The QSFP-100GBASE-LR4 is a 100 Gigabit Ethernet optical transceiver module designed for long-range data transmission over single-mode fiber (SMF). It operates at a wavelength of 1310 nm and supports distances up to 10 kilometers. This module utilizes four independent optical communication lanes, each capable of transmitting data at 25.78 Gbps, aggregating to a total data rate of 100 Gbps. It features a duplex LC connector and supports Digital Diagnostic Monitoring (DDM) for real-time monitoring of operating parameters. The QSFP-100GBASE-LR4 is compliant with the IEEE 802.3ba 100GBASE-LR4 standard and is commonly used in data center interconnects, enterprise core networks, and service provider backbones. citeturn0search6
