Intel E25GSFP28SR 25GBase-SR SFP28 server accessory

SKU CH-95H2-378C5 MPN E25GSFP28SR

25GBase-SR SFP28 transceiver for 25 Gigabit Ethernet over optical fibre, compatible with Intel XXV710 adapters

  • Product typeSFP28
  • Key features1 × 25GBase-SR Network
  • 25 Gbps optical connectivity for high-speed data networking
  • 10 Gbps Ethernet compatibility supports existing network infrastructure
  • SFP28 form factor fits compatible Intel server adapters
  • 25GBase-SR standard enables short-range fibre links
  • Designed for Intel XXV710 network adapter compatibility

Purpose and Audience

This Intel E25GSFP28SR is a 25GBase-SR SFP28 transceiver built for data and optical networking. It connects compatible Intel Ethernet adapters to multimode fibre links at 25 gigabits per second. Network engineers deploying short-range 25G connections in server environments use this module to add or replace a single port. The part is new and supplied as an Intel-branded server accessory.

Who This Suits and Who It Does Not

This module suits administrators expanding 25GBase-SR connectivity on supported Intel Ethernet Network Adapter XXV710 hardware. It provides one optical port over multimode fibre. Buyers who need a different reach, a copper interface, or a form factor other than SFP28 cannot use this part. Systems without a compatible SFP28 cage or matching host adapter will not accept it.

Deciding Specification

The deciding specification is the 25GBase-SR optical interface operating over multimode fibre. This defines the link speed, the signalling standard and the physical medium the transceiver requires. Confirm that your switch or adapter port is rated for 25GBase-SR and that the fibre plant matches before purchasing.

Questions about this item

How often should the 25GBase-SR SFP28 optic be inspected or replaced in a data networking environment?

The Intel E25GSFP28SR is a passive optical transceiver with no moving parts, so it typically requires no scheduled maintenance; replacement is only needed if link errors or physical damage appear.

What is the first limit reached when the SFP28 module runs continuously at 25 Gbps?

The primary sustained-use limit is the module's rated operating temperature range; exceeding it can cause link instability before any other parameter is reached.

How much heat and power does the Intel E25GSFP28SR produce when running all day?

The SFP28 optic draws low power and generates minimal heat, staying within standard SFP28 thermal limits during continuous 25GBase-SR operation.
