The VIAVI ONT-800 is a modular multi-protocol optical network test platform designed for high-speed Ethernet, OTN, coherent optics, PAM4, PCIe transport, and optical transport validation across R&D, system verification, manufacturing, hyperscale, and telecom lab environments. Highly configurable, multi-protocol, multi-port test platform for R&D and system verification of optical transport ICs, modules, and systems 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. The VIAVI 800G FLEX XPM Module is for NEMS, IC and Module Vendors who work on high speed 800G Ethernet projects. It is a Performance Validation and Debugging Test System for R&D, System Verification and Production that accelerates development projects by providing insight into lower layers. 800G is the latest generation of high-speed optical transmission used to drive high-capacity Ethernet interfaces. The addition of 800 Gigabit per second (Gbps) capability also includes options for 8 lanes ratcheted to 800 Gbps speeds, or the pairing of two 400G channels. High baud rates of 28 or. The VIAVI ONT 800G ETHERNET Module is the ideal solution for multi-port Ethernet Lab and Production applications. It provides 400G class Ethernet traffic generation with advanced Ethernet Alarm and Error testing.
