Compact Gigabit Media Converter

The Omnitron 1639-0-1 is a portable media converter that bridges 10/100/1000Base-T copper Ethernet to 1000Base-X fiber via an SFP slot. It targets field technicians, mobile workers and military personnel who need a lightweight, pocket-sized link between fiber infrastructure and a laptop RJ-45 port. USB power removes the requirement for an AC outlet in remote locations.

Upgrade from Bulkier Converters

This unit replaces larger, AC-dependent media converters when portability and low power draw are priorities. The jump is worth it for teams deploying temporary fiber-to-the-laptop links or operating in vehicles and field sites where space, weight and outlet access are constrained. Fixed rackmount installations with stable power gain no advantage from the smaller form factor.

Build Integration Needs

The converter requires an SFP transceiver module for the fiber side and a standard Ethernet patch cable for the copper side. A host USB port or the included US AC adapter supplies power, freeing the deployment from dedicated power wiring. The 0.8 by 1.8 by 2.3 inch chassis fits in a laptop bag pocket, leaving rack space and cable management unused.

Questions about this item

Will the 0.8 x 1.8 x 2.3 inch SFP module fit my switch cage?

The 1639-0-1 measures 0.8 inch high, 1.8 inch wide and 2.3 inch deep, matching the standard SFP form factor used in most Gigabit switches.

How do I install the transceiver and what step is often missed?

Slide the module into the SFP slot until it clicks, then connect the RJ-45 patch cable; the step often missed is removing the dust plugs from both the optical port and the RJ-45 jack before linking.

When will the RJ-45 port or the module need replacement?

The RJ-45 jack is rated for repeated insertions and the electronics are solid-state; replace only if the link fails after verifying cables and switch ports.
