Fs.com SFP-10GSR-85, 10GBASE-SR SFP+ 850nm 300m MMF Transceiver Module

Network upgrades often stall because the existing fibre link can’t keep up with growing data demands. The Fs.com SFP-10GSR-85, 10GBASE-SR SFP+ 850nm 300m MMF Transceiver Module solves this by delivering reliable 10 Gbps connectivity over multimode fibre, letting you expand bandwidth without costly cabling changes. It plugs into any SFP+ slot and instantly boosts performance for data centres, campus networks and high-speed storage.

Fs.com SFP-10GSR-85, 10GBASE-SR SFP+ 850nm 300m MMF Transceiver Module - a clear answer to bandwidth bottlenecks

When your network struggles to move large files or support virtualised workloads, latency and packet loss can cripple productivity. This transceiver addresses those issues by providing a stable 10.3125 Gbps link that works over standard OM3/OM4 multimode fibre up to 300 m or 400 m respectively. Its VCSEL transmitter and PIN receiver ensure low error rates, while built-in DDM monitoring lets you keep an eye on temperature and optical power, preventing unexpected downtime. The module complies with IEEE 802.3ae and multiple SFF standards, guaranteeing compatibility with a wide range of switches and routers.

Benefits 

You gain ultra-fast 10 Gbps throughput that handles demanding applications such as video streaming, database replication and cloud services. The low power consumption (≤1 W) reduces heat and energy costs, while the robust MTBF of 11.3 million hours ensures long-term reliability. Built-in DDM support gives real-time diagnostics, helping you spot issues before they affect users. Compatibility with both OM3 and OM4 fibre lets you reuse existing cabling, saving on installation expenses. Finally, the module’s compact SFP+ form factor makes it easy to install and replace without disrupting operations.
