back into 10/100/1000 copper and delivered to a departmental or Customer Premise (CPE) switch.

The fiber port of the GX/T is available with multimode, single-mode and single-fiber and supports SC, MT-RJ and LC connectors.

The UTP port supports 10/100/1000 and Half/Full-Duplex auto-negotiation with both hardware and software manual override controls.

The GX/T features two 10/100 Ethernet backplane ports to provide connectivity to adjacent modules for network expansion and for in-band connectivity to an iConverter Network Management Module (NMM2).

Advanced features include VLAN, which allows network managers control the traffic flow between the UTP, fiber and backplane ports to enhance security, and Port Access Control, which provides the ability to enable or disable individual ports to control delivery of services to customers. The GX/T also supports port level MIB statistics reporting a real-time packet statistics to provide performance and operational monitoring.

The GX/T features user-selectable Link Propagate, Link Segment, Remote Fault Detection and Symmetrical Fault Detection modes to facilitate quick fault detection, isolation and reporting.

iConverter GX/T modules are hot-swappable and can be mounted in a 19-Module (2U high) or 5-Module (1U high) rack-mountable chassis (19-inch or 23-inch) with any combination of redundant AC, 24VDC or 48VDC power supplies. They can also be mounted in a 2-Module AC or 18 to 60VDC powered chassis, or in a 1-Module AC/DC powered chassis.

Management is accomplished by using a Network Management Module (NMM2) or a media converter with integrated management (such as an iConverter 10/100M2) that provides monitoring, remote configuration and trap notification. The management module can be accessed via SNMP, Telnet, and via a serial port. The SNMP-based management is accomplished via Omnitron's intuitive, graphic-oriented NetOutlook management software or third party SNMP management software. Management via the Telnet and the serial interfaces have an easy-to-use, menu-driven interface.

Some of the real-time GX/T parameters that can be monitored include duplex mode (Half, Full), link and data receive status. Other parameters include module type and model, hardware and software revisions, serial numbers and a user-defined identifier. The port MIB statistics include transmit and receive packet counts, error counts, etc.

The network manager can set programmable-only (Soft) parameters and override the module's physical switch (Hard) settings remotely via the management software. The Soft parameters include VLAN map setting and Port Access Control setting. Some of the Hard switch-selectable parameters include fiber or UTP auto-negotiation, UTP Half/Full-Duplex, Link modes and Port Access Control.

The iConverter GX/T supports SNMP trap notification for the monitoring and notification of different network events. Specific GX/T events that generate traps include module insertion and removal, and port link-up and link-down. Trap monitoring of specific events can be selectively enabled or disabled by the network management software.

For wide temperature (-40 to 60º C), add a "W" to the end of the model number.
Consult factory for extended temperature (-40 to +75º C) models.
When using single-fiber (SF) media converter models, the Tx wavelength on one end has to match the Rx wavelength on the other.
*A minimum of 3dB of attenuation is required for these models.
1 62.5/125μm, 100/140μm multimode fiber up to 220m. 50/125μm multimode fiber up to 550m. Refer to the fiber cable manufacturer for multimode distance specifications.
