iConverter 2GXT

1519e954ae6bd629544356cae3e51766_XLiConverter 2GXT Ethernet fibre media converters are members of the modular iConverter Multi-Service Platform. The 2GXT is a dual-channel media converter and four-port switch with two 10/100/1000BASE-T RJ-45 ports and two Small Form Pluggable (SFP) ports. The dual SFP fibre ports can be configured to provide 1:1 uplink protection with less than 50ms switchover when the 2GXT is deployed as a four-port switch.

The 2GXT supports both 100BASE-X and 1000BASE-X SFPs to provide flexible connectivity to Fast Ethernet or Gigabit networks, and simplifies inventory management in large Enterprise and Telecom networks with multiple data rates. The SFPs also enable adaptability to different fibre types and distances, and support Coarse Wave Division Multiplexing (CWDM) to increase the capacity of fibre infrastructure.

The RJ-45 port supports 10/100/1000 and Half/Full-Duplex auto-negotiation with both hardware and software manual override controls.

iConverter 2GXT media converters are available as compact, unmanaged standalone units, or chassis plug-in modules that can be managed with a management module installed in the chassis. The hot-swappable plug-in module can be mounted in a 19 or 5-Module chassis with any combination of redundant AC and DC power supplies. It can also be mounted in a 2-Module AC or DC powered chassis, or in a 1-Module chassis with AC or DC power input.

The 2GXT also features two Gigabit Ethernet backplane ports for connectivity to adjacent iConverter modules in a chassis for multi-port and multi-service configurations.

Deploying 2GXT plug-in modules configured as dual-channel media converters in an iConverter chassis provides high-density fibre distribution from copper switch equipment, with twice the ports of conventional media converters. For example, installing 2GXT modules in an iConverter 19-Module chassis provides thirty eight fibre runs from only 2U of rack space.

Advanced features include IEEE 802.1Q VLAN and 802.1p Quality of Service prioritization, and Port Access Control, which provides the ability to enable or disable individual ports to control delivery of services. The 2GXT also supports port-level MIB statistics, and reporting real-time packet statistics to provide performance and operational monitoring.

Temperature hardened models are available, and the 2GXT can be DIN-rail mounted with an optional mounting bracket for industrial applications and outdoor deployments.

The 2GXT features user-selectable Link Propagate and Link Segment modes to facilitate quick fault detection, isolation and reporting.

The iConverter 2GXT chassis plug-in module can be used in managed or unmanaged applications. Management provides remote configuration, monitoring and trap notification. Management of the plug-in module is accomplished by installing an iConverter Management Module (NMM2) or Network Interface Device (NID) in the same chassis.

The Management Module can be accessed via SNMP, Telnet, and via a serial port. The 2GXT can be managed with Omnitron’s intuitive, graphic-oriented NetOutlook SNMP Management Software or third party SNMP management software. Management via the Telnet and the serial interfaces have an easy-to-use, menu-driven interface.

The management software can override the physical DIP switch settings such as auto-negotiation, Half or Full-Duplex, and Backplane Selection, and remotely configure additional parameters including rate-limiting, VLAN and Port Access Control. Some of the real-time 2GXT parameters that can be monitored include duplex mode, 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 and error counts.

The iConverter 2GXT supports SNMP trap notification for the monitoring and notification of different network events. Specific 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.

Application Examples

Standalone Dual-Channel Media Converter

In this application diagram, the 2GXT functions as a dual-channel media converter, providing connectivity between two fibre links and two RJ-45 ports on a copper switch. The conversion from copper to fibre are on separate and independent channels, so there is no cross-connection between channels.

2GXT Application Example 1
Chassis-Based Dual-Channel Media Converters

In this application diagram, eighteen 2GXT plug-in modules are installed in a 19-module chassis for high-density fibre distribution from a Gigabit copper switch. Thirty six fibre runs are distributed from a 2-U chassis. An NMM2 Network Management Module is also installed in the chassis, and connected to a Network Management Station for fault notification and remote configuration. At the end each fibre run, an iConverter GX/T2 standalone media converter provides copper to fibre conversion and bridging for connectivity to Fast Ethernet or Gigabit switches at remote locations.

2GXT Application Example 2
Standalone Compact Switch with 1:1 Fibre Protection

The 2GXT can be configured as a four-port switch module with redundant fibre links. In this application, a 2GXT provides protected fibre connectivity to two separate nodes on a resilient ring. Port 1 of the 2GXT is the Active Fibre and port 2 is the Standby Fibre. In the event of link fault detected by Port 1, the 2GXT will switch to the Standby Fibre to maintain connectivity to the ring.
