Media Converter 100 Mbps Fiber

The Black Box LHC043A-R4 converts 10/100-Mbps copper Ethernet to 100-Mbps simplex singlemode fiber at 1550/1310 nm. It extends network reach up to 2 km using an SC connector and an RJ45 port with autocross for MDI-II/MDI-X. The unit operates from 0 to 50 °C and meets EN62368 compliance.

Installers Needing Compact Fiber Links

This converter suits technicians who must bridge copper and fiber in tight spaces such as wall boxes or DIN rails. It is not for buyers who need Gigabit throughput, duplex fiber interfaces, or PoE pass-through on the copper side. The fixed 100-Mbps rate also rules out high-bandwidth backbone upgrades.

USB and PowerTray Power Options

The included 100-240 VAC adapter provides standard mains power. The optional LHC021A cable lets the converter draw 5 V from a PC USB port, while the LHC018A-AC-R2 PowerTray supports rackmount installations with multiple units. These choices remove the need for dedicated outlets at every endpoint.

Questions about this item

What type of twisted-pair cable must I already have to connect the RJ45 port on the LHC043A-R4?

You need CAT5 or better, shielded or unshielded, for the RJ45 connection.

Will the SC singlemode fiber interface on this converter work with my existing 62.5/125 µm duplex fiber patch cords?

Yes, the converter accepts 50/125 µm or 62.5/125 µm singlemode duplex fiber on the SC port.

Which LEDs on the LHC043A-R4 confirm the fiber link is transmitting and receiving correctly?

The fiber port shows separate XMT and RCV LEDs; both lit mean the link is active in both directions.
