Micro Mini Media Converter

The Black Box LMC4001A converts copper Ethernet to multimode fibre for desktop or mobile use. It targets installers who need a lightweight link up to .5 kilometres without a full chassis. The unit weighs 2.5 ounces and fits behind a PC.

USB or adapter power

The converter draws power from a USB port for portable operation or from the included wall-mountable adapter. Plug-and-play autonegotiation removes manual configuration. LED indicators show power, copper and fibre link status.

Half-kilometre multimode limit

The 850 nm transceiver reaches 1640.42 feet over duplex multimode fibre with ST connectors. Jumbo frames up to 10240 bytes pass through. Copper port negotiates 10, 100 or 1000 Mbps. Distance and fibre type fix the practical range.

Questions about this item

Does the ST fiber connector on the LMC4001A need periodic cleaning or replacement?

The ST duplex connector should be inspected and cleaned with a lint-free wipe and isopropyl alcohol whenever signal loss appears; no scheduled replacement interval is defined by the manufacturer.

What is the maximum link distance before signal degradation on this 850 nm multimode transceiver?

The LMC4001A is rated for 0.5 km (1640.42 ft) over 850 nm multimode fiber; beyond that distance attenuation and modal dispersion will limit reliable operation.

How much heat does the USB-powered converter produce when running continuously at 1000 Mbps?

The unit draws power from a USB port or the included wall adapter and has no fan; its compact 2.5-ounce enclosure dissipates heat passively, so surface temperature stays low during all-day operation.
