About This Part
The Juniper 740-045627 is a high-performance Quad Small Form-Factor Pluggable (QSFP+) transceiver module, designed for robust 40 Gigabit Ethernet (40GbE) connectivity. This specific module, identified as QSFP-40G-SR-300M, operates over multimode fiber (MMF) and is engineered to support short-reach applications. It adheres to the IEEE 802.3ba standard for 40GBASE-SR4, utilizing four independent transmit and receive channels, each operating at 10 Gbps, to achieve an aggregate data rate of 40 Gbps. The module typically employs 850nm wavelength VCSEL (Vertical Cavity Surface Emitting Laser) technology and is capable of reaching distances up to 300 meters over OM3 multimode fiber or 400 meters over OM4 multimode fiber. Its hot-pluggable QSFP+ form factor ensures ease of installation and replacement in compatible network equipment, providing a high-density, low-power solution for inter-switch links and server connectivity within data centers. This Part Number 740-045627 is a critical component for high-bandwidth network infrastructure. This Juniper Networks QSFP+ transceiver is primarily deployed in data center environments, enterprise networks, and high-performance computing (HPC) clusters where high-density, high-speed interconnects are essential. It is commonly installed in Juniper Networks switches, routers, and other networking platforms that support QSFP+ ports, facilitating uplink connections, inter-switch links (ISL), and server-to-switch connectivity. Telecommunications operators and large enterprises leverage this module to build or expand their core and aggregation layers, ensuring sufficient bandwidth for demanding applications like virtualization, cloud services, and big data analytics. The 40GBASE-SR4 standard makes it an ideal solution for short-distance, high-throughput connections within a single rack or across adjacent racks, effectively solving bandwidth bottlenecks and enabling seamless data flow between critical network elements. It serves as a vital upgrade path for existing 10GbE infrastructures, providing a significant boost in capacity without requiring a complete overhaul of the cabling plant when multimode fiber is already present.
