Single-port media converter

The Black Box Innovations LMC4000A is a wall-mountable SFP transceiver that bridges twisted-pair and optical-fiber links at Gigabit Ethernet speeds. One RJ-45 port handles 10/100/1000Base-TX traffic while the single SFP slot accepts 1000Base-X modules for fiber uplinks. Power is supplied by an external adapter included with the unit.

Suits network teams extending copper runs with fiber

Technicians who need a compact, single-channel converter for point-to-point fiber links will find the form factor and dual-media support convenient. Teams requiring multi-port aggregation, managed switching features or in-band management interfaces should evaluate other platforms.

One RJ-45 port and one SFP slot

The device provides exactly one copper port and one SFP expansion slot, so each unit converts a single Ethernet segment. Confirm that your link design calls for a one-to-one media conversion before ordering.

Questions about this item

Should I choose the single SFP slot or the RJ-45 port for my fibre link?

Use the SFP slot for optical fibre; the RJ-45 port handles copper twisted pair at 10/100/1000Base-TX.

What does the 1000Base-X rating deliver on a live Gigabit Ethernet segment?

It provides a full-duplex 1000 Mb/s optical link when a compatible SFP module is installed.

How does the SFP expansion slot limit the maximum network speed?

The slot accepts any standard SFP transceiver, so the practical ceiling is the 1000Base-X Gigabit Ethernet rate.
