Abstract
Systems and methods to implement a USB and Thunderbolt optical signal transceiver are described. One method includes detecting presence of a USB sideband signal received over an optical communication channel and associated with a USB communication request. Responsive to the detecting, the method may determine that the USB communication request corresponds to a USB communication mode and perform a sideband negotiation. The USB communication mode may be enabled. A specified number of channels associated with the USB communication request may be determined. USB communication may be performed using the specified number of channels over the optical communication channel in the USB communication mode.
Claims20
A method comprising:
- detecting presence of a USB sideband signal received over an optical communication channel and associated with a USB communication request;
- responsive to the detecting:
- determining that the USB communication request corresponds to a USB communication mode;
- and
- performing a sideband negotiation;
- enabling the USB communication mode;
- determining a specified number of channels associated with the USB communication request;
- and
- performing USB communication using the specified number of channels over the optical communication channel in the USB communication mode.
A method comprising:
- checking for but failing to detect a presence of a USB sideband signal received over an optical communication channel;
- detecting a presence of an LFPS signal received over the optical communication channel and associated with a USB communication request;
- determining that the USB communication request is associated with a USB communication mode responsive the detecting;
- performing an LFPS test responsive to the detecting;
- enabling the USB communication mode;
- determining a specified number of channels associated with the USB communication request;
- and
- performing USB communication using the specified number of channels over the optical communication channel in the USB communication mode.
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.
