Juniper QSFP28 100G SR4 Transceiver, 100GBASE-SR4 | QSFP Modules

Move 100 GbE traffic with a transceiver built for dense switching environments. The Juniper QSFP28 100G SR4 module is designed for short-reach optical links where multimode fiber, high port density, and consistent interoperability matter. SR4 optics are a strong fit for top-of-rack, leaf-spine, and switch interconnect deployments. The QSFP28 form factor keeps the footprint compact while supporting 100 Gbps transport, helping infrastructure teams scale bandwidth without consuming unnecessary rack space or switch ports. In practical terms, that means cleaner uplink design and fewer compromises when building high-capacity fabrics. This module is aimed at teams that need a precise fit for Juniper switching platforms rather than a generic optic with uncertain behavior. Compared with lower-cost alternatives, a specified SR4 transceiver reduces deployment risk in environments where link stability, compatibility, and operational consistency are worth more than a small upfront savings.
