About This Part
The Ericsson RDH90120/49800 R4A is a high-performance Small Form-Factor Pluggable (SFP) transceiver designed for robust 1 Gigabit Ethernet connectivity over copper cabling. This module, identified by Part Number RDH90120/49800 R4A, adheres to the IEEE 802.3ab 1000BASE-T standard, enabling full-duplex data transmission at 1 Gbps. It features an industry-standard RJ45 connector, facilitating seamless integration into network devices equipped with SFP ports. The primary function of this SFP transceiver is to provide reliable, short-reach data links, specifically supporting distances up to 100 meters when deployed with Category 5, Category 5e, or Category 6 unshielded twisted-pair (UTP) copper cables. Its hot-pluggable design ensures flexibility and ease of maintenance in active network environments, making it an essential component for extending Gigabit Ethernet capabilities within data centers, enterprise networks, and telecom infrastructure where copper connectivity is preferred or required. This Ericsson 1000BASE-T SFP transceiver is typically deployed in a wide array of networking equipment, including Ethernet switches, routers, network interface cards (NICs), and media converters that feature standard SFP slots. Its versatility makes it suitable for various critical applications within telecommunications networks, data centers, and large enterprise environments. Operators and industries leverage this module for connecting servers to top-of-rack switches, interconnecting distribution and access layer switches, or extending existing copper-based Gigabit Ethernet networks without requiring costly fiber optic infrastructure. It effectively solves the challenge of bridging network segments over short to medium distances using ubiquitous copper cabling, offering a cost-effective alternative to fiber for in-cabinet or intra-room connections. Furthermore, it serves as an ideal upgrade path for legacy 10/100 Mbps copper links, providing a significant bandwidth increase while utilizing existing cabling infrastructure, thus minimizing deployment complexity and capital expenditure.
