Juniper QSFP28 100GBASE-LR4 Optics | 100G, QSFP28, Enterprise

Keep 100G transport stable across single-mode fiber with a transceiver built for serious network infrastructure. The Juniper QSFP28 100GBASE-LR4 optics module is designed for optical networking and data networking applications where long-reach connectivity, consistent signaling, and platform fit are non-negotiable. This QSFP28 module supports 100 Gigabit Ethernet and is intended for Juniper QFX10000 Modular Ethernet Switches, giving teams a clear deployment path in core, aggregation, and high-capacity transport roles. Its single-port design keeps the footprint compact while preserving the optical characteristics needed for dependable backbone links. Compared with lower-speed optics, LR4-class modules are chosen when distance and link stability matter more than minimizing upfront cost. That makes this module a practical fit for enterprise cores, campus backbones, and data center interconnects where replacing optics later is more expensive than specifying the right part now. For teams standardizing on Juniper, this module supports a controlled, predictable optics strategy across critical infrastructure.
