Copper-to-fiber media converter

The Black Box LHC210A is a standalone media converter that bridges a single 10/100Base-TX twisted-pair port to a 100Base-FX fiber link using one SFP slot. It serves network engineers who must extend a Fast Ethernet segment beyond the 100-metre copper limit without replacing existing switches.

SFP slot and AC adapter for flexible deployment

A single SFP expansion slot accepts compatible single-mode or multi-mode transceivers, so the same chassis can address different fiber types and distances. The unit draws power from an included 5 V DC AC adapter, sits on a desk or shelf in a 1 by 2.7 by 3.7 inch metal enclosure, and weighs 11.20 oz for easy placement in wiring closets.

37.28 mile maximum reach over single-mode fiber

With the appropriate single-mode SFP module the converter supports links up to 37.28 miles, while multi-mode optics cover shorter campus runs. Buyers who need Gigabit or 10 Gigabit throughput, PoE pass-through, or managed features such as VLAN tagging will need a different platform.

Questions about this item

Does the SFP slot accept both single-mode and multi-mode transceivers?

Yes, the converter supports single-mode and multi-mode fibre through its single SFP slot, with reach up to 37.28 miles depending on the transceiver used.

What are the exact dimensions for rack or shelf planning?

The standalone unit measures 1 inch high, 2.7 inches wide and 3.7 inches deep, weighing approximately 11.20 ounces.

How is the converter powered and what common mistake should I avoid?

It ships with a 5-VDC AC adapter; the frequent error is inserting the SFP module after power-up instead of before, which can prevent link negotiation.
