13. An apparatus comprising:
a first electro-optical interface electrically connected to a first USB system;
a second electro-optical interface electrically connected to a second USB system; and
an optical communication channel optically connecting the first electro-optical interface with the second electro-optical interface, wherein the first electro-optical interface is configured to:
receive an electrical USB sideband signal from the first USB system, the USB sideband signal being associated with a USB communication request;
convert the electrical USB sideband signal to an optical USB sideband signal; and
transmit the optical USB sideband signal to the second electro-optical interface, and wherein the second electro-optical interface is configured to:
detect a presence of the optical USB sideband signal received over the optical communication channel;
responsive to the detecting:
determine that the USB communication request corresponds to a USB communication mode; and
perform a sideband negotiation;
enable the USB communication mode;
determine a specified number of channels associated with the USB communication request; and
perform USB communication using the specified number of channels over the optical communication channel in the USB communication mode.
