About This Part
The Juniper Networks Part Number 740-057909 is a high-performance 10 Gigabit Ethernet SFP+ (Small Form-Factor Pluggable Plus) Long Reach (LR) optical transceiver module. This component is engineered for robust, high-speed data transmission over single-mode fiber (SMF) infrastructure. Operating at a wavelength of 1310nm, it facilitates reliable 10Gbps connectivity, adhering to industry-standard Ethernet protocols. As an SFP+ form factor module, it ensures compatibility with a wide range of network equipment designed for 10 Gigabit Ethernet. Its primary function is to provide extended reach, typically up to 10 kilometers, making it suitable for interconnecting network devices across significant distances within a data center, campus, or metropolitan area network. This module represents a critical interface for high-bandwidth network architectures. This Juniper Networks transceiver is typically deployed in Juniper Networks SRX Series firewalls, routers, and switches that feature SFP+ ports, serving as a vital link in high-capacity network segments. Its use cases span across data center interconnects, enterprise campus backbones, and service provider access networks, where reliable long-distance 10GE connectivity is paramount. Telecom operators, cloud service providers, and large enterprises leverage this module to establish or upgrade their network infrastructure, solving the challenge of transmitting high volumes of data over single-mode fiber without signal degradation. It serves as an essential upgrade path from slower 1Gbps connections or as a replacement for shorter-reach multi-mode fiber solutions, enabling the robust and scalable network performance required in modern IT environments.
