Axiom DEM-330R-AX SFP transceiver

The Axiom DEM-330R-AX is a single-mode SFP module built for Gigabit Ethernet links. It uses a 1000BASE-BX-U bidirectional interface over one LC connector. Network engineers deploy it to extend fibre runs between compatible switches and routers.

Sustained link behaviour

The module maintains a steady 1000BASE-BX-U signal across the full single-mode fibre path. It operates within MSA-compliant power and temperature envelopes so throughput does not degrade during continuous traffic. RoHS-compliant components keep thermal output stable under load.

Installation notes

Insert the transceiver into any MSA-standard SFP cage until it clicks, then seat the LC patch cord. The pre-coded EEPROM identifies the module to D-Link and other OEM gear without manual configuration. A mismatched BX-D counterpart or a multi-mode patch cord will prevent the link from coming up.

Questions about this item

How much heat does the DEM-330R-AX generate when running continuously?

The module is RoHS compliant and designed for low-power single-mode operation, so heat output stays minimal during all-day use.

What must my switch provide for this transceiver to operate?

An MSA-compliant SFP cage with an LC duplex port and support for 1000BASE-BX-U single-mode fibre at the matching upstream wavelength.

Will the DEM-330R-AX link with an older 1000BASE-BX-D module on the other end?

Yes, the upstream BX-U wavelength pairs with a downstream BX-D device to form a complete bi-directional Gigabit link over one fibre strand.
