A high-speed bidirectional optical link has been required in digital transmission time-division-multiple-access telemetering systems, and visual communication systems. But a low-cost bidirectional link has not been realized. A new bidirectional digital link has now been developed. This link is available for driving current of ~32-Mbit/sec bidirectional transmission and is of low cost and small size compared with ordinary bidirectional links.
