About This Part
The Juniper Networks Part Number 740-021309 is a high-performance, hot-pluggable SFP+ (Small Form-Factor Pluggable Plus) optical transceiver module. This module is specifically engineered for 10 Gigabit Ethernet applications, providing robust and reliable data transmission over single-mode fiber optic cables. Adhering to the 10GBASE-LR standard, it operates at a nominal wavelength of 1310nm, enabling long-reach connectivity up to 10 kilometers. Its primary function is to convert electrical signals into optical signals for transmission and vice versa, facilitating high-bandwidth communication between network devices such as switches, routers, and network interface cards. The SFP+ form factor ensures compatibility with a wide range of Juniper Networks platforms, offering a compact and efficient solution for high-density network deployments. It features a duplex LC connector for optical interface, ensuring secure and standardized fiber connections. This transceiver is crucial for extending network segments where high data rates and significant distances are required, maintaining signal integrity and performance across the link. The Juniper 740-021309 transceiver is widely deployed in mission-critical network environments requiring high-speed, long-distance optical connectivity. It is commonly installed in core, distribution, and access layers of enterprise networks, as well as within large-scale data centers and telecommunications service provider infrastructures. This module seamlessly integrates with various Juniper Networks platforms, including their extensive range of Ethernet switches (such as the EX and QFX Series) and routers (like the MX Series), providing essential uplink and inter-switch links. Telecom operators leverage this module for metropolitan area networks (MANs) and for connecting central offices to remote aggregation points, while cloud providers utilize it for high-bandwidth data center interconnects (DCIs) and server-to-switch uplinks. It addresses the critical need for reliable 10GbE connectivity over distances up to 10km, solving challenges associated with network expansion, backbone upgrades, and the consolidation of distributed IT resources. This SFP+ module serves as a vital component for upgrading existing 1 Gigabit Ethernet infrastructure to 10GbE, offering a cost-effective path to enhanced network performance and capacity without requiring a complete overhaul of fiber optic cabling.
