Rain Tree Photonics Pte. Ltd. (RTP), a silicon photonics chip maker for hyperscale data-centers and 5G today announced the availability of a silicon photonics-based solution for 400G-DR4 optical modules. RTP’s 400G-DR4 silicon photonic engine (RTP1908) is paired with MaxLinear’s Telluride PAM4 DSP (MxL93542) to provide a high level of integration, resulting in low-cost and low-power optical module solutions.

Rain Tree Photonics’ proprietary silicon photonics engine is specifically designed to address the cost and energy consumption demands for next-generation optical interconnects in data-center applications. It provides best-in-class performance for current 100G/400G applications, with full scalability towards 800G/Terabit applications. The photonic engine is built on RTP’s unique high-performance silicon photonics integration platform with high yield and volume scalability. It is also developed to be ready for Co-Packaged Optics (CPO) architectures, while maintaining compatibility with pluggable module architectures.
