Juniper QSFP28-DD QDD-2X100G-SR4 2x100G SR4 Transceiver | QSFP28-DD, Enterprise

Reduce cabling complexity while preserving the short-reach performance your fabric depends on. Juniper QDD-2X100G-SR4 is a QSFP28-DD SR4 transceiver designed to carry 2 x 100G over multimode fiber, making it a strong fit for leaf-spine environments, top-of-rack aggregation, and dense switch deployments where port efficiency matters. This module is aimed at infrastructure teams that need to scale bandwidth without overcommitting to longer-reach optics or unnecessary cost. The QSFP28-DD form factor supports high-density designs, while the SR4 optical profile keeps it aligned to short-distance interconnects inside the data center. For architects standardizing on Juniper optics, it offers a clean path to higher aggregate throughput with fewer modules and less front-panel congestion. Choose this transceiver when the priority is compact, short-reach connectivity across multimode links and a deployment model that keeps optics matched to the job. It is the kind of component that earns its place in production by simplifying the physical layer while supporting demanding east-west traffic patterns.
