Two 10 Gbps SFP+ multi-mode transceivers with duplex LC connectors for fibre links up to 300 metres
This two-pack supplies 10 Gbps SFP+ optical modules built for multi-mode fibre links. Each transceiver uses a duplex LC connector and operates at an 850 nm wavelength. The pair suits network administrators extending 10 GbE connections across campus or data-centre rows up to 300 m.
Modules insert directly into any SFP+ cage that accepts multi-mode optics; no tools are required beyond standard fibre patch cables. The only common issue is mismatching single-mode cabling or exceeding the 300 m reach, which causes link failures. Remember the Class 1 laser warning: never look into the port or cable ends while powered.
Confirm that your switch or router ports support SFP+ multi-mode optics at 10 Gbps and that the existing cabling is OM3 or OM4 multi-mode fibre with LC terminations. Check that the operating temperature range of 0 to 70 °C matches the installation environment. Fibre cables are not included in the pack.

Check the link status LEDs on your switch or router; a solid green light on the corresponding port confirms the 10 Gbps link is up. The transceiver draws up to 0.8 W and runs between 0 and 70 °C, so normal warmth is expected.
The box contains two SFP+ modules with duplex LC connectors and black latches. Multi-mode fibre patch cables are not included and must be bought separately to complete the link.
This 850 nm multi-mode model is specified for up to 300 m on OM3 or OM4 fibre. Ensure your patch cables match the LC duplex interface and the required fibre grade for the distance.
