It uses a linear drive strategy to replace DSPs with a Transimpedance Amplifier (TIA) and Driver Chip (DRIVER) with excellent linearity and EQ capabilities. While copper cabling still offers cost and reliability advantages for short-distance connections, it faces the dual challenges of speed bottlenecks and cabling complexity in high-bandwidth, long-distance, and high-energy-efficiency scenarios. The 100G-DR-LPO specification by the LPO (Linear Pluggable Optics) MSA defines 100 Gb/s/lane 53. 125 GBd PAM4 optical interfaces, optical links using standard single-mode fiber with up to 500 m reach, and host-module electrical interfaces for hosts with DSP based SerDes and RS(544,514) FEC. In a power-constrained AI cluster or data center, every Watt of power that is used by the network is a Watt of power that cannot be allocated to compute.
Non-retimed LPO is not a viable option at 200G PAM4 The O-SNR required is excessively high for typical 200G C2M channels Tx-retimed TRO is highly effective in reducing optical SNR penalty >
