HP S3N89A 100G QSFP28 LR 10 km SFP transceiver

Aruba 100G QSFP28 LR transceiver

This Aruba S3N89A is a 100G QSFP28 LR transceiver built for optical and data networking. It connects via a single LC interface using single-mode fibre. The module delivers 100 Gigabit Ethernet over distances up to 10 km. It suits network engineers extending high-speed links between sites.

Steady 100 Gbit/s over 10 km single-mode fibre

The transceiver maintains a constant 100 Gbit/s line rate across the full 10 km reach. Single-mode fibre ensures low attenuation and stable signal quality during continuous operation. No burst-only behaviour is specified. The LC duplex connector provides a reliable physical link for sustained throughput.

10 km 100GBase-LR reach decides fit

The 10 km maximum distance under the 100GBase-LR standard is the key parameter for deployment planning. Links shorter or longer than this range require different optics. The LC single-mode interface and QSFP28 form factor are fixed. Buyers needing longer reach or multimode compatibility must select another module.
