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.
