HPE TRANSCEPTOR 100GB QSFP28 MPO SR4 100

In high-density data centers where every watt and rack unit counts, network engineers deploy the HPE 100G QSFP28 MPO SR4 Transceiver to link top-of-rack switches to aggregation layers over short multimode fiber runs. This plug-in module delivers 100 Gigabit Ethernet over four parallel 25G channels, using an MPO-12 connector and 850 nm VCSEL array to push data up to 100 meters on OM4 fiber. It is fully compliant with IEEE 802.3bm 100GBASE-SR4 and supports digital diagnostics monitoring for real-time link health checks. Hot-swappable and drawing under 3.5 W, it is a practical choice for Aruba switch environments that demand reliable, low-latency connectivity without complex configuration.

Why choose it

This transceiver eliminates the cost and complexity of single-mode optics for short-reach 100G links. Its low power draw reduces cooling load, while DDM gives you visibility into optical power, temperature, and voltage—simplifying troubleshooting. Because it is hot-swappable, you can replace or upgrade modules without downtime, keeping your fabric resilient.

Ideal use cases

• Data center spine-leaf interconnects within a rack or row
• High-performance computing clusters needing 100G server-to-switch links
• Enterprise campus aggregation over pre-installed OM4 multimode fiber
• Lab or test environments validating 100GBASE-SR4 equipment

Good to know

Pair this module with OM4 laser-optimized multimode fiber for the full 100 m reach; OM3 is supported but limited to 70 m. The MPO connector requires proper polarity and cleaning—use an MPO inspection scope before mating. While designed for HPE Aruba switches, it follows MSA specifications, so it may work in other QSFP28 ports that accept SR4 optics, but always check your vendor's compatibility matrix. Keep spare modules on hand: the hot-swap capability means a quick swap can restore a link in seconds.
