About this product
StarTech Cisco SFP-25G-SR-S Compatible SFP28 Module, 25Gbps Multimode Fiber (MMF), 100m (328ft), LC Connector, 850nm, MSA 25 Gigabit Optical Transceiver
This fiber optic transceiver is the direct equivalent to Cisco® SFP-25G-SR-S for 25Gbps connectivity up to 100m (328ft) over LC-terminated Multimode Fiber (MMF) cable. The optical module has been programmed and tested for seamless integration with Cisco® switches and routers to ensure compatibility and reliability.
Maximize Bandwidth
The 25GbE SFP28 excels in bandwidth-intensive tasks such as virtualization, efficient data migrations, high-performance storage, high-performance computing (HPC), future-proofing a network, and rapid online content uploads.
Technical Specifications
- 25GBASE-SR SFP28
- Data Rate: 25Gbps
- Fiber Type: Multimode Fiber (MMF)
- Connector: LC
- Wavelength: 850nm Tx/Rx
