摘要： An optical transmission apparatus includes a light receiving element and an optical waveguide. The light receiving element receives light. The optical waveguide includes a core, a clad and a concave portion. The clad is adjacent to the core. The concave portion is formed in a portion of the core or a portion of the clad and diffuses the light. The portion of the core or the portion of the clad emits the light toward the light receiving element.

摘要： An image transfer apparatus includes a generator, a scrambling device, first and second converters, a descrambling device, a detector, and a retransmission request unit. The generator generates packets each having an error detecting code added to image data. The scrambling device scrambles the generated packets on a packet-to-packet basis to reduce repetition of identical data. The first converter subjects the scrambled packets to parallel-to-serial conversion, and transfers the packets to a target apparatus. The second converter receives the scrambled packets from the target apparatus, and subjects the received packets to serial-to-parallel conversion. The descrambling device descrambles the packets subjected to the serial-to-parallel conversion. The detector detects an error from the error detecting code of each of the descrambled packets. Upon detection of the error, the retransmission request unit requests the target apparatus to retransmit the packet in which the error is detected.
