Brand: Cisco · SKU: SFP-10/25G-LR-S · MPN: SFP-10/25G-LR-S · Category: Networking
The Cisco SFP-10/25G-LR-S is a high-performance, dual-rate SFP28 optical transceiver module designed for 10-Gigabit and 25-Gigabit Ethernet connectivity. It operates over single-mode fiber (SMF) with a maximum reach of 10 kilometers at a wavelength of 1310nm. This hot-swappable module provides a seamless migration path from 10G to 25G without the need to replace existing fiber infrastructure. It is fully compliant with the SFP28 Multi-Source Agreement (MSA), IEEE 802.3by (25GBASE-LR), and IEEE 802.3ae (10GBASE-LR) standards. Featuring Digital Optical Monitoring (DOM), it allows real-time access to operating parameters such as transceiver temperature, laser bias current, transmitted optical power, and received optical power. It is ideal for data center backbones, campus distribution, and enterprise networking environments requiring reliable long-distance links.
