Our take on the Dell Q28-100G-SR4-G2 100Gb/s 100GBase-SR4 Multi-Mode Fibre QSFP28 Transceiver Module

The Dell Q28-100G-SR4-G2 is a 100Gb/s QSFP28 transceiver for short-reach links over multimode fiber. It uses an 850nm VCSEL array and an MPO-12 connector, sending four 25Gb/s lanes over up to 70m of OM3 or 100m of OM4 cable. It is a plug-and-play Dell-coded module for switches, servers and storage, and it competes with generic 100GBase-SR4 optics on reach and coding rather than features. Buyers pick it for guaranteed Dell compatibility and easy MPO cabling in racks and data halls.

Questions and answers

What fiber and connector does it need?
It uses multimode fiber with an MPO-12 (MTP) connector. OM3 supports up to 70m and OM4 up to 100m.
Will it work in any 100G QSFP28 port?
It is coded for Dell equipment, so it works in Dell QSFP28 ports. In other brands it may be rejected or need coding.
Does it work in a 40G QSFP+ port?
No. It is a 100G QSFP28 module and needs a 100G-capable port; 40G ports take 40GBase-SR4 optics.
Can I use it over single-mode fiber?
No. It is an SR4 multimode module; single-mode links need a different 100G optic such as 100GBase-LR4.
What is in the box?
The transceiver module only. MPO fiber cables and patch panels are sold separately.
