25g SFP Transceiver

The 25G SFP28 Transceiver is a high-performance, hot-pluggable optical module designed for 25 Gigabit Ethernet applications in data centers, cloud computing, and enterprise networks. Compliant with SFF-8402 and IEEE 802.3by standards, these transceivers convert electrical signals to optical for transmission over multi mode or single-mode fiber, enabling reliable connectivity at distances up to 100 meters (SR) or 10 kilometers (LR). The compact SFP28 form factor provides twice the density of traditional SFP+ modules, making them ideal for high-port-count switches and servers. With low power consumption and digital diagnostics monitoring (DDM) capabilities, these transceivers deliver the performance and reliability required for next-generation data center infrastructure.

Applications

 

High-Bandwidth Optical Connectivity for Modern Networks

  • Data Center Leaf-Spine Architecture: Used in 25G leaf-spine network topologies for interconnecting servers and switches across rows, providing high-density, cost-effective optical connectivity.
  • Top-of-Rack (ToR) Switching: Deployed in 25G ToR switches connecting to servers within the same rack or adjacent racks, enabling high-bandwidth server connectivity with flexible cabling.
  • Cloud & Hyperscale Data Centers: Used in large-scale deployments requiring reliable, high-density optical connectivity across data center floors with distances exceeding copper capabilities.
  • Storage Area Networks (SAN): Integrated into 32G Fibre Channel storage environments for connecting servers to storage arrays, backup systems, and SAN switches.
  • High-Performance Computing (HPC): Deployed in compute clusters requiring low-latency, high-bandwidth optical links for parallel processing, AI/ML training, and scientific computing workloads.
  • Enterprise Networks: Used in campus core networks, distribution switches, and server connections requiring 25G uplinks or long-distance connectivity between buildings.
  • Telecommunications Infrastructure: Deployed in 5G base stations, edge data centers, and mobile backhaul networks requiring reliable 25G optical transport.
  • Test & Measurement: Used in network testers, protocol analyzers, and lab environments for validating 25G network performance and interoperability testing.

Star Reviews From Customers

 

1.Mike, data center engineer in Virginia
"These SFP28 SR transceivers work great with our Arista switches. The 100m reach covers our row-to-row connections. Digital diagnostics are handy for monitoring signal strength. No compatibility issues. Good value compared to OEM."


2.Priya, network architect in Bangalore
"Deployed these LR modules for 10km campus links between buildings. Plug and play with Cisco gear. The industrial temperature version handles outdoor cabinets. EEPROM programming matched our requirements. Reliable performance."


3.Dave, storage admin in Texas
"32G Fibre Channel environment needed SR optics for storage arrays. These transceivers work with Brocade switches. Zero bit errors after a year. The 300m reach covers our data center floor. Good quality."
