Performance Limitations and Optimizations of Linear Driver Optics for 200G/Lane and beyond

We studied performance limitations and optimizations using digital equalization and modulation bandwidth in linear-driver-optics for 200G/lane and beyond. The results show linear pluggable modules can support 30dB bump-to-bump loss for 200G/lane using an enhanced CTLE. (e-mail: jzhou@hisensebroadband.com ).
