Build short-reach 100 GbE links with a QSFP28 optic designed for Juniper-compatible environments. The QSFP-100GBASE-SR4 COMP QSFP28 is intended for multimode fiber deployments where teams need dense port utilization, stable throughput, and a straightforward path to 100 Gigabit Ethernet connectivity. SR4 optics are a practical choice for in-rack and adjacent-rack links in modern data centers. They support the kind of high-port-count switching fabrics that depend on compact optics and disciplined cabling. For architects standardizing on 100 GbE at the access, aggregation, or leaf-spine layer, this module provides the right reach profile without moving to a longer-distance optic that adds cost and complexity. This is the kind of transceiver that earns its value in production networks: compatible, purpose-built, and aligned to short-reach multimode designs. When the goal is to keep fiber runs efficient and the switching layer dense, SR4 is the right fit.
