Open SFP Slot Media Converter

The StarTech ET91000SFP2 converts a copper Gigabit Ethernet link to fibre using any MSA-compliant SFP module you supply. It suits installers who need to bridge buildings or extend a network beyond the 100-metre copper limit without committing to a fixed transceiver.

Sustained Load Behaviour

The converter handles a continuous 1.25 Gbps transfer rate across its RJ-45 and SFP ports while drawing up to 8 W from the included universal AC adapter. Operating temperature is rated 0 to 60 °C and humidity tolerance reaches 90 % non-condensing, so the unit remains stable in warm equipment cabinets during long-term operation.

Upgrade Path and Fit

This model replaces fixed-transceiver converters such as the ET91000LC2 by letting you choose single-mode or multi-mode fibre per link. The jump is worthwhile when you need flexibility to change reach or fibre type later, but it is not for buyers who want a pre-installed SFP or a managed switch with multiple ports.

Questions about this item

How much heat does the 8-watt converter add to a rack that runs 24/7?

The unit draws 8 watts from its 12 V DC supply and is rated for continuous operation at up to 60 °C ambient, so it adds minimal heat to a cooled cabinet.

What SFP module do I need to make the RJ-45 and fiber ports talk to each other?

Any MSA-compliant Gigabit SFP — 1000BASE-SX, 1000BASE-LX or 100BASE-LX — plugs into the open slot and sets the fiber type and reach.

Will the RJ-45 port link at 1000 Mbps with my older 100 Mbps switch?

The copper port follows IEEE 802.3ab for 1000BASE-T; it will negotiate down to 100 Mbps if the connected switch only supports Fast Ethernet.
