The ONT-800 mainframe builds on its predecessor, the industry reference ONT-600, to deliver the bandwidth, power and cooling requirements for testing at 600G per lambda, and beyond. The ONT family features multiple mainframe options and compatible application modules, ranging from “single-slot” point tools up to a full 19” rack-mounted multi-slot, multi-port and multi-user solution that satisfies sophisticated SVT needs. All application modules share the same GUI, automation and scripting, for ease of use and versatility throughout product development cycles.
