Description
The Black Box LFP443 is a specialized SFP (Small Form-factor Pluggable) transceiver module designed to bridge the gap between fiber optic infrastructure and copper Ethernet networks. It supports the 1000Base-T standard, enabling Gigabit Ethernet speeds over standard copper cabling, specifically Cat 5e or Cat 6 Ethernet cables. This transceiver features an integrated RJ-45 connector, allowing for direct connection to standard Ethernet patch cords. It has a maximum transmission distance of 100 meters, which is the standard limit for Gigabit Ethernet over copper. The LFP443 is ideal for applications where extending Gigabit Ethernet connectivity is required without the need for fiber optic cabling, such as connecting devices within an office floor or across a data center rack. The LFP443 is part of the LFP440 Series and is designed for hot-swappable insertion into network devices equipped with SFP ports. This provides a flexible and convenient way to add 1000Base-T connectivity to switches, routers, or other network equipment, offering a cost-effective solution for short-reach copper-based Gigabit Ethernet deployments.
