Closely relevant to the popular co-packaged optics (CPO) and pluggable optics solutions, the Linear Direct Drive technology moves the CDR on boards and the ODSP inside modules to SerDes, and enhances the linear compensation capabilities of the DRV and TIA in links to balance power.

Linear Drive Pluggable Optics (LPOs) have gained tremendous attention during 2023 and this document attempts to de-mystify the terminology. The focus is on 400G and 800G LPOs using 56GBd lanes. It's all about the SerDes! One of the first myths is that LPO transceivers do something new, but in. With introduction of lower power DSP that can fit into CFP2 power envelop the ACO modules were replaced by the DCO modules. ACO Module TX OE Response Implies MCB+Module+Optics has only 4 dB loss at Nyquist! Can't Deliver Large Signal Across 11 dB Channels! Hungary AGC ACO Module RX OE Response. In the data center network system, the application of linear pluggable optics (LPO) modules has certain advantages in terms of cost, power consumption, and latency compared to traditional digital signal processor (DSP) modules. However, it also poses significant challenges to the end-to-end system. Linear, direct-drive, un-retimed, pluggable optics Too good to be true? optics – Too good to be true? Samtec, MACOM propose CEI-112G-LINEAR standardization effort – much debate + a contentious vote to proceed. These high-performance parts have been leveraged in leading module and system level designs and enable highly efficient interconnect spanning both short reach and long. The emergence of generative artificial intelligence (AI) technologies like ChatGPT is driving the rapid growth of global computing power and data center bandwidth requirements, as well as accelerating the application of new optoelectronic technologies such as Linear Direct Drive.
