This fiber optic transceiver is the direct equivalent to Cisco SFP-25G-LR-S for 25Gbps connectivity up to 10km (6.2mi) over LC-terminated Single Mode Fiber (SMF) cable. The optical module has been programmed and tested for seamless integration with Cisco equipment. The 25GbE single-mode fiber module (SFP28) excels in bandwidth-intensive tasks such as virtualization, efficient data migrations, high-performance storage, high-performance computing (HPC), and rapid online content uploads. This MSA-compliant SFP works with network equipment manufactured by Cisco and network equipment from manufacturers that accept uncoded optical modules. Technical specs: 25GBASE-LR SFP28 Data Rate: 25Gbps, Fiber Type: Single Mode Fiber (SMF), Connector: LC, Wavelength: 1310nm Tx/Rx, Distances: Up to 10km (6.2mi), Supports Digital Diagnostics Monitoring (DDM/DOM).
