Reader/writer, optical transceiver module, and cable system
First Claim
Patent Images
1. A reader/writer, which writes data into an RF tag mounted to an end of a fiber-optic cable and reads data from the RF tag, through radio communication, the reader/writer comprising:
- an optical receiver which converts an optical signal received through the fiber-optic cable into an electric signal;
an optical transmitter which converts an electric signal into an optical signal and transmits the optical signal to the fiber-optic cable;
a radio communication unit which performs radio communication with the RF tag; and
an RF tag control unit which reads, on receiving through the optical receiver a signal that is an instruction to read data, data from the RF tag through the radio communication unit and transmits the read data to the fiber-optic cable through the optical transmitter, and writes, on receiving through the optical receiver a signal that is an instruction to write data and a signal indicating the write data, the write data thus received into the RF tag through the radio communication unit.

Abstract
A reader/writer is provided which is capable of speedily recognizing a correspondence between one end and the other end of a fiber-optic cable when a plurality of fiber-optic cables is laid. The reader/writer according to the present invention reads, on receiving through the fiber-optic cable a signal that is an instruction to read data from a RF tag mounted to an end of the fiber-optic cable, data from the RF tag through radio communication, and transmits the read data through the fiber-optic cable. Also, on receiving through the fiber-optic cable a signal that is an instruction to write data into the RF tag and a signal indicating the write data, the reader/writer writes the write instruction and the write data into the RF tag through radio communication.
