Electronic Modules

Yokogawa has been striving to develop heterojunction bipolar transistor IC (HBTIC) modules for 40Gbps WDM optical communication systems, employing proprietary ultra-high speed HBT devices which the company first began developing in 1983. With the HBT's ultra-high speed and low jitter characteristics, we have developed a line-up of logic ICs offering high-quality output waveforms, including a 4:1 multiplexer (MUX), 1:4 demultiplexer (DEMUX), and D flip-flop (DFF). The number of circuit elements in the IC has been increased to approximately 2,000, Furthermore, the optical modulator driver IC’s frequency has been increased to 70GHz. Of special note is our combined operation which brings together Yokogawa's R&D, design, manufacturing, marketing, and sales units to provide timely 40Gbps solutions. For the upcoming commercialization of 40Gbps, modules have been designed with V connectors for test benches and measuring instruments, GPPO compatible connectors for commercial transponders, and a CPWG for wire bonding. For our growing number of 10Gbps customers, we have a clock driver and NRZ-RZ converter.
