Product Brief
The SFP-25G-SR is an industry-standard 25Gbps multi-mode fiber transceiver supporting 100m reach over OM4 MMF. Designed for 25GbE switches and routers, it provides cost-effective high-speed connectivity for data center top-of-rack (ToR) deployments and enterprise networks.
Product Details
This SFP28 form-factor transceiver operates at 850nm wavelength with VCSEL laser technology. Compliant with IEEE 802.3by and SFF-8402 standards, it features digital diagnostics monitoring (DDM/DOM) for real-time performance tracking in compatible network equipment.
Key Features
25Gbps Data Rate: Full-duplex over dual LC fiber
100m Reach: On OM4 multi-mode fiber (70m on OM3)
Low Power: <1W typical power consumption
Hot-Swappable: SFP28 MSA-compliant form factor
DOM Support: Real-time temperature, voltage, and power monitoring
Broad Compatibility: Works with Cisco, Juniper, Arista, and other major switches
