Optical DSP Solutions

Credo’s low power, high-performance DSPs enable optical interconnect for cloud-scale, hyperscale, and enterprise data center build-outs with 50G to 400G PAM4 optical modules and build-outs for 5G wireless service providers with 50G PAM4 devices. These full-featured DSPs utilize Credo’s industry-leading transmitters and low power BER receivers, and are optimized for cost-efficient production.

Hyper Scale & Enterprise Data Center

Credo’s extensive product portfolio includes DSPs for 100G, 200G and 400G PAM4 optical interconnects. Credo’s proprietary DSP technology and equalization techniques help compensate for optical impairments to achieve the best overall system performance, signal integrity, and power efficiency.

5G Wireless Service Provider

Credo’s 50G PAM4 DSPs operate over the full industrial temperature range of -40C to +85C module case and are ideal for use in 5G wireless/eCPRI front-, mid-, and back-haul applications. The integrated DSP technology is critical in 5G wireless applications where cost-effective solutions are required, enabling wider use of DML lasers and un-cooled optics.
