While there is no direct Estonian manufacturer of PAM4 core switches, distributors like OMI.ee, Perel Eesti AS, and Farnell Eesti can source compatible PAM4 components and optical DSPs for high-speed networking.

Potential Estonian Distributors

• OMI.ee: Estonia's largest electronics component retailer, offering millions of products from over 1,500 suppliers. They provide a wide range of electronic components, including networking modules and optical transceivers, which may include PAM4-compatible devices for Ethernet and InfiniBand applications (omi.ee) .
• Perel Eesti AS: Specializes in industrial electronics, automation, and electromechanical components. They import and sell high-quality components, including DC/DC converters, sensors, and potentially networking modules compatible with PAM4 DSPs (perel.ee) .
• Farnell Eesti: A reliable distributor of electronic components and industrial systems, offering fast delivery and technical support. They can source PAM4-compatible optical modules and related networking hardware (ee.farnell.com) .

PAM4 Components to Consider

• Marvell PAM4 Optical DSPs: Marvell provides Spica™, Nova™, and Ara DSPs that enable 100G to 1.6T optical transceivers for Ethernet and InfiniBand networks. These DSPs are widely used in cloud, AI, and data center networks and can be integrated into compatible core switches (marvell.com) .
• Optical Transceivers: PAM4-compatible transceivers are essential for high-bandwidth interconnects. Estonian distributors can often source these modules from global suppliers like Marvell, Cisco, or Broadcom.

Recommendations

1. Contact distributors directly: Reach out to OMI.ee, Perel Eesti AS, or Farnell Eesti to inquire about PAM4-compatible optical modules or core switches.
2. Specify requirements: Provide details such as bandwidth (400G, 800G, 1.6T), interface type (Ethernet or InfiniBand), and form factor to ensure compatibility.
3. Consider global suppliers: If local stock is limited, distributors can often place special orders from Marvell or other PAM4 DSP manufacturers. By leveraging these Estonian distributors, you can source PAM4-compatible components and integrate them into high-speed core switch deployments for data centers or AI infrastructure.
