Overview

About the Omnitron Systems miConverter GX/T 1239-0-0W

The miConverter GX/T is a miniature 10/100/1000BASE-T copper to 1000BASE-X fiber media converter that supports jumbo frames. The miConverter GX/T miniature Ethernet media converters provide cost-effective copper-to-fiber connectivity solutions. Due to their size, portability, and low power consumption, they are ideal for fiber-to-the-desktop/laptop under the desk deployments and mission-critical field diagnostic applications.

The miConverter GX/T features fixed fiber connectors and Small Form Pluggable (SFP) transceivers. ST, SC and LC fixed fiber connectors support multimode, single-mode, and single-mode single-fiber. 100BASE-X and 1000BASE-X SFP transceivers enable adaptability to different data rates, fiber types and wavelengths, including Coarse Wave Division Multiplexing (CWDM) wavelengths to increase the bandwidth capacity of fiber infrastructure.

The Plug-and-Play capability of the miConverter GX/T simplifies fiber-to-the-laptop and fiber-to-the-desktop deployments. Both the fiber port and the RJ-45 port support auto-negotiation to achieve the best possible mode of operation (speed, duplex mode and Pause mode) between the devices. The auto-negotiation feature can be disabled on both ports (for manual configuration) using DIP-switches on the module. This is useful in a situation where the GX/T is connected to a non-negotiating device and the configuration parameters must be set manually.

Network flow control is managed by the Pause function (configured via auto-negotiation or manually) that prevents network congestion on both the RJ-45 and fiber ports. When Pause is enabled and the device is experiencing network congestion, it will send out a Pause signal to its link partner, instructing it to slow down data transmission.

The GX/T generates a remote fault indication when it detects link fault conditions, and reports detection of these signals by displaying status on the LED. Through user DIP-switch configuration, the detection of these indicators or link modes can also be propagated to the other port on the GX/T as a means of notifying connected end-devices of the link fault.

Visual diagnostic information is provided through LED indicators that assist in network installation and maintenance. The LEDs report the availability of power, port activity and link status and speed.

The miConverter GX/T combines Gigabit Ethernet connectivity with the lightweight design and low-power consumption required for both permanent deployment and temporary facilities.
