Aruba-Compatible 1000BASE-SX SFP Transceiver

This SFP module delivers 1 Gbps over multi-mode fibre at an 850 nm wavelength. It is built for network operators who need a drop-in replacement for Aruba Networks Q8N53A equipment. The transceiver uses an LC duplex connector and reaches 550 m on standard multi-mode cable. It suits campus LAN uplinks and data-centre cross-connects where short-range fibre links are required.

Commercial-Temperature Operation 0 to 70 °C

The unit runs from 0 to 70 °C without active cooling, so it stays silent in fanless switch chassis. Power draw is low enough for dense line-card deployments and the module complies with MSA mechanical and electrical specifications. Front-panel LEDs show power, link activity, full-duplex status and speed for quick visual verification. No digital optical monitoring is implemented on this model.

Upgrade from Copper Uplinks or Shorter-Range Optics

Replacing 1000BASE-T copper links with this fibre module removes the 100 m distance limit and eliminates EMI concerns in electrically noisy environments. The jump is worth it when link runs exceed copper reach or when building-to-building paths require galvanic isolation. It does not suit single-mode fibre runs or applications needing 10 Gbps throughput.

Questions about this item

How do I install the LC duplex connector on the Q8N53A, and what is the common mistake?

Align the LC duplex connector key with the SFP port slot, insert until it clicks, then secure the bail latch; the step often missed is fully engaging the latch before cabling.

What maintenance or replacement will the Q8N53A need over time?

No scheduled maintenance is required; replace the module only if link errors appear or the 850nm optical output degrades beyond the 550m reach specification.

What limit appears first when the Q8N53A runs continuously at full load?

The commercial temperature ceiling of 70°C is the first sustained-use limit; ensure adequate airflow so the transceiver stays within the 0–70°C operating range.
