Dell 3G84K

Overview

The Dell 3G84K is a 10Gbe SR SFP+ transceiver designed to provide high-speed 10 Gigabit Ethernet connectivity over multimode fiber. It operates at an 850 nm wavelength and supports transmission distances up to 300 meters with OM3 or OM4 fiber, making it suitable for data centers, server rooms, and campus backbone networks. This module fits directly into compatible switch or server ports, allowing network administrators to upgrade bandwidth without replacing existing hardware.

Key features

• Supports 10 Gbps data transfer rate for fast and efficient network communication
• Hot-pluggable SFP+ form factor enables easy installation and replacement without powering down equipment
• Compatible with Dell devices using Broadcom 57810S SFP+ adapters, ensuring seamless integration
• Operates at 850 nm wavelength with duplex LC connectors for reliable short-range fiber connections
• Built-in digital diagnostics provide real-time monitoring of temperature, voltage, laser bias, and optical power to maintain optimal link performance
• Supports transmission distances up to 300 meters over OM3 or OM4 multimode fiber, covering most short-range fiber deployment needs

Connectivity and compatibility

This transceiver is designed to fit into SFP+ ports on Dell switches and servers that use Broadcom 57810S network cards. Its duplex LC interface supports standard multimode fiber cables, making it easy to integrate into existing fiber infrastructure. The hot-pluggable design allows network teams to add or replace modules without interrupting network operations, which is critical for maintaining uptime in enterprise environments.

Ideal uses and environments

The Dell 3G84K is well suited for short-range fiber connections within data centers, including top-of-rack switch uplinks, server-to-storage links, and campus backbone connections. Its 300-meter reach covers most typical fiber runs in these environments, providing the bandwidth needed for virtualized clusters and high-performance computing setups. Network administrators looking to upgrade to 10 GbE speeds without overhauling their entire infrastructure will find this transceiver a practical and cost-effective choice.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
