Reality: Fiber is immune to EMI, but it is fragile and expensive to terminate in the field. WUNF 426 allows copper-based field repairs with standard RJ45 tools. Furthermore, fiber requires active converters at every endpoint, whereas WUNF 426 devices can be powered over the same copper cable (PoE-426, a variant providing 90W per port).

Treating "wunf 426" as an opaque identifier, the general approach is the same: discover what it denotes, assess its scope/impact, document it, test it where applicable, and operationalize its use. Reality: Fiber is immune to EMI, but it
