This paper describes optical fiber boards, small laser-diode (LD) and photo-diode (PD) modules for high-speed optical-bus backboards. The optical fiber board consists of embedded optical fibers in a printed circuit board. We evaluated the effect of curvature on optical loss for the embedded fiber to obtain the optimum design condition. The increase of optical loss is negligible in the condition of over 20 mm radius. The LD/PD modules are composed of a fiber holder and a receptacle with a can-type LD/PD. These modules have suitable structure for attaching to the fiber board with a minimal spare length of fiber in a small space. We measured the bit error rate between the LD and PD modules at 1 Gb/s, and confirmed that bit error rate of 10^<12> can be achieved with 16 channel bus boards.
