## Summary description

10-pack StarTech compatible SFP transceiver modules for 1000BASE-LX networks. Fiber optic SFP interface supporting 1GbE (max 1250 Mbit/s), 1310 nm wavelength and up to 10 km reach over single-mode/multi-mode fiber. Aluminum housing, DDM support, typical power 1 W, compact SFP dimensions and MTBF ~3,092,408 h. Suited for HPE switches listed and general Gigabit Ethernet links.

## Long description

The StarTech compatible SFP Transceiver Module 1000BASE-LX 10-pack provides fiber optic connectivity for 1 GbE links using LC connectors. Designed for 1000BASE-LX networks, each compact SFP module operates at a 1310 nm wavelength and supports transmission distances up to 10 km over single-mode or compatible multi-mode fiber. The modules have an aluminum housing, support Digital Diagnostics Monitoring (DDM) and are hot-swappable to simplify maintenance and replacements in rack-mounted switches and routers.
Advantages
These transceiver modules deliver standardized 1 GbE performance with a 1250 Mbit/s signalling capability, low typical power consumption under 1 W, and a high mean time between failures for reliable long-term operation. The aluminum enclosure provides mechanical protection and thermal dissipation while DDM enables real-time monitoring of optical parameters. Supplied as a 10-pack, the modules allow bulk deployment or spare inventory to reduce downtime during swaps.
Suitable for
Gigabit Ethernet fiber uplinks between switches and routers
Long-reach connections up to 10 km over single-mode fiber
Data center and server room link aggregation or redundancy
Replacing or expanding SFP ports on compatible network equipment
Key specifications
Interface type: SFP (small form-factor pluggable)
Maximum data transfer rate: 1250 Mbit/s (1.25 Gbps)
Wavelength: 1310 nm
Optical reach: up to 10 km over single-mode or compatible multi-mode fiber
Connector: LC duplex
Housing material: aluminum
Digital Diagnostics Monitoring (DDM): supported
Typical power consumption: \< 1 W per module
Form factor: hot-swappable SFP
Weight (pack): approximately 0.171 kg
How to use
Insert each SFP module into a compatible SFP slot on the switch or router until it latches; avoid excessive force. Connect LC fiber patch cables to the module’s duplex LC connectors, ensuring correct transmit/receive orientation. After insertion and fiber connection, confirm link status on the network device and monitor DDM values to verify optical power and temperature parameters. To remove, disengage any retention mechanism and gently pull the module straight out while observing ESD precautions.
Usage recommendations
Use single-mode fiber for maximum reach to 10 km; verify compatibility with your network equipment firmware before large-scale deployment. Keep spare modules on hand for rapid replacement, and routinely check DDM readings to detect signal degradation early.
