Lenovo DM Series 100GB Transceiver 4M27A67042 | QSFP28 Module

Maintain 100 GbE connectivity in storage and data networking environments with the Lenovo DM Series 100GB Transceiver. Built as a QSFP28 module, it is designed for optical fiber deployments where short-reach performance, compact port usage, and compatibility with Lenovo ThinkSystem DM7100H Unified Hybrid Storage Array matter. The 100GBase-SR4 interface is well suited to high-density infrastructure that depends on predictable throughput between switches, storage systems, and adjacent network cabinets. By using a QSFP28 footprint, the module helps preserve port density while supporting the bandwidth required for modern storage fabrics and application traffic. This is the kind of transceiver you choose when the link budget is already defined and the priority is clean integration, consistent 100 GbE signaling, and a form factor that fits enterprise hardware without wasting rack space. It is a focused component for teams that want the right optics for the job, not excess reach they will never use.
