HPE Aruba Networking 100G QSFP28 LC FR1 SMF 2km Transceiver

What it is

The HPE Aruba Networking 100G QSFP28 LC FR1 SMF 2km Transceiver (R9B63A) is a single-mode fibre optic module designed for 100 Gigabit Ethernet links. It uses a standard LC duplex connector and supports distances up to 2km over single-mode fibre using the FR1 specification.

Who it's for

Network engineers and data centre teams building or expanding high-speed 100G fibre infrastructure. It's a natural fit for HPE Aruba switching environments where guaranteed compatibility matters and downtime is not an option.

Why it's good

This is an HPE-branded module — not a third-party alternative. That means it's validated for use in Aruba and HPE switches without compatibility warnings or firmware flags. For enterprise and data centre environments, that assurance is worth paying for. The FR1 specification covers the 2km reach that most campus and inter-building fibre runs require, without stepping up to a more expensive long-range module.

When to choose it

Choose this transceiver when your HPE Aruba switches need 100G uplinks over single-mode fibre at distances up to 2km. If your runs are shorter and you're on multimode fibre, a different module will suit better — we're happy to advise.
