AddOn Networks SFP-1000BASE-SX-AO network transceiver module Fiber optic 1000 Mbit/s 850 nm

What it is

The AddOn Networks SFP-1000BASE-SX-AO is a 1 Gigabit SFP fiber transceiver module operating at 850 nm over multimode fiber. It conforms to the 1000BASE-SX standard and is designed to drop into SFP-capable switches, routers, and network equipment in place of OEM modules — at a fraction of the price.

Who it's for

Network engineers, IT managers, and AV/data installers who need a reliable, standards-compliant SFP module without paying OEM prices. It suits anyone extending or upgrading a multimode fiber backbone in a data centre, server room, or commercial building network.

Why it's good

• 1000 Mbit/s throughput — full Gigabit over multimode fiber.
• 850 nm wavelength — compatible with standard OM1, OM2, and OM3 multimode fiber patch leads.
• AddOn Networks builds these to meet or exceed OEM specs, so you get consistent performance without paying brand premium.
• At under €22 ex VAT, it's one of the most cost-effective ways to add a fiber uplink port to your switch stack.

When to choose it

Choose this module when you need a 1G multimode fiber SFP on a tight budget and your switch accepts third-party transceivers. It's not suitable for single-mode fiber runs or long-distance links — for those, you'll need a 1000BASE-LX or similar module. If your switch firmware locks out non-OEM optics, check compatibility before ordering.
