Whether you’re upgrading existing infrastructure or deploying a new fabric, this SFP+ transceiver offers robust compatibility, strong signal integrity, and long-term value for data centers, enterprise networks, and service provider deployments.

• High-speed 10G Ethernet over multimode fiber: This SR (Short Reach) SFP+ transceiver transmits data at 10 Gbps over multimode fiber, making it ideal for LAN uplinks, server to switch connections, and storage networking. With an 850 nm VCSEL and LC duplex connector, it supports reliable, low-latency links up to 300 meters on appropriate OM2/OM3/OM4 fiber, enabling scalable uplink bandwidth for growing networks without overhauling backbone cabling.
• Extended temperature capability for harsh environments: Built for reliability in challenging settings, the Extreme Networks 10G SR SFP+ Ext.Temp module operates across an extended temperature range. This makes it well-suited for data centers with variable cooling, outdoor facilities, or edge deployments where ambient conditions can fluctuate. The extended-temp design helps maintain link integrity and consistent performance in environments that push standard commercial components.
• MSA-compliant, hot-swappable SFP+ form factor (LC duplex): As a standardized SFP+ transceiver, it plugs into any SFP+ slot that supports 10GBASE-SR, offering broad compatibility across switches, routers, and storage switches. The LC duplex optical connector ensures a secure, low-loss fiber connection, while the hot-swappable design minimizes downtime during maintenance or upgrades. This flexibility is essential for multi-vendor networks and campus backbone deployments where interoperability matters.
• Power-efficient, reliable operation with diagnostic capabilities: The transceiver is designed for stable, long-term operation with efficient power usage and built-in diagnostics. Digital Diagnostics Monitoring (DDM/DOM) support provides real-time visibility into transmitter power, received power, temperature, and other critical parameters, helping network engineers predict failures before they disrupt services and simplify fleet management for large-scale deployments.
• Versatile use cases for data centers, virtualization, and uplinks: Ideal for top-of-rack and spine-leaf architectures, server connections, storage area networks, and campus LAN backbones, this 10G SR SFP+ Ext.Temp module offers a cost-effective, scalable solution for increasing bandwidth without re-cabling. Its multimode fiber compatibility, extended temperature resilience, and SFP+ interoperability make it a dependable choice for enterprises migrating to 10 Gigabit Ethernet, implementing virtualization, or expanding captive-wiber uplinks in hybrid cloud environments.

how to install Extreme Networks 10G SR SFP+ 300m Ext.Temp

• Power down the device or perform a standard hot-swap according to your equipment’s maintenance procedure. SFP+ modules are designed for hot-swapping in modern switches and routers, allowing for minimal downtime when upgrading uplinks or expanding capacity.
• Identify an available SFP+ slot that supports 10GBASE-SR in your switch, router, or storage switch. Confirm that the slot is compatible with LC duplex transceivers and multimode fiber.
• Handle the transceiver by its edges and avoid touching the optical connector faces. Remove the dust cap only when you are ready to install, and clean the fiber connectors prior to mating the patch cables.
• Insert the Extreme Networks 10G SR SFP+ Ext.Temp module firmly into the SFP+ slot until it seats with a click. Ensure the module is fully engaged and aligned with the slot, then re-secure any hot-swap provisions if applicable.
• Connect a clean LC-LC multimode fiber patch cord (OM2/OM3/OM4 as appropriate) between the transceiver and the target device. Verify the connector is clean and free of fibers, then power on the device or allow it to boot. Use the management interface to confirm link status and monitoring data from the transceiver.
• Check link integrity and performance. Look for a solid link LED indicator and confirm 10G link status in the device’s interface. If available, review DDM/DOM metrics to verify operating temperatures, optical power levels, and transmitter/receiver health.
• Document the change in your network inventory and label the fiber paths for future maintenance. If compatibility issues arise, consult your vendor’s interoperability guides, or verify that the transceiver’s firmware and the device’s software versions are up to date.
