Network transceiver for multimode fibre, designed to deliver stable 1G links in enterprise and small-business networks. Network administrators gain reassurance from plug-and-play modules and broad vendor compatibility. Is 10Gtek 1G SFP SX Transceiver the sensible spare to keep in a rack?
⚡ At a Glance
- • Data Rate: 1.25Gb/s throughput, suitable for 1G SFP ports and compatible 10G SFP+ ports that support 1G
- • Best for: Network administrators and small businesses needing reliable multimode fibre links
- • Not ideal for: Environments that require compatibility with HP, Arista, Mellanox, Dell Force10, Juniper and similar vendors
1G SFP SX multimode transceiver engineered for stable gigabit links over multimode fibre. Broad vendor support covers many mainstream switches and NAS devices, while several enterprise brands are explicitly unsupported.
Quick, straightforward installation – With standard LC connector and 1G SFP form factor
Standard LC duplex connectors and the industry 1G SFP form factor match common switch ports, allowing straightforward insertion and immediate link negotiation in supported ports. User feedback highlights plug-and-play behaviour when used in compatible interfaces.
Fast deployment reduces on-site labour for upgrades or repairs, making the modules practical spares for racks and patch panels.
Reliable multimode links – With 850 nm operation and OM2/OM3/OM4 support
Operation at 850 nm is the norm for multimode applications, and compatibility with OM2, OM3 and OM4 fibre supports longer intra-site spans. The specification allows sustained gigabit signalling over typical campus and building backbones.
Consistent throughput across short and medium multimode runs keeps network services stable for servers and NAS devices on the same campus.
Maintenance-ready kit – With two modules per pack for spares and redundancy
Supplied as a pair, the modules let teams stage an immediate replacement on hand or provision redundancy across two links. Having a second unit removes the need to interrupt operations while sourcing a replacement.
Keeping one module as a ready spare limits downtime and speeds recovery when a transceiver fails or requires swapping.

❓ Frequently Asked Questions
Q: Can these modules be used in 10G SFP+ ports?
A: Yes, use in 10G SFP+ ports is possible only when those ports explicitly support 1G operation; otherwise fit into standard 1G SFP ports.
Q: What fibre types and distances are supported?
A: Dual LC multimode fibre on OM2, OM3 and OM4 is supported, with reach up to 550 m at 850 nm.
Q: Which vendors are supported and which are not?
A: Compatible vendors include Cisco, Meraki, Ubiquiti, Netgear and many NAS vendors; the modules are not compatible with HP-ProCurve, HP-H3C, HP-Aruba, Intel, Arista, Mellanox, Dell Force10, Extreme, Brocade or Juniper.
🏆 Our Verdict
Ideal for network administrators and small IT teams who need reliable, easy-to-deploy multimode SFP spares. The two-pack format, straightforward installation, and responsive manufacturer support make maintenance and rapid replacement simpler. Cost-conscious teams gain long-term value from reduced downtime and ready spares kept in the rack.
