Add 100G optical capacity with the Fortinet FN-TRAN-QSFP28-ER QSFP28 module. Built for data networking and optical network applications, it provides a single 100GBase-X interface for 100 Gigabit Ethernet deployments, making it a straightforward fit for high-speed uplinks and backbone connections. This module is designed for environments where longer optical reach is required than short-reach multimode optics can provide. In practice, that makes it useful for connecting aggregation switches, distribution layers, and other network segments that need dependable 100G transport across fiber infrastructure. The QSFP28 form factor keeps the module compatible with high-density switch designs, while the one-port configuration supports focused deployment in enterprise and service-provider-style network builds. A 1-year limited warranty is listed in the source data, which is typical for transceiver-class hardware and helps define the service window for procurement planning. For teams standardizing on Fortinet optics, this module offers a direct way to expand 100G capacity without changing the switching architecture. It is a practical choice when the network design calls for optical reach, port density, and predictable interoperability in a compact module.
