Compact Gigabit Media Converter

The Black Box LMC4000A converts a single 10/100/1000Base-TX copper link to a 1000Base-X fibre connection using one SFP slot. It is built for network teams who need to extend a Gigabit Ethernet segment over optical fibre without a full-sized chassis.

SFP Slot Determines Reach

The only specification that decides whether this unit fits the link is the SFP transceiver you install, because the converter itself has no fixed fibre interface. You must supply an SFP module that matches the required wavelength, distance and fibre type for the target run.

Wall-Mount Power Supply Included

A wall-mountable power adapter ships with the converter, so the device can be powered directly from a mains outlet without a separate rack supply. The compact enclosure measures 0.8 by 1.8 by 2.3 inches and weighs 2.50 oz, allowing discreet placement in tight spaces.

Questions about this item

What does the 10/100/1000Base-TX to 1000Base-X conversion mean for my network?

It lets you connect a standard copper Ethernet link at up to 1 Gbps to a fibre SFP module running at 1 Gbps, extending the link distance beyond copper limits.

Which SFP standard does the slot follow and what speed does it cap at?

The single SFP slot accepts standard duplex fibre modules and is limited to 1000 Mbps by the 1000Base-X port specification.

What physical space and mounting does the converter need?

The unit measures 0.8 in high, 1.8 in wide and 2.3 in deep, weighs 2.50 oz and is designed for wall mounting with the included power adapter.
