6T OSFP is an optical transceiver form factor delivering 1. 6 Terabits per second—double the 800G standard—over eight electrical lanes running 200G PAM4 signaling each. The. Pluggable optical transceiver modules are essential components in data communication systems, widely used as optical interconnects at the termination of fiber optic links. 6T networking is becoming a reality as AI clusters and data centers continue to scale. 6T optical connectivity not only increases bandwidth, but also introduces new design considerations in areas such as thermal management, port density, cabling architecture, and protocol. This is why we are developing the world's first 1. 6 Terabit solution, using state-of-the-art technology, with WaveLogic 6 Extreme (WL6e).
