Product Identity

The Allied Telesis AT-DMC1000/ST-90 is a network transceiver supporting 1000Base-T and 1000Base-X technologies. It suits administrators who need to link copper and fibre segments at gigabit speed in commercial environments. The module is supplied new and carries the Allied Telesis brand.

Compatibility Check

Verify that your switch or router provides an SFP slot compatible with 1000Base-X optics. Confirm the link partner supports 1000Base-T on copper or 1000Base-X on fibre as required. Ensure the cabling type and distance match the transceiver specifications before ordering.

Build Integration

The transceiver occupies a single SFP port and bridges copper and fibre media without an external power adapter. It frees a fixed copper port for other uses while extending reach over fibre. No additional chassis space or cooling allowance is needed beyond the host device.

Questions about this item

Does the AT-DMC1000/ST-90 ship with any cables or mounting brackets, or must I buy them separately?

The transceiver is supplied as a standalone module; patch cables and any rack-mount hardware are not included and must be purchased separately.

Should I choose the 1000Base-T or 1000Base-X variant for my fibre uplink?

This single module supports both 1000Base-T copper and 1000Base-X fibre interfaces, so no separate variant selection is required.

What does the 1000 Mbps rating mean when the transceiver is installed in a live switch?

It delivers a full-duplex Gigabit Ethernet link at 1000 Mbps over either copper or fibre, limited by the connected port speed and cable quality.
