Product Description
The Compaq 378928R-B21 represents a versatile solution for extending Gigabit Ethernet connectivity using standard copper cabling. As an SFP (Small Form-factor Pluggable) module, it offers a compact and hot-swappable interface that plugs into compatible network ports on switches, routers, or servers. Unlike typical fiber optic SFPs, this module terminates in an RJ-45 connector, enabling connections over familiar Ethernet cables. This transceiver is designed to support data rates of 1 Gb/s, commonly known as Gigabit Ethernet. It allows network administrators to leverage existing copper infrastructure for distances up to 100 meters, providing a cost-effective alternative to deploying new fiber optic runs for shorter links. The RJ-45 interface ensures compatibility with a wide range of standard Ethernet patch cords. Primarily intended for use with Compaq and HP networking equipment, the 378928R-B21 facilitates flexible network design. It can be used to connect devices in different rooms, across floors, or within a wiring closet where copper cabling is already in place. This makes it particularly useful for network upgrades or expansions where the physical layout or cabling limitations might otherwise pose a challenge.
