Dell PowerEdge Optical Transceivers, DAC & Active Optical Cables

Match the transceiver to the port speed and form factor, then choose the optical grade (SR for short fibre, LR for long single-mode) for the distance. Send your switch or server model and we confirm the exact Dell part.

SR (short reach) uses 850nm over multimode fibre for in-building links up to a few hundred metres; LR (long reach) uses 1310nm over single-mode fibre for runs up to 10 km.

A direct-attach copper cable with fixed connectors that uses no power and costs little, ideal for short links between a server and a top-of-rack switch in the same rack.

An AOC is used for longer or denser runs where copper twinax is too bulky, too stiff or beyond its reach, while keeping fixed plug-in ends for easy installation.

No. 100GbE is available in SR4, LR4, CWDM4 and BIDI modules with different fibre types and reaches. The correct module depends on the distance and the fibre already installed.

Genuine Dell optics are validated for Dell PowerSwitch and PowerEdge ports. For third-party hardware, confirm compatibility with that vendor; we can advise on the link before you order.

Digital diagnostic monitoring lets you read live values such as optical power, temperature and laser bias, useful for verifying and troubleshooting a fibre link.

No. They use different form factors and signalling (QSFP+ versus QSFP28). Each must match the port, although some ports support lower-speed modules depending on the device.

SR optics typically reach up to about 300 m on multimode fibre depending on the speed and OM grade; LR is used for longer distances on single-mode fibre.

Yes. We supply new genuine Dell transceivers and cables validated for the relevant ports, not unbranded copies that can fail to link or disable diagnostics.

Yes. DAC and AOC cables are offered in standard lengths such as 1, 2, 3, 5, 10 and 20 metres; choose the shortest length that routes cleanly to keep signal integrity.

Generally no; SR is for multimode and LR for single-mode. A BIDI or CWDM4 module may suit a specific installed fibre, which we confirm against the link.

Common causes are a speed or form-factor mismatch, dirty or damaged fibre, or exceeding the rated reach. We help verify the correct module and cable for the port.

Transceivers are supplied in protective packaging and cables are coiled to avoid tight bends; they can be shipped individually or consolidated with a switch or server order.
