Zyxel SFP-SX-D 1000BASE-SX SFP Transceiver
1000BASE-SXMultimode 850nmLC, up to 550mDDMI
The Zyxel SFP-SX-D (91-010-204001B) is a 1000BASE-SX SFP (mini-GBIC) transceiver module that adds a Gigabit fibre-optic link to a switch's SFP slot over multimode fibre. Using an 850nm laser and an LC duplex connector, it reaches up to 550m on OM2 (50µm) fibre and includes DDMI for real-time monitoring of temperature, voltage and optical power. It is the ideal way to connect switches or extend a Gigabit link beyond the 100m limit of copper. Typically in stock with fast delivery across Cyprus.
Compatibility: Plugs into a Gigabit SFP slot on a switch or media converter — designed for Zyxel SFP-capable switches and, as an SFP-MSA / IEEE 802.3z compliant module, compatible with many other vendors' SFP slots. It requires multimode fibre (OM1/OM2) with LC duplex connectors and a matching 1000BASE-SX device at the other end. It is a 1G SFP module (not 10G SFP+), and multimode-only — do not pair it with single-mode fibre or long-reach (LX/LH) modules.
Key Features
Gigabit Fibre over Multimode
1000BASE-SX at 850nm delivers a full Gigabit Ethernet link over affordable multimode fibre, ideal inside buildings and across campuses.
Reach up to 550m
Spans up to 550m on OM2 (50µm) or around 220m on OM1 (62.5µm) fibre — far beyond the 100m limit of copper Ethernet.
DDMI Monitoring
Digital Diagnostic Monitoring (SFF-8472) reports live temperature, voltage and optical power so you can track link health and troubleshoot faster.

Frequently Asked Questions
Singular Expert Insight
An 1000BASE-SX SFP like the SFP-SX-D is the standard, cost-effective way to run Gigabit fibre between switches over multimode cabling — perfect for building-to-building or floor-to-floor links that exceed copper's 100m reach. Being Zyxel-branded it is the safe choice for Zyxel switches; fit one at each end of the fibre and connect them to your network switches. For longer distances over single-mode fibre, choose a 1000BASE-LX module instead.
Buyer’s Guide
Buy it if
You need to add a Gigabit fibre uplink to an SFP-capable switch over multimode cabling, up to 550m, ideally on Zyxel gear.
Skip it if
You need single-mode long-reach fibre, a 10G SFP+ link, or a direct copper connection — this multimode 1G module will not fit those.
Also consider
A 1000BASE-LX SFP for single-mode long runs, a 10G SFP+ module for 10G links, or a DAC cable for short copper runs.
