The JDS Uniphase ONT-506/512 is a modular optical network tester engineered for design verification and maintenance of advanced optical transport systems at rates up to 40/43 Gb/s. Built in two form factors—a 6-slot desktop mainframe with integrated 15″ TFT display (ONT-506) and a 12-slot rack-mount chassis (ONT-512)—this platform delivers multi-port, multi-application testing across SDH, SONET, OTN, and Ethernet infrastructures.
