Description

Black Box LMC4000A-KBK Gigabit Ethernet Media Converter

Overview

The Black Box LMC4000A-KBK is a critical component for extending network infrastructure beyond the standard Ethernet cable length. This media converter bridges a 10/100/1000Base-T copper connection to a 1000Base-X SFP fiber optic link, enabling data transmission over much longer distances. It's particularly useful in large-scale surveillance systems where cameras might be deployed far from the network closet, or in industrial environments requiring robust, interference-free connectivity. The LMC4000A-KBK is designed for reliable operation without an included power supply or case, allowing for integration into existing chassis or custom power solutions.

Compatibility

This media converter is designed to interface with standard 10/100/1000Base-T Ethernet ports found on network switches, routers, and IP cameras. It requires a compatible 1000Base-X SFP transceiver (sold separately) to establish the fiber optic link. It is compatible with network devices that support Gigabit Ethernet connectivity and adhere to IEEE 802.3ab (for copper) and IEEE 802.3z (for fiber) standards. It integrates seamlessly with network infrastructure from various vendors, provided the SFP module meets the required specifications.

Installation Notes

Installation requires a compatible 1000Base-X SFP transceiver inserted into the designated slot. The RJ-45 port connects to the copper Ethernet device, and the fiber optic connection is made via the SFP module. This unit is designed for chassis-based systems or applications where external power supplies are managed separately; it does not include its own power adapter or enclosure. Ensure the operating environment meets the specifications of the chosen SFP module and any surrounding equipment.
