D-Link SFP+ Module

Designed for data centers, enterprise networks, and demanding edge deployments, the D-Link SFP+ Module delivers high-performance 10GBASE-T connectivity over copper twisted-pair cabling. This compact SFP+ transceiver fits standard SFP+ cages and enables fast, reliable 10 Gbps links between switches, servers, and network storage. With its copper-based RJ-45 interface, it lets you leverage existing cabling investments while scaling your network to support virtualization, cloud workloads, and growing traffic demands. Whether you're upgrading uplinks or extending your internal fabric, this module is built to deliver consistent, enterprise-grade performance.

• 10GBASE-T performance over copper — The module provides multi-gigabit capabilities by transferring data at up to 10 gigabits per second over standard RJ-45 copper cabling. It enables high-throughput uplinks and server connections without requiring fiber replacement, and is optimized for common enterprise cabling, including Cat6a and Cat7. In practical terms, you can deploy this transceiver to connect switches, servers, and top-of-rack devices with minimal latency and robust error handling, even in busy environments where traffic surges occur. The result is a scalable, cost-efficient upgrade path that preserves existing investments while enabling modern 10G architectures.
• Flexible compatibility with 10G networks — Built to slot into SFP+ cages on a wide range of devices that support 10GBASE-T, this module is a versatile upgrade for data centers, campuses, and branch offices. It supports common networking topologies and protocols used in virtualization, distributed storage, and high-performance computing. By adopting a copper-based 10GBASE-T solution, you can align with multi-vendor environments when allowed by hardware compatibility, enabling smoother migrations and simpler capacity planning. This adaptability helps IT teams avoid disruptive forklift upgrades while expanding network capabilities.
• Simple deployment with standard RJ-45 cabling — With a familiar RJ-45 copper interface, installation is quick and straightforward. No fiber cabling or optical interfaces are required for many uplinks, saving time and reducing cabling costs. The module plugs into a standard SFP+ slot, and paired with a compatible switch or NIC, it supports straightforward link establishment, auto-negotiation, and 10G-speed operation. For best results, use high-quality copper cabling (Cat6a or better) and keep runs within recommended distances to maintain signal integrity and minimize reflections or crosstalk in busy data centers.
• Efficient and reliable operation — Copper 10GBASE-T technology has matured to provide reliable, lower-latency links with strong error detection and robust link negotiation. The D-Link SFP+ Module is designed to maintain stable performance under load, with attention to EMI resilience and effective thermal management. In typical deployments, you can expect consistent throughput, predictable latency, and durable operation across a wide range of environmental conditions, from cooled data centers to edge environments. This reliability is crucial for applications such as virtualization, backup and disaster recovery, and large-scale data replication.
• Professional-grade reliability and support — This module is backed by D-Link’s warranty and support ecosystem, ensuring long-term viability in production networks. The design emphasizes ease of maintenance, with straightforward installation, clear link indicators, and compatibility with standard network management workflows. By choosing a reputable 10GBASE-T SFP+ transceiver, you reduce risk and simplify ongoing operations, knowing you have access to technical resources, firmware updates when needed, and vendor assistance if field issues arise in complex multi-vendor environments.
