Compatible with major switch brands — share your equipment model to confirm coding before ordering. 3-year warranty included.
The 100GBASE-SR4 QSFP28 transceiver delivers 100 Gbps over multimode fiber (MMF) through an MPO interface, up to 100 m. It is hot-pluggable, QSFP28 MSA-compliant, and supports DDM digital diagnostics.
100G QSFP28 is the standard spine-leaf fabric speed: leaf uplinks, storage fabrics and metro 100G transport. SR4 uses MPO multimode to 100 m; LR1, ER4 and ZR4 cover 10–80 km over single-mode LC for campus and metro spans.
MPO links are polarity-sensitive: confirm the MPO polarity and fiber count match your patch panel before installation, and clean both end faces. Share your switch model and port type so we confirm the coding for your equipment; every module ships with a 3-year warranty and free technical support.
