Abstract
An electro-optical link is provided. In an example embodiment, the electro-optical link includes a number of vertical cavity surface emitting lasers (VCSELs); one or more drivers that operate the VCSELs such that each of the VCSELs selectively emits an optical signal; one or more multiplexers that multiplex a number of optical signals into an optical fiber, each optical signal emitted by one of the VCSELs; and one or more optical fibers. At least two optical signals are multiplexed into each optical fiber of the one or more optical fibers. In some example configurations eight or sixteen optical signals are multiplexed into one optical fiber.
