Gigabit fiber converter card module

The StarTech.com ET91000SFP2C is a card-style media converter that bridges a 1000BASE-T copper link to a fiber segment using any compatible Gigabit SFP module. It suits network engineers who need to extend Ethernet beyond copper distance limits inside a managed chassis environment.

Open SFP slot with chassis mounting

The module presents one RJ-45 port and one open SFP cage, accepting the transceiver that matches the required fiber type and reach. Its card form factor slides into a StarTech.com media converter chassis for high-density rack deployments, while link-loss forwarding and remote status monitoring help maintain visibility across the link. An external 12 V DC supply rated at 1 A is required but not included.

Upgrade from fixed-transceiver converters

This unit replaces single-purpose fiber converters by letting you select or change the SFP as network requirements evolve. The jump is worthwhile when you manage multiple fiber runs with differing distances or connector types and want a single spare module type to cover them all.

Questions about this item

Which Ethernet standards does the ET91000SFP2C support and what speed do they cap at?

It supports IEEE 802.3ab 1000BASE-T, 802.3u 100BASE-LX and 802.3z 1000BASE-SX, all running at 1.25 Gbps through the RJ-45 and SFP ports.

What are the exact dimensions and weight so I can confirm it fits my chassis slot?

The module measures 5.6"L x 2.9"W x .8"H and weighs 112 g (4 oz), matching a standard card-module form factor.

How do I install the SFP transceiver and what step is often missed?

Insert your chosen Gigabit SFP into the open slot until it clicks, connect fiber and copper cables, then apply 12 V DC power — the converter ships without a power adapter, so you must supply one.
