## Long description

Extralink EX.35900 SFP+ module is a 10Gbps optical transceiver designed for single-mode fiber links. It uses an LC/UPC connector and transmits at 1310 nm, supporting distances up to 10 km. The module supports Digital Optical Monitoring (DOM) to report real-time parameters such as optical power and temperature, and is supplied as a 2-pack for deployment of matched high‑speed links in data centers, telecommunications networks and enterprise infrastructure.
Advantages
The module offers 10Gbps throughput with single-mode fiber compatibility and an LC/UPC interface, enabling reliable long-reach connections up to 10 km. Integrated DOM provides continuous monitoring of optical signal and module status, which helps with diagnostics and link management. Supplied as a two-unit set, the modules simplify procurement for paired link endpoints and reduce compatibility checks during installation.
Suitable for
 10 Gigabit Ethernet uplinks between switches and routers
 Longer distance fiber links in data centers and server rooms
 Telecom and carrier access networks requiring single-mode transceivers
 Enterprise backbone and aggregation links
Key specifications
 Data rate: 10 Gbps
 Fiber type: single-mode
 Wavelength: 1310 nm
 Connector type: LC/UPC
 Maximum reach: up to 10 km
 Monitoring: Digital Optical Monitoring (DOM)
 Form factor: SFP+
How to use
Install the SFP+ module into the SFP+ slot of a compatible switch, router or transceiver port, ensuring proper orientation and a secure mechanical connection. Connect single-mode fiber cable terminated with LC/UPC connectors to the module. Verify link status through the device's management interface and check DOM parameters to confirm optical power and module health. If necessary, configure the host device for 10Gbps operation and ensure matching duplex and speed settings on the far-end port.
Usage recommendations
Use clean LC/UPC connectors and inspect fibers before insertion to prevent signal loss. Keep SFP+ modules in protective dust caps when not installed. Match fiber type and connector polarity across the link and confirm DOM readings after installation to ensure stable performance.
