Juniper Networks EX-SFP-10GE-LR SFP+ Transceiver

The Juniper Networks EX-SFP-10GE-LR SFP+ Transceiver provides 10 Gigabit Ethernet connectivity over single-mode fiber for long-range links in data centers, enterprise backbones, and telecom networks, and is commonly deployed in Juniper EX Series switches to enable scalable uplinks and inter-switch connectivity. It operates at 1310 nm over SMF, uses an LC duplex connector, and in the SFP+ form factor supports distances up to 10 km, making it suitable for inter-switch links, data center interconnects, WAN uplinks, and metro-area network extensions. This module is hot-swappable and supports Digital Diagnostics Monitoring (DDM) for real-time monitoring of optical performance and device health, helping maintain link reliability in mission-critical environments. Part numbers include MPN EX-SFP-10GE-LR, Alternate 740-031981, and OEM FTLX1471D3BNL-J1, and it is designed for Juniper EX Series switches and compatible platforms, ensuring straightforward replacement or upgrades of existing transceivers.
