JDSU ONT-503 Optical – Payload Module 40/45G 3061/91.81 AND 3075 /01

The JDSU ONT-503 Optical Payload Module is a high-speed optical network test component engineered for 40G, 43G, and 45G payload analysis. Deployed within the ONT-5xx modular test platform, this payload module delivers both unframed BER testing and framed SDH/SONET/OTN functional testing across optical and electrical interfaces. The platform integrates a 3-slot mainframe with 15-inch touchscreen, enabling portable lab and field deployment for transport network validation.
