Finisar SFP+ Module for 10 Gigabit Ethernet

This Intel-branded Finisar SFP+ transceiver delivers 10 Gigabit Ethernet over multi-mode fibre. It supports both 10GBase-SR/SW and 1000Base-SX protocols for flexible network deployment. The module suits data centres and enterprise switches requiring short-reach optical connectivity. It operates with a single LC connector for straightforward installation.

Single LC connector with industrial temperature

The transceiver uses a standard LC duplex interface compatible with common patch cables. Its multi-mode fibre support covers typical rack-to-rack and intra-building links. The industrial temperature range allows reliable operation in demanding equipment rooms or outdoor cabinets. A single port design keeps cabling simple and density high.

Upgrades legacy 1 Gigabit SFP links to 10 Gigabit

This module replaces older 1000Base-SX transceivers when bandwidth demands increase. The dual-rate capability protects investment by supporting both speeds on the same hardware. The jump is worth it when aggregate throughput exceeds single-gigabit capacity. Buyers needing longer reach or single-mode fibre must select a different module.

Questions about this item

What speed does the 10GBase-SR/SW interface cap at in practice?

The transceiver runs at 10 Gigabit Ethernet over multi-mode fibre, and also supports 1000Base-SX for 1 GbE links.

What fibre connector and patch-cord type does the LC port need?

It uses a single LC duplex connector, so you need a multi-mode patch cord with LC connectors on both ends.

How is the module installed and what step is often missed?

Slide the SFP+ module into the switch or router cage until it clicks, then remove the dust caps and insert the LC cables — forgetting to remove the caps blocks the link.
