Provide optical module switches

Optical module solutions for switches include pluggable optics, co-packaged optics (CPO), silicon photonics, and MEMS-based optical switches, each offering trade-offs in power efficiency, performance, and serviceability.Pluggable OpticsPluggable optics, such as QSFP-DD, OSFP, and OSFP 1.6T modules, are widely used in data centers for connecting switches to servers or other network devices. They integrate photonic integrated circuits (PICs) and electronic ICs (EICs) and can support speeds from 400G to 1.6T per port. Pluggable optics are modular and serviceable, allowing easy replacement in case of failure, and are compatible with multiple switch platforms . Cisco and other vendors provide high-density pluggable modules optimized for AI and HPC workloads, offering backward compatibility and heat-sink integration for high-speed applications .Co-Packaged Optics (CPO)CPO integrates the optical engine directly into the ASIC package, reducing the electrical path between the switch core and optics. This approach minimizes insertion loss and power consumption, especially at high SerDes speeds (e.g., 400G per lane and beyond), . NVIDIA's CPO solutions demonstrate 5x better power efficiency and higher network resiliency, making them suitable for large-scale AI and GPU-intensive data centers . However, CPO can reduce configurability and serviceability, as failed optics embedded in the package are harder to replace . CPO is increasingly considered essential for next-generation high-speed switches where traditional pluggable optics face limitations.Silicon PhotonicsSilicon photonics is a key technology for both pluggable and co-packaged optics. It enables high-speed optical transmission with lower power consumption and supports integration with ASICs for AI and HPC workloads . Silicon photonics modules can be deployed in QSFP-DD, OSFP, or custom form factors, providing high-density, low-latency connectivity.MEMS-Based Optical SwitchesMEMS (Micro-Electro-Mechanical Systems) optical switches, such as 1xN or 2x2 configurations, are used for fiber-to-fiber switching, protection, and monitoring in optical networks . They offer fast switching (
