About This Part
The Juniper Networks Part Number 740-085349 is a high-performance 400 Gigabit Ethernet Quad Small Form-Factor Pluggable Double Density (QSFP-DD) optical transceiver module. Engineered by Juniper Networks, this module adheres to the 400GBASE-FR4 standard, designed for robust and high-bandwidth interconnects within data centers, enterprise networks, and service provider infrastructures. Its QSFP-DD form factor ensures high port density, crucial for modern networking equipment. The 740-085349 operates over four independent optical lanes, each transmitting at 100Gbps, for an aggregate data rate of 400Gbps. Utilizing a LAN-WDM grid at approximately 1300nm wavelengths, this transceiver is optimized for single-mode fiber (SMF) connections, supporting link distances of up to 2 kilometers. This technical specification makes it an ideal solution for medium-reach optical links requiring substantial data throughput. The Juniper 740-085349 transceiver is deployed in critical networking infrastructure, including high-density switches, routers, and data center interconnects that feature QSFP-DD ports. Its primary application lies in enabling 400 Gigabit Ethernet links between core network devices, spine-and-leaf architectures, and inter-building connections within large campus environments or metropolitan area networks. Cloud service providers, hyperscale data centers, and telecommunications operators leverage this module to meet the escalating demand for bandwidth, facilitating rapid data transfer for applications such as artificial intelligence, machine learning, and high-performance computing. This transceiver effectively addresses the challenge of upgrading existing 100G or 200G infrastructure to 400G, providing a cost-effective and scalable path for network expansion without requiring a complete overhaul of the fiber plant for distances up to 2km.
