Description
The Cisco SFP-1025G-LR-I is a high-performance 100GBASE-LR QSFP28 transceiver module designed for long-range data center and enterprise networking applications. Built with durability in mind, this industrial-grade transceiver supports extended operating temperatures, making it ideal for deployments in harsh environments. It utilizes a duplex LC connector and supports a maximum link length of up to 10 kilometers over single-mode fiber (SMF), ensuring reliable, high-speed connectivity across large-scale networks. The compact QSFP28 form factor allows for high port density, optimizing space and efficiency in network hardware configurations.
This module supports a data rate of 103.125 Gbps and complies with IEEE 802.3ba 100GBASE-LR4 standards, ensuring interoperability with a wide range of networking equipment. Internally, it features four 25G channels using LAN WDM (wavelength-division multiplexing) technology, which are multiplexed into a single 100G stream for efficient transmission. The digital optical monitoring (DOM) feature allows for real-time monitoring of key parameters such as temperature, voltage, and optical power levels. When buying used, ensure the module has been properly tested and verified to meet performance benchmarks, as its robust design is built to deliver consistent operation even in demanding network environments.
