10GBASE-SR SFP+ Transceiver

This Dell 331-5311 module adds a single 10 Gbps Ethernet port to a compatible switch or server. It uses an SFP+ form factor with dual LC connectors for multi-mode fibre. The transceiver operates at 850 nm wavelength.

Ideal for short-reach links

Suits data-centre racks or campus LANs where the fibre run stays within 300 metres. Buyers who need longer distances or single-mode cabling should look at a different transceiver type.

300-metre reach on multi-mode fibre

The 850 nm optics are rated for 300 metres over OM3 multi-mode fibre, which also equals 1310 feet. This distance limit is the key specification that decides whether the module fits the planned link.

Questions about this item

What comes in the box with the 331-5311 transceiver and do I need to buy cables separately?

The module is supplied as a single SFP+ transceiver. LC duplex multimode fibre patch cables are not included and must be purchased separately to complete the link.

How do I choose between different reach options for 10 GbE SR?

This model is fixed at 850 nm wavelength with a 300 m maximum reach on OM3 multimode fibre. Select it when your link distance falls within that range.

What does the 10 Gbps rating mean when the module is installed in a switch?

The port will negotiate a 10 Gigabit Ethernet link over duplex LC multimode fibre, delivering up to 10 Gbps line rate at 850 nm across distances up to 300 m.
