Frequently Asked Questions

What is the maximum data rate supported by the Dell SFP28-25G-SR transceiver? +

The Dell SFP28-25G-SR is engineered to deliver high-speed 25GbE connectivity. It is specifically designed to handle data rates of 25 Gigabits per second, making it an ideal choice for upgrading server-to-switch links or high-bandwidth uplinks within modern data center environments requiring low latency and consistent throughput.

What type of cabling is required for the Dell SFP28-25G-SR to function correctly? +

This transceiver is a Short Reach (SR) module intended for use with multi-mode fiber optic cabling. It utilizes an LC duplex connector interface and is optimized for OM3 or OM4 fiber types. Users should ensure they are deploying the appropriate multi-mode infrastructure to achieve the specified reach and signal integrity required for 25G performance.

How does the SFP28-25G-SR perform compared to standard 10G SFP+ modules? +

The SFP28 form factor is physically compatible with many SFP+ ports but provides significantly higher bandwidth. By migrating to 25G optics, network administrators can achieve 2.5 times the bandwidth of traditional 10G connections, effectively reducing bottlenecks in high-density server deployments without the immediate need to move to 40G or 100G architectures.

Is the Dell SFP28-25G-SR compatible with third-party switch manufacturers? +

While this module is a genuine Dell component optimized for Dell Networking switches, compatibility with non-Dell hardware can vary based on the manufacturer’s port restrictions. It is highly recommended to verify that your specific switch firmware supports generic or Dell-branded SFP28 transceivers before deployment to ensure proper link negotiation and optical communication.

What is the typical reach distance for the SFP28-25G-SR using OM4 fiber? +

When paired with high-quality OM4 multi-mode fiber, the SFP28-25G-SR is capable of reaching distances up to 100 meters. This makes it a perfect solution for top-of-rack or end-of-row cabling scenarios within a standard server room or data center where short-range, high-speed connectivity is essential for interconnected infrastructure.

Does the SFP28-25G-SR support Digital Optical Monitoring (DOM)? +

Yes, this transceiver features advanced diagnostic capabilities known as Digital Optical Monitoring. This allows network administrators to monitor real-time parameters, including optical output power, input power, temperature, and transceiver supply voltage directly from the switch console. This data is critical for proactive maintenance and quickly identifying potential signal degradation before it results in network downtime.

What are the power consumption requirements for the Dell SFP28-25G-SR? +

This module is designed for efficiency, operating within the standard power envelope for SFP28 transceivers. By utilizing low-power optical components, it minimizes the heat footprint within the switch chassis. It is advisable to check your switch's total power budget per port to ensure the cumulative power draw remains within the acceptable parameters for your specific hardware configuration.

Can I use the SFP28-25G-SR in an SFP+ 10G port? +

While SFP28 and SFP+ ports share the same physical form factor, backward compatibility depends entirely on the switch hardware and software support. Some Dell switches allow a 25G port to downshift to 10G, but using a 25G optic in a legacy 10G-only port is generally not supported. Always consult the specific datasheet for your switch model to confirm auto-negotiation capabilities.

How can I obtain a bulk quote for the Dell SFP28-25G-SR modules? +
