The Cisco SFP-25G-LR is a 25GBASE-LR SFP28 transceiver module engineered for long-range, high-speed data connectivity across enterprise and data center networks. Operating over single-mode fiber (SMF), this optical module supports 25 Gbps data rate and extends transmission distances up to 10 km, making it perfect for backbone, aggregation, and inter-switch links.
With LC duplex connectors and operation at a 1310 nm wavelength, the SFP-25G-LR provides superior optical performance with low power consumption and excellent reliability. It is hot-swappable, Digital Optical Monitoring (DOM) enabled, and fully compliant with SFF-8402 and IEEE 802.3by 25GBASE-LR standards.
Ideal for use with Cisco switches, routers, and network interface cards, this module ensures seamless integration, consistent performance, and simplified network expansion for modern high-speed environments.
