  • Low power draw under 3.5 W from single 3.3 V supply

100G QSFP28 Active Optical Cable

The LR-LINK QSFP28-AOC-5M is a 5 metre active optical cable designed for 100Gb or 40Gb Ethernet links. It uses four full-duplex channels, each operating up to 25Gbit/s, to deliver aggregate 100G throughput. The cable draws under 3.5W from a single 3.3V supply and conforms to the IEEE 802.3 bm standard.

Suited for short-range rack interconnects

This cable suits data-centre operators who need a lightweight, low-power alternative to direct-attach copper for intra-rack 100G links. It is not for buyers who require longer reach beyond the 5 metre length, nor for installations that demand industrial-grade temperature tolerance down to -20°C or up to +85°C.

Hot-pluggable QSFP28 installation

The QSFP28 form factor is hot-pluggable, so the cable can be inserted or removed without powering down the switch or NIC. No driver or firmware configuration is required on the host side. The most common issue is mismatched port speed settings — both ends must be configured for 100G or 40G operation to establish a link.

Questions about this item

What ports must my switches or network cards have to use this QSFP28-AOC-5M cable?

Both ends need QSFP28 ports that support 100G or 40G Ethernet over four 25Gbit/s channels.

Can I connect this 100G active optical cable directly to a 40G QSFP+ port on older equipment?

The cable follows the 100G Ethernet IEEE 802.3 bm standard and is built for 100G or 40G Ethernet links; compatibility depends on the host port accepting a QSFP28 module at those speeds.

How can I verify the LR-LINK QSFP28-AOC-5M is operating correctly after installation?

Confirm the link comes up at 100Gb/s or 40Gb/s, check that each of the four channels runs at up to 25Gbit/s, and ensure power draw stays below 3.5W.
