Dell 25GbE 850nm 300m SFP28 Network Transceiver

The Dell 0CTW7 is a 25 gigabit Ethernet transceiver that fits any SFP28 slot and delivers fast, fiber-based links throughout your network. Once seated, it gives switches, servers, and storage arrays a reliable multimode fiber connection that can stretch to 300 meters, making it a practical choice for wiring closets, adjacent data halls, or short-reach backbone runs.

Operating at an 850 nm wavelength, the module works with OM3 or OM4 multimode cabling and terminates in an LC duplex connector, so it drops straight into existing fiber trays without adapters. Because it is hot pluggable, you can install or replace it without powering down equipment, minimizing disruption during upgrades or maintenance.

The transceiver also reports real-time operating data through its digital diagnostic monitoring interface. Administrators can track temperature, laser bias current, and optical power from their network management tools, helping them spot potential issues before they affect traffic.

Typical use cases include server virtualization clusters that need more bandwidth than 10 gigabit links can provide, top-of-rack switches that aggregate high-density access ports, and hyperconverged nodes that replicate data across racks. The module is qualified for a broad range of Dell networking and server platforms, so it integrates cleanly with existing Dell infrastructures and carries full vendor support.

Whether you are expanding a private cloud, refreshing an edge network, or building a lab environment for high-performance testing, this transceiver offers a straightforward path to 25 gigabit speeds without the expense of single-mode optics.
