The StarTech EXSFP10GELRS is a Juniper EX-SFP-10GE-LR compatible SFP+ fiber transceiver designed, programmed and rigorously tested to work with Juniper brand switches and routers. This high-performance 10GbE SFP+ transceiver enables long-reach fiber connectivity over single-mode fiber (SMF), delivering robust, enterprise-grade 10GBASE-LR connectivity for data centers, campus networks, and mission-critical links. Whether you’re expanding your existing Juniper deployment, upgrading uplinks, or building a new infrastructure from scratch, this module offers a dependable, plug-and-play option that helps minimize downtime and maximize throughput.

• Proven Juniper Compatibility: Specifically engineered to be compatible with Juniper EX-series switches and routers, the EXSFP10GELRS module provides a seamless, drop-in replacement for the official Juniper LR transceivers. It’s designed to emulate the electrical and optical characteristics required by Juniper devices, ensuring stable operation, reliable link establishment, and consistent performance across your 10 Gigabit links.
• 10GBASE-LR over Single-Mode Fiber (SMF): This SFP+ transceiver supports 10 Gigabit Ethernet over long-reach single-mode fiber. With the 1310 nm transmit wavelength, it delivers dependable data transmission over distances up to standard LR specifications, making it ideal for data center interconnects, campus backbone links, and inter-building connections where fiber runs extend beyond short-range limits.
• Long-Distance Reach and Quality of Service: Engineered for up to several kilometers of SMF transmission, the module enables high-bandwidth links between distant network devices while maintaining low latency and strong signal integrity. Pair it with compatible SFP+ ports and fiber cabling to unlock scalable uplinks, fan-out connections, and optimized traffic engineering in your Juniper network.
• Digital Diagnostics Monitoring (DDM): The EXSFP10GELRS supports DDM, providing real-time monitoring of critical optical and electrical parameters. With DDM, network engineers can read temperature, supply voltage, optical output power, and received input power, enabling proactive maintenance, quick fault isolation, and enhanced link reliability.
• Plug-and-Play, Hot-Swap Ready: The module is designed for straightforward installation in standard SFP+ ports. It fits the familiar small form-factor pluggable (SFP+) slot, supports hot-swapping in compatible equipment, and aligns with industry-standard performance to minimize disruption during upgrades or maintenance windows.

How to install StarTech Juniper EX-SFP-10GE-LR Compatible SFP+ Module

• Power down or follow your equipment’s hot-swap procedure, then locate an available SFP+ slot on the Juniper device.
• Hold the transceiver by the body (not the connector) and align it with the SFP+ slot. Gently insert until it seats firmly and clicks into place.
• Attach a compatible SMF LC duplex fiber patch cable to the LC duplex connector on the transceiver, ensuring the correct transmit/receive orientation at both ends.
• Reconnect power and monitor the device management interface or LED indicators to verify link establishment. If the link is not immediately up, reseat the module or recheck fiber connections and fiber cleanliness.
• Access the device’s management software to confirm 10GbE operational status, and if needed, review Digital Diagnostics Monitoring (DDM) data to assess optical power, temperature, and other critical metrics for ongoing health assessment.
