Maintain high-speed east-west traffic across multimode fiber with a QSFP28 transceiver designed for 100 Gigabit Ethernet deployments. The AddOn JNP-QSFP-100G-SR4-AO uses a hot-swappable QSFP28 form factor and MPO connectivity to support 100GBase-SR4 links in data center and optical network environments. Built for short-reach interconnects, this module fits cleanly into switch-to-switch and switch-to-server architectures where port density and predictable optics matter. Multi-mode fiber support makes it a practical choice for structured cabling already in place, while the compact transceiver format helps preserve rack space and simplify field replacement. For teams standardizing on compatible optics, this module offers a straightforward path to restore or expand 100 GbE connectivity without changing the underlying platform. The lifetime warranty adds long-term procurement confidence for infrastructure teams that need dependable parts availability and consistent deployment behavior.
