AddOn Networks 1000BSX SFP SMF 1310nm 10km network transceiver module Fiber optic 1000 Mbit/s

What it is

The AddOn Networks MGBLX1-AO is a 1000BASE-SX SFP transceiver module designed for single-mode fibre (SMF) at a 1310nm wavelength, with a reach of up to 10km. It delivers Gigabit Ethernet (1000 Mbit/s) connectivity in a compact, hot-swappable SFP form factor.

Who it's for

This module suits network engineers, IT managers, and AV installers who need to extend a Gigabit fibre link up to 10km — typically between buildings, across a campus, or within a data centre where longer runs are required. It's a cost-effective replacement or expansion module for switches and routers with SFP slots.

Why it's good

• Runs on single-mode fibre at 1310nm — the standard for reliable longer-distance links up to 10km.
• Full Gigabit (1000 Mbit/s) throughput keeps bandwidth consistent across the link.
• Hot-swappable SFP form factor means you can install or replace it without powering down your switch.
• AddOn Networks modules are tested for compatibility with major switch brands — reducing the risk of interop issues.
• Priced competitively at under €26 ex VAT — a practical choice when you need a spare or a budget-conscious deployment.

When to choose it

Choose this module when you have a single-mode fibre run of up to 10km and need a dependable, affordable Gigabit SFP to fill an empty slot. If your run is under 550m and you're using multi-mode fibre, a standard 1000BASE-SX module would suit better. For distances beyond 10km, look at 1000BASE-LX or LH variants instead.
