The VIAVI XPERTrak PON Port Mapper is a non‑disruptive splitter port mapping tool that prevents unnecessary customer disconnects and costly truck rolls. Technicians often arrive at splitter cabinets expecting open ports, only to find them all occupied, leading some to disconnect an existing drop and risk interrupting active service. The Port Mapper quickly identifies which splitter ports are truly available, allowing techs to add new customers confidently without affecting current subscribers. This improves workflow efficiency, protects service continuity, and eliminates guesswork in the field.
