Dell-compatible 10G SFP+ transceiver

The AddOn N743D-AO is a hot-swappable SFP+ transceiver built for Dell networking equipment. It delivers 10 Gbps connectivity over multi-mode fibre using an 850nm wavelength and an LC duplex connector. Network engineers upgrading or expanding Dell switches can deploy it without powering down the chassis.

Fits standard SFP+ cages with LC patch cables

The module slides into any SFP+ port that accepts Dell part number N743D, so no adapter brackets or firmware tricks are required. Multi-mode fibre patch cords with LC connectors complete the link, and the hot-pluggable design lets technicians add or replace links while the switch stays live. It operates from 0 to 70 °C inside the host system.

300-metre reach on OM3 or OM4 multi-mode fibre

At 10 Gbps the transceiver reliably covers 300 metres on compliant multi-mode cable, which suits most rack-to-rack and row-to-row runs in a data centre. Longer spans or single-mode infrastructure will exceed the SR specification, so buyers planning campus links or metro distances need a different optics class.

Questions about this item

What distance limit applies when the 10GBase-SR transceiver runs continuously on multi-mode fibre?

The SR module is rated for 300 metres on OM3 or OM4 multi-mode fibre at 850 nm, so sustained traffic cannot exceed that reach without signal degradation.

What thermal load should be expected inside a switch chassis when the SFP+ module operates at 0 to 70 °C ambient?

The transceiver is specified for an operating range of 0 to 70 °C and draws power directly from the host SFP+ cage; no separate cooling is required beyond normal switch airflow.

Which host equipment must already be in place for this Dell-compatible SFP+ to function?

A Dell switch or router with an open SFP+ port that accepts 10GBase-SR optics, plus multi-mode LC patch cables, are required before the module can link.
