GaAs ICs in commercial OC-192 equipment

Herman William Willemsen; David John Nicholson

OC-192, with a data rate of 9.953 Gb/s, is the fastest commercial fiber-optic transport system available today. As with lower bit-rate equipment, III-V compound semiconductors play a large role in OC-192. This paper describes the technology selection, circuit design and high-speed packaging needed for the successful introduction of OC-192.
