Open Optical & Packet Transport

This project group will define Dense Wavelength Division Multiplexing (DWDM) open packet transport architecture that triggers new innovation and avoids implementation lock-ins. Open DWDM systems include open line system & control, transponder & network management and packet-switch and router technologies. Facebook has worked with partners to test Voyager, a networking solution for Open Packet DWDM networks — and what Facebook believes is the industry’s first “white box” transponder and routing solution.
