Description
The Juniper QSFP-100G-LR4-D is a high-performance 100 Gigabit Ethernet transceiver designed for long-range data center and enterprise networking applications. Housed in a compact QSFP28 form factor, it supports data transmission over single-mode fiber (SMF) with a reach of up to 10 kilometers using standard LC duplex connectors. This optical module is fully compliant with IEEE 802.3ba 100GBASE-LR4 and MSA standards, ensuring seamless integration with a wide range of Juniper and third-party networking equipment. Its robust metal housing provides excellent EMI shielding while maintaining efficient thermal performance for dense network environments.
Built with four independent optical lanes, each operating at 25 Gbps, the QSFP-100G-LR4-D uses coarse wavelength division multiplexing (CWDM) to deliver aggregated 100 Gbps throughput. The module includes advanced digital diagnostics monitoring (DDM) for real-time performance tracking of parameters such as temperature, voltage, and optical power levels. Ideal for high-bandwidth applications, it supports hot-swappable functionality, minimizing downtime during upgrades or replacements. When purchased used, careful inspection of the optical components and connector integrity ensures continued reliability and performance in mission-critical deployments.
