About This Part
The Juniper Networks Part Number 740-085351 represents a high-performance 400GBASE-DR4 QSFP-DD optical transceiver module, engineered for demanding data center and enterprise networking environments. This module is designed to facilitate 400 Gigabit Ethernet connectivity, leveraging four independent 100Gbps optical channels. Operating at a wavelength of 1310nm, it utilizes single-mode fiber (SMF) for reliable data transmission over distances up to 500 meters. The QSFP-DD (Quad Small Form-Factor Pluggable Double Density) form factor ensures high port density and compatibility with modern networking equipment. Its robust design supports an extended operating temperature range up to 70°C, making it suitable for diverse deployment conditions where thermal resilience is critical for maintaining network integrity and performance. This Juniper 740-085351 transceiver is crucial for building high-capacity network infrastructure, commonly deployed in hyperscale data centers, large enterprise networks, and service provider core networks. It enables high-speed inter-rack connectivity, spine-leaf architectures, and short-reach data center interconnect (DCI) applications, addressing the ever-growing demand for bandwidth. Network operators and cloud service providers utilize these modules to upgrade existing 100GbE or 200GbE infrastructures to 400GbE, ensuring future-proof scalability and reducing network bottlenecks. It integrates seamlessly with Juniper Networks' extensive portfolio of switches and routers, providing a robust solution for high-density, high-throughput network segments where efficiency and reliability are paramount.
