Frequently Asked Questions

What is the maximum reach of the Dell SFP28-25G-SR-85C transceiver? +

The Dell SFP28-25G-SR-85C is a short-reach optical transceiver designed for high-speed data center environments. When utilizing OM4 multi-mode fiber, it supports reach distances up to 100 meters. This makes it an ideal choice for short-run connections between switches, servers, and storage arrays within the same rack or row.

Which networking standards does the Dell SFP28-25G-SR-85C module support? +

This module adheres to the 25GBASE-SR Ethernet standard. It utilizes 850nm wavelength technology over multi-mode fiber to provide high-bandwidth connectivity. It is specifically engineered to comply with IEEE 802.3by specifications, ensuring reliable, low-latency performance in high-density enterprise environments requiring 25 Gigabit Ethernet throughput.

Is the SFP28-25G-SR-85C backward compatible with 10G SFP+ ports? +

While the SFP28 form factor is physically compatible with SFP+ slots, operational compatibility depends on the specific hardware platform's support for auto-negotiation and speed down-clocking. Please consult your host device's documentation to confirm if the switch port supports 10G operation while using 25G SFP28 optics, as not all systems support mixed-speed transitions.

What type of optical cabling is required for the Dell SFP28-25G-SR-85C? +

This transceiver is designed for use with multi-mode fiber optic cabling, specifically supporting OM3 and OM4 standards. For optimal performance and to achieve the maximum specified reach of 100 meters, OM4 laser-optimized fiber is recommended. It uses a standard Duplex LC connector interface for reliable connectivity to your fiber patch panels.

How does the SFP28-25G-SR-85C help optimize high-performance data center cooling? +

The module is designed with power efficiency in mind, operating at low power levels to minimize thermal output within dense switch chassis. By maintaining a strict power budget, it contributes to overall facility energy savings and helps reduce the cooling load in high-density deployments where many transceivers are installed in close proximity.

Can I use the Dell SFP28-25G-SR-85C in non-Dell networking equipment? +

Dell transceivers are primarily validated for use within Dell networking infrastructure. While some third-party platforms may recognize the standard SFP28 interface, cross-vendor compatibility can lead to operational errors or initialization failures. For maximum stability and consistent performance, we recommend deploying these modules within validated Dell switch and server environments.

What is the primary use case for 25G SFP28 optics in an enterprise network? +

The 25G SFP28-25G-SR-85C is predominantly used for server-to-switch uplinks and high-speed inter-switch links. It provides a significant bandwidth upgrade over traditional 10G connections, making it perfect for modern virtualization, cloud computing, and high-performance computing clusters that require increased throughput to prevent network bottlenecks.

How should I handle and install the SFP28-25G-SR-85C to ensure longevity? +

Always maintain a clean environment when handling optical components. Keep the dust cap on the LC connector port until you are ready to insert the fiber patch cable. When installing the transceiver, ensure it is fully seated in the SFP28 cage until the latch clicks, and avoid touching the optical bore to prevent signal degradation.
