Question 1

What is a Dell Networking Compatible QSFP+ module?

Accepted Answer

A Dell Networking Compatible QSFP+ module is a quad small form-factor pluggable transceiver designed for high-speed 40 GbE interconnects, fully compliant with Dell switch hardware and firmware.

Question 2

What data rates do Dell Networking Compatible QSFP+ modules support?

Accepted Answer

Dell Networking Compatible QSFP+ modules support up to 40 Gbps full-duplex data rates, enabling aggregated high-speed links and low-latency network performance.

Question 3

Which fiber types are supported by Dell Networking Compatible QSFP+?

Accepted Answer

Dell Networking Compatible QSFP+ modules are available in both multimode (OM3/OM4) and single-mode (SMF) variants to suit short-reach and long-reach applications up to 10 km.

Question 4

Are Dell Networking Compatible QSFP+ modules hot-swappable?

Accepted Answer

Yes. Dell Networking Compatible QSFP+ modules are hot-swappable, allowing live insertion and removal without powering down the switch or disrupting traffic.

Question 5

How do I verify compatibility with my Dell switch?

Accepted Answer

Check the Dell Networking Technical Guide or use the Dell Support site to match the module’s part number against your switch model and firmware version.

Question 6

Can I use Dell Networking Compatible QSFP+ modules in non-Dell switches?

Accepted Answer

Dell Networking Compatible QSFP+ modules may interoperate with other vendor equipment if the switch accepts standard QSFP+ MSA signatures; however, full compatibility is guaranteed only on Dell hardware.

Question 7

What wavelengths do Dell Networking Compatible QSFP+ modules use?

Accepted Answer

Multimode QSFP+ modules typically operate at 850 nm, while single-mode variants use 1310 nm or 1550 nm wavelengths for extended reach.

Question 8

What distances can I achieve with Dell Networking Compatible QSFP+?

Accepted Answer

Om3 OM4 multimode modules support up to 150 m and 400 m respectively, while single-mode modules cover 2 km, 10 km, 40 km, and beyond, depending on the model.

Question 9

How do I install a Dell Networking Compatible QSFP+ module?

Accepted Answer

Align the module ejector lever, insert the transceiver into the QSFP+ port until it clicks, then secure the fiber cable and verify link status via switch CLI or GUI.

Question 10

What is the typical power consumption of a QSFP+ module?

Accepted Answer

Dell Networking Compatible QSFP+ modules consume between 1.5 W and 3.5 W per module, depending on reach capability and laser technology.

Question 11

How do I troubleshoot link issues with QSFP+ modules?

Accepted Answer

Confirm proper insertion, inspect fiber cleanliness, verify switch diagnostics for module status, and update firmware or replace the module if errors persist.

Question 12

Do Dell Networking Compatible QSFP+ modules carry a warranty?

Accepted Answer

Yes. All Dell Networking Compatible QSFP+ transceivers include a limited lifetime warranty when used on supported Dell platforms.

Question 13

Are these modules compliant with industry standards?

Accepted Answer

Dell Networking Compatible QSFP+ modules adhere to IEEE 802.3ba/802.3bm specifications and the SFF-8436 QDR QSFP+ multi-source agreement.

Question 14

Can I stack multiple QSFP+ ports for 100 GbE links?

Accepted Answer

Yes. By using breakout cables or port stacking, four 25 GbE lanes in a single QSFP+ can form an aggregated 100 GbE connection.

Question 15

What breakout cable options exist for QSFP+ ports?

Accepted Answer

Dell supports 1 × 4 SFP+ and 2 × 10 GbE breakout cables, enabling flexible port-density optimization from a single 40 GbE QSFP+ port.

Question 16

How do I ensure optimal performance with Dell QSFP+?

Accepted Answer

Use certified fiber cabling, maintain proper transceiver firmware, monitor link diagnostics, and replace modules at the first sign of degraded optical power or errors.
