Lenovo 100GBASE-SR4 QSFP28 Transceiver 7G17A03539 | QSFP Module

Move 100 GbE traffic efficiently across short-reach optical links with the Lenovo DCG Server Options 100GBASE-SR4 QSFP28 transceiver. Designed for multimode fiber, this module is suited to data center environments where high port density and short optical runs are the norm. The QSFP28 form factor keeps the footprint compact while supporting the bandwidth required for leaf-spine fabrics, top-of-rack switching, and server aggregation. SR4 optics are commonly chosen when you want to maximize throughput inside the rack row without paying for longer-reach optics you do not need. That makes this transceiver a sensible choice for teams balancing performance, port density, and budget discipline. For Lenovo infrastructure deployments, this module helps standardize 100 GbE connectivity across compatible platforms. It is built for environments that value predictable short-reach performance, straightforward optical design, and efficient use of switch real estate.
