Lenovo QSFP28 100 Gigabit Ethernet Transceiver Module

The Lenovo 4M27A67042 is a QSFP28 transceiver module that brings a reliable 100 Gigabit Ethernet connection to Lenovo networking and storage systems. Built for short-reach optical fiber links, it uses 100GBase-SR4 technology to move data at up to 100 Gbps over distances of up to 328 feet. That speed keeps traffic flowing smoothly between servers, top-of-rack switches, and storage arrays inside a modern data center.

Installation is straightforward. The module slides into any compatible QSFP28 port and immediately begins passing traffic, so network teams can upgrade bandwidth without long maintenance windows. Because Lenovo has qualified it for ThinkSystem Mellanox ConnectX-6 HDR InfiniBand adapters as well as DM7100F and DM7100H 4U storage chassis, you can deploy it with confidence that firmware and optics have already been tested together.

In everyday use, this transceiver helps consolidate multiple 10 GbE or 25 GbE links into a single high-capacity uplink, cutting cable clutter and simplifying switch configurations. It is equally at home feeding bandwidth-hungry virtualized servers, carrying storage replication traffic, or connecting nodes in a high-performance computing cluster where low latency and consistent throughput matter.

For data center managers who need dependable performance, simple deployment, and assured compatibility inside Lenovo environments, this module offers an easy path to 100 Gigabit speeds without overcomplicating the network.
