• 12-channel DC to 622-Mbit/s/ch optical transmitter and receiver have been developed for high-capacity and rather long (about 100m) bit-parallel raw data transmission in intra-and inter-cabinet interconnection of large-scale switching, routing and computing system. Bit-parallel raw data transmission is done by using a bit-by-bit operational automatic decision threshold control receiver circuit with a DC-coupled configuration, the pin-PDs with their anodes and cathodes sparated in a channel-by-channel manner, and a receiver preamplifer with a low-pass filter. The transmiter consists of a 12-channel LDsub-assembly unit and a LD driver LSI. The LD sub-assembly unit consists of a 12-channel array of high temperature characteristic 1.3-μm planar buried hetero-structure (PBH) LDs and 62.5/125 graded-index multi-mode fibers (G162.5 MMFs). The 1.3μm PBH LDs and the G162.5MMFs are optically coupled by passively visual alignment technology on the Si V-groove. The receiver consists of a 12-channel pin-PD sub-assembly unit and a receiver LSI. The pin-PD sub-assembly unit consist of a 12-channel array of pin-PDs and G162.5MMFs. They are optically coupled by using a flip-chip bonding on the Si V-groove. The transmitter and receiver each have eleven data channels and one clock channel. The size is as small as 3.6cc for each modules, and the power consumptions are 1.7W (transmitter) and 1.35W (receiver). They transmitted a bit-parallel raw data through a 100-meter ribbon of G162.5 MMFs in an ambient temperature range of 0-70゜C. They provide a synchronous PECL interface parallel link for with a 3.3-V single power supply.
