Abstract
Transceivers, networks, and methods for providing data communication to electrical devices in a vehicle, and a vehicle comprising the transceiver and network. A transceiver of the network can include a receive optical subassembly including an opto-electronic transducer configured to receive a first incoming optical signal from an optical fiber having a silica based core. Signal extraction circuitry is configured to extract data intended for an electrical device from of the incoming optical signal and provide the extracted data to the electrical device, and a transmit optical subassembly comprising a laser, such as a VCSEL, configured to transmit an outgoing optical signal to a second optical fiber having a silica based core.
Claims21
A transceiver for transmitting data to an electronic device coupled to the transceiver, wherein the electronic device is an electrical device in a vehicle, the transceiver comprising:
- a receive optical subassembly comprising an opto-electronic transducer configured to receive an incoming optical signal from first optical fiber having a silica based core;
- signal extraction circuitry configured to identify data intended for the electrical device coupled to the transceiver from the incoming optical signal and transmit the data that is intended for the electrical device to the electrical device located within the vehicle;
- and
- a transmit optical subassembly comprising a vertical cavity surface emitting laser (VCSEL) configured to transmit an outgoing optical signal to a second optical fiber having a silica based core.
A fiber optic network for providing data communication between electronic devices in a vehicle, the network comprising:
- a first optical fiber having a silica based core for conducting an optical signal;
- a first transceiver for transmitting data to a first electronic device, the first transceiver comprising:
- a receive optical subassembly comprising an opto-electronic transducer optically coupled to the first optical fiber to receive the optical signal;
- signal extraction circuitry configured to receive the optical signal and extract a first data packet intended for the first electronic device;
- and
- a transmit optical subassembly comprising a vertical cavity surface emitting laser (VCSEL) configured to transmit at least a portion of the optical signal to a second optical fiber.
A method for transferring data between electronic devices coupled to a network within a vehicle, the network comprising a plurality of transceivers coupled to the electronic devices, the method comprising the acts of:
- receiving within a first transceiver coupled to a first electronic device an optical signal from an optical fiber having a silica based core;
- identifying data intended for the first electronic device;
- transmitting the data intended for the first electronic device to the first electronic device;
- and
- transmitting data not intended for the first electronic device to a second optical fiber having a silica based core.
