This has driven the emergence of two major approaches: Co-Packaged Optics (CPO) and Linear Pluggable Optics (LPO). Understanding the technical differences, advantages, and operational implications of each is essential for network architects planning next-generation data center. In the LPO architecture: The transmitter uses a high-linearity driver chip to directly drive the optical modulator, converting the electrical signal into an optical signal. The receiver uses a high-linearity transimpedance amplifier (TIA) for photoelectric conversion and amplification. Pluggable optical transceivers (like QSFP-DD and OSFP) have been the backbone of data center. Among the emerging technologies, LPO (Li...
