Black Box LMC4004A Micro Mini Gigabit Single-Mode Fiber Media Converter

Description

The Black Box LMC4004A is a Micro Mini Gigabit media converter that converts 10/100/1000Base-T copper signals to 1000Base-LX single-mode fiber with SC connectors . This ultra-compact converter weighs only 2.5 ounces and is about the length of a house key, making it ideal for fiber-to-the-laptop and mobile applications where light weight, compact size, and low power requirements are critical. The converter supports distances up to 12 kilometers (7.5 miles) over single-mode fiber, making it suitable for campus and metropolitan area network extensions . The LMC4004A can be powered in multiple ways: via the included AC power supply, through a computer’s USB port (drawing 0.5A at 5VDC), or using the optional wallmount bracket (LMC400-WALL). The RJ-45 port auto-negotiates for speed, duplex mode, and crossover functions, supporting 10BASE-T, 100BASE-TX, and 1000BASE-T Ethernet. When powered via USB, the converter automatically shuts down when the computer turns off, saving energy .
