Extreme Networks 25G SFP28 SR Optical Transceiver

The Extreme Networks 25G SFP28 SR Optical Transceiver is a short-reach transceiver module designed to support 25 Gigabit Ethernet connectivity over multi-mode fiber (MMF) infrastructure. Operating at wavelengths optimized for data center environments, this module delivers the electrical-to-optical conversion required for modern high-density server deployments transitioning from 1GbE and 10GbE architectures. The SFP28 form factor enables compact, hot-swappable installation in server network interface cards (NICs) and top-of-rack (ToR) switching fabric without requiring architectural modifications to existing equipment mounting structures.

Designed to support enterprise-scale server refresh cycles, the 25G SFP28 SR transceiver addresses sustained demand from organizations standardizing on 25GbE server connectivity. This module integrates digital diagnostics capabilities for real-time monitoring of optical power levels, temperature, and bias current—critical for predictive maintenance and operational visibility in virtualized and containerized compute environments. The transceiver's compliance with MSA (Multi-Source Agreement) specifications ensures interoperability across heterogeneous infrastructure deployments.

Launched in Q1 2023, this transceiver reflects Extreme Networks' commitment to enabling customers accelerating their migration to higher-bandwidth server-to-leaf topologies while maintaining compatibility with installed base fiber plant investments.

Ideal for

• High-performance computing (HPC) cluster interconnects requiring deterministic, low-latency server-to-switch fabric communication
• Virtual desktop infrastructure (VDI) farms consolidating multiple workstations onto hypervisor clusters with elevated throughput demands
• Database server clusters supporting real-time analytics and OLTP workloads requiring sustained 25Gbps uplink capacity
• Containerized application platforms and Kubernetes node networking where per-pod bandwidth isolation demands exceed 10GbE capabilities
• Storage server deployments (NAS/SAN) supporting concurrent multi-client I/O with sub-millisecond latency requirements
• Enterprise video production and media asset management environments requiring uncompressed or lightly-compressed file transfer over LAN
