... Avago Technologies transceivers in +3.3 V systems. Data Line Interconnections Avago Technologies’ AFCT-5971LZ/ALZ fiber-optic transceivers are designed to couple to +3.3 V PECL sig- nals. The transmitter driver circuit regulates the output optical power. The regulated light output will maintain a constant output optical power provided the data pat- tern is reasonably balanced in duty cycle ...
